Description

Technical Field

[0001] The utility model relates to a motor, in particular to an AC synchronous closed reluctance motor with a closed electromagnetic field. Background Art

[0002] The existing various AC motors are electric traction devices that convert electrical energy into mechanical energy. They are mainly composed of a stator, a rotor and the air gap between them. After the stator winding is connected to a three-phase AC power supply, a rotating magnetic field is generated and the rotor is cut to obtain torque. The three-phase AC asynchronous motor has the advantages of simple structure, reliable operation, low price, strong overload capacity, and convenient use, installation and maintenance. It is widely used in various fields. The stator consists of three parts: the core, the winding and the base. The rotor consists of an iron core and a winding. The rotor winding is a squirrel cage type and a wire wound type. The squirrel cage rotor is composed of copper bars inserted into the rotor core slot, and then all the copper bars are welded to two copper end rings; the wire wound rotor winding is the same as the stator winding, and the winding is composed of a coil and placed in the rotor core slot. Although the structures of the squirrel cage and wire wound motors are different, the working principles are the same.

[0003] The working principle of the three-phase asynchronous motor is based on the interaction between the stator rotating magnetic field (the synthetic magnetic field generated by the three-phase current in the stator winding) and the rotor current (the current in the rotor winding). When the symmetrical three-phase winding of the stator is connected to a three-phase power supply, a symmetrical three-phase current will be passed into the winding, and a rotating magnetic field will be generated in space. The magnetic field rotates along the inner circumference of the stator. When the magnetic field rotates, the conductor of the rotor winding cuts the magnetic flux to generate an induced electromotive force E. Due to the existence of the electromotive force E, a rotor current I will be generated in the rotor winding. According to Ampere's electromagnetic force law, the interaction between the rotor current and the rotating magnetic field will generate an electromagnetic force F (its direction is determined by the left-hand rule). This force forms an electromagnetic torque on the rotor shaft, and the direction of the torque is the same as the direction of rotation of the rotating magnetic field. The rotor is affected by this torque and rotates in the direction of rotation of the rotating magnetic field. However, the rotation speed n of the rotor is always smaller than the rotation speed n0 of the rotating magnetic field (called the synchronous speed), because if the two speeds are equal, there is no relative motion between the rotor and the rotating magnetic field, and the rotor conductor does not cut the magnetic flux, so the induced electromotive force and current cannot be generated, and there is no electromagnetic torque, and the rotor will not continue to rotate. Therefore, the speed difference between the rotor and the rotating magnetic field is the main factor to ensure the rotation of the rotor.

[0004] The switched reluctance motor is an AC motor. When the rotor rotates, the magnetic resistance of the magnetic circuit must change as much as possible. Therefore, the stator and rotor of the motor both adopt a double salient pole structure and are made of stacked silicon steel sheets. A simple concentrated winding is installed on each stator pole, and the windings on the two radially opposite stator poles are connected in series or in parallel to form one phase. There are no windings or permanent magnets on the rotor. According to the number of phases of the motor, it can be divided into odd phases and even phases. According to the magnetic circuit structure of the motor, it can be divided into a two-pole long magnetic circuit structure and a four-pole short magnetic circuit structure. According to the power-on excitation mode of the motor, there are single-phase excitation and multi-phase excitation.

[0005] The switched reluctance motor (SRM) used in the switched reluctance motor speed control system is the component that realizes the electromechanical energy conversion in the SRD, and is also the main feature that distinguishes the SRD from other motor drive systems. The SRM is a double-saliency variable reluctance motor, and the salient poles of its stator and rotor are stacked by ordinary silicon steel sheets. The rotor has neither windings nor permanent magnets, and the stator poles are wound with concentrated windings. The two radially opposite windings are connected together, which is called "one phase". The SR motor can be designed into a variety of different phase structures, and the number of stator and rotor poles can be matched in many different ways. The large number of phases and small step angle are conducive to reducing torque pulsation, but the structure is complex, and there are many main switch devices, which is costly. The four-phase (8 / 6) structure and the six-phase (12 / 8) structure are more commonly used today. The switched reluctance motor has a simple structure, a simple motor structure, low cost, and can be used for high-speed operation. The structure of the SRM is simpler than that of the squirrel cage induction motor. Its rotor has extremely high mechanical strength and can be used for ultra-high-speed operation (such as tens of thousands of revolutions per minute). In terms of the stator, it has only a few concentrated windings, so it is easy to manufacture and has a simple insulation structure. The circuit is reliable and the power circuit is simple and reliable. Because the direction of the motor torque is independent of the direction of the winding current, that is, only the unilateral phase winding current is required, the power circuit can have one power switch per phase. In contrast, the asynchronous motor winding needs to flow through a bidirectional current, and the PWM inverter power circuit that supplies power to it requires two power devices per phase. Therefore, the switched reluctance motor speed control system requires fewer power components than the PWM inverter power circuit, and the circuit structure is simpler. In addition, the two power switch tubes in each bridge arm of the PWM inverter power circuit directly span the DC power supply side, which is prone to direct short circuit and burnout of the power device. In the switched reluctance motor speed control system, each power switch device is directly connected in series with the motor winding, which fundamentally avoids the direct short circuit phenomenon. Therefore, the protection circuit of the power circuit in the switched reluctance motor speed control system can be simplified, which reduces the cost and has higher reliability. The system has high reliability. From the electromagnetic structure of the motor, each winding and magnetic circuit are independent of each other, and each generates electromagnetic torque within a certain shaft angle range. Unlike general motors, a rotating magnetic field must be generated under the joint action of each phase winding and magnetic circuit for the motor to operate normally. From the control structure point of view, each phase circuit supplies power to one phase winding, and generally works independently of each other. Switched reluctance motor; large starting torque and low starting current. The controller outputs less current, and the motor obtains a larger starting torque, which is a major feature of this system. The data of typical products is that when the starting current is 15% of the rated current, the starting torque is 100% of the rated torque, and when the starting current is 30% of the rated current, the starting torque can reach 250% of its rated torque. Compared with this, the starting characteristics of other speed control systems, such as 100% current for DC motors and 300% current for squirrel cage induction motors, obtain 100% torque.The advantages of small starting current and large torque can also be extended to the low-speed operation section, so this system is very suitable for those machines that need heavy-load starting and long-term low-speed heavy-load operation. Frequent start and stop; suitable for frequent start and stop and forward and reverse conversion operation. The system has the characteristics of high starting torque and low starting current, which makes the current impact small during the starting process, and the motor heat is smaller than that during continuous rated operation. It is suitable for frequent start and stop and forward and reverse conversion operation, and has good speed regulation performance. There are at least four main operating parameters and common methods for controlling the switched reluctance motor: phase conduction angle, related break angle, phase current amplitude, phase winding voltage, which is flexible and convenient. According to the operating requirements and conditions of the motor, different control methods and parameter values ​​can be adopted to make it run in the best state (such as maximum output, highest efficiency, etc.), and it can also realize specific curves of various functions. For example, the motor has exactly the same four-quadrant operating capacity, and has the highest starting torque and load capacity curve of the series-excited motor. It can be used for speed closed-loop control, and it can easily form a zero-static speed regulation system.

[0006] The synchronous reluctance motor is essentially a synchronous motor with reluctance properties. Its operating principle is similar to that of the switched reluctance motor, and it is fundamentally different from traditional AC and DC motors. Unlike traditional motors, it does not rely on the interaction between the stator and rotor magnetic fields to form torque, but follows the principle that the magnetic flux is always closed along the path with the minimum reluctance. The magnetic pull generated by the reluctance change caused by the rotor at different positions forms torque. This torque is called reluctance torque. Unlike the stator switch rotating magnetic field of the switched reluctance motor, the stator magnetic field of the synchronous reluctance motor is a sinusoidal rotating magnetic field. The stator of the synchronous reluctance motor generally adopts the stator structure of the traditional three-phase AC motor, but its rotor structure is relatively special, with many slots on the rotor. Its special rotor structure realizes the huge reluctance difference between the AC and DC axis magnetic circuits of the synchronous reluctance motor, presenting a strong salient polarity, thereby generating a driving torque with reluctance properties. The stator of the synchronous reluctance motor generally adopts the stator structure of the traditional three-phase AC motor. The difference is mainly in the rotor structure. With the development of technology, the rotor structure of synchronous reluctance motor is constantly evolving. At present, there are two main rotor structures, transverse lamination (TLA) and axial lamination anisotropic (ALA). The ALA structure is made of high magnetic permeability materials and non-magnetic insulating materials alternately stacked along the axial direction. It has very strong salient polarity, so the torque density and power factor are high, but the process is complicated and inconvenient to manufacture. The TLA structure adopts the traditional stamping and lamination process. The rotor structure is simple, the mechanical strength is high, and the production cost is low. However, the salient polarity is not as strong as the ALA structure, so the torque density and power factor are inferior to the ALA structure. Synchronous reluctance motor essence Synchronous reluctance motor is a synchronous motor with reluctance properties. Its operating principle follows the principle that the magnetic flux is always closed along the path with the minimum reluctance, and the magnetic pull generated by the reluctance change caused by the rotor at different positions forms the torque. Compared with traditional DC motors, synchronous reluctance motors have no brushes and rings, are simple, reliable and easy to maintain. Compared with traditional AC asynchronous motors, synchronous reluctance motors have no windings on their rotors, so there is no rotor copper loss, which improves the efficiency of the motor. Compared with switched reluctance motors, synchronous reluctance motors have smooth rotor surfaces and more continuous magnetic resistance changes, which avoids the problems of torque pulsation and high noise during the operation of switched reluctance motors. At the same time, the stator of a synchronous reluctance motor has a sinusoidal magnetic field, simple control, and a mature hardware platform, thereby reducing the cost of the drive control system. Compared with permanent magnet synchronous motors, synchronous reluctance motors have no permanent magnets on their rotors, are less expensive, have no problems with weak magnetic field and demagnetization, and have more stable efficiency over the long term.

[0007] The existing brushless DC motors are not real DC motors. These so-called DC motors only have DC input current, which is not stable. The internal magnetoelectric working process and working principle of brushed DC motors and brushless DC motors are AC electromagnetic fields. Therefore, these so-called DC motors still have iron loss and copper loss that are inevitable in transformers. Due to the existence of iron loss and copper loss, brushed DC motors and brushless DC motors have great energy loss and serious heat generation when rotating at high speed, so it is difficult to run at ultra-high speed. Now all motors and DC motors are developed based on the Faraday armature type. The working principle of DC generators is to convert the alternating electromotive force induced in the armature coil into DC electromotive force when it is led out from the brush end by the commutation of the commutator and the brush. The direction of the force on the conductor is determined by the left-hand rule. The brushless motor is the stator and rotor of the ordinary DC motor interchanged. Its rotor is a permanent magnet to generate air gap flux: the stator is an armature, which is composed of multi-phase windings. The structure of the stator of a brushless motor is the same as that of an ordinary synchronous motor or induction motor. A multi-phase winding (three-phase, four-phase, five-phase, etc.) is embedded in the iron core. The winding can be connected in a star or triangle shape and connected to each power tube of the inverter for reasonable phase change. The rotor is mostly made of rare earth materials with high coercivity and high remanent magnetic density such as samarium cobalt or neodymium iron boron. Due to the different positions of the magnetic materials in the magnetic poles, they can be divided into surface poles, embedded poles and annular poles. Since the motor body is a permanent magnet motor, it is customary to call the brushless motor a permanent magnet brushless DC motor. The two copper brushes or carbon brushes of the brushed motor are fixed to the rear cover of the motor through an insulating seat to directly introduce the positive and negative poles of the power supply to the commutator of the rotor, and the commutator is connected to the coils on the rotor. The polarity of the three coils is constantly alternating to form a force with the two magnets fixed on the shell to rotate. Since the commutator is fixed to the rotor, and the brush is fixed to the housing (stator), the brush and the commutator will constantly rub against each other when the motor rotates, generating a lot of resistance and heat. Therefore, the efficiency of the brushless motor is low and the loss is very large. However, it also has the advantages of simple manufacturing and low cost.

[0008] Since the armature circuit resistance and inductance of the motor are small, and the rotating body has a certain mechanical inertia, when the motor is powered on, the armature speed and the corresponding back electromotive force are very small at the beginning of the start, and the starting current is very large. The maximum can reach 15 to 20 times the rated current. This current will cause disturbances in the power grid, mechanical shocks to the unit, and sparks in the commutator. Therefore, direct closing starting is only suitable for motors with a power of no more than 4 kilowatts (the starting current is 6 to 8 times the rated current). In order to limit the starting current, a specially designed variable resistor is often connected in series in the armature circuit, which is widely used in various small and medium-sized DC motors. However, due to the large energy consumption during the starting process, it is not suitable for motors that are frequently started and medium and large DC motors. However, for some special needs, such as urban trams that are frequently started, in order to simplify equipment, reduce weight and facilitate operation and maintenance, the series resistance starting method is usually used. For DC motors with larger capacity, voltage reduction starting is usually used. That is, the motor armature is powered by a separate adjustable voltage DC power supply. Controlling the power supply voltage can not only make the motor start smoothly, but also achieve speed regulation. This method requires more complicated power supply equipment.

[0009] The coil of the hollow cup motor looks like a water cup, so it is called a hollow cup. As a DC motor, the hollow cup motor breaks through the rotor structure of the traditional motor in structure, and its weight and moment of inertia are greatly reduced, thereby reducing the mechanical energy loss of the rotor itself. Due to the change in the structure of the rotor, the operation characteristics of the motor have been improved. It not only has outstanding energy-saving characteristics, but more importantly, it has control and drag characteristics that iron core motors cannot achieve. The coreless rotor, this novel rotor structure completely eliminates the power loss caused by the eddy current formed by the iron core. Energy-saving characteristics The energy conversion efficiency is very high, and its maximum efficiency is generally above 70%. The control characteristics start and brake quickly, respond very quickly, and the mechanical time constant is less than 28 milliseconds (iron core motors are generally above 100 milliseconds); under the high-speed operation state within the recommended operating area, the speed can be easily adjusted sensitively. Drag characteristics: The operation stability is very reliable, and the speed fluctuation is very small. As a micro motor, its speed fluctuation can be easily controlled within 2%. In addition, the energy density of the hollow cup motor has been greatly improved. Compared with the iron core motor of the same power, its weight and volume are reduced by 1 / 3-1 / 2. Because the hollow cup motor has overcome the insurmountable technical obstacles of the iron core motor, and its outstanding features are concentrated in the follow-up system that requires fast response of the main performance of the motor. Such as rapid adjustment of the flight direction of missiles, follow-up control of high-magnification optical drives, fast automatic focusing, highly sensitive recording and detection equipment, industrial robots, bionic prostheses, model airplanes, etc., but because the coil production process of the hollow cup motor is extremely complex, the degree of production automation is far less than that of the iron core motor, resulting in high production costs, high labor costs, and high requirements for the operator's skill level. It brings many difficulties and limitations to large-scale production. Since the coil of the hollow cup motor can only be made very thin, it can only be used in the field of micro motors, with low torque and low power. The general power is only a few watts, and the maximum is only a few hundred watts, while the new energy electric vehicle motor is generally more than tens of kilowatts.

[0010] New energy vehicles have three core components: batteries, motors and electronic controls. Motors generally use three-phase permanent magnet synchronous motors and three-phase AC induction motors. There are also three-phase synchronous reluctance motors or switched reluctance motors. These are high-power AC motors. Since new energy vehicles generally use AC motors and the battery pack outputs DC power, electronic controls have to be added to rectify DC power into three-phase AC power. The comprehensive energy efficiency of these three-phase AC motors is only about 85% to 92%, which is equivalent to a mileage reduction of one or two hundred kilometers. This is very important for new energy vehicles now. my country's future standard requirements for new energy vehicle motors are a peak power ratio of 5 to 7 kilowatts per kilogram, and the duration is only 30 seconds. Summary of the invention

[0011] The existing AC motor is widely used in all walks of life because of its simple structure and low price. It is the most widely used motor in the world. Most of the global electricity generation is consumed by AC motors. Therefore, the energy efficiency of AC motors is very important. Most of the AC motors used in my country are inefficient motors with energy efficiency below level 3. The energy efficiency of small-power AC motors is generally less than 80%, but even small AC motors with energy efficiency of level 1 do not exceed 90%. Only the efficiency of high-power AC motors with energy efficiency of level 1 can reach 97%, but the high cost makes it difficult to promote and apply. The main reason for the bulky and low energy efficiency of existing AC motors is that the stator wire winding is an open wire winding. There are defects in the original design. In order to facilitate the installation of the rotor, the two ends of the wire winding avoid the rotor end face with a semicircular ring. Therefore, the electromagnetic field of this wire winding is not closed, and the two ends are open electromagnetic fields, resulting in unsatisfactory induction effect on the rotor. Secondly, because the wire winding needs to be supported by the iron core and the induced magnetic field is enhanced at the same time, the use density of the wire winding is limited. The adverse consequences of this open wiring method are, first, a significant increase in the core vortex Current iron loss, secondly, it limits the amount of wire used, limits the reduction of wire resistance, and thus limits the motor power. Thirdly, the redundant wires at both ends of the wire winding are almost half, which is equivalent to increasing the resistance copper loss by half. Fourthly, the redundant wires at both ends of the wire winding surround the open rotor in a semicircle, forming a useless axial variable magnetic field at both ends of the rotor, thereby generating unnecessary eddy current iron loss in the rotor core, and also generating ring current in the short-circuit rings at both ends of the rotor, increasing copper loss. Fifthly, in order to avoid the adverse effects of too many redundant wires at both ends of the wire winding, the length of the rotor is usually much greater than Diameter, while AC motors generally use 50 Hz industrial frequency power supply. When the speed is limited, increasing the diameter of the rotor is the best way to increase the motor output power and power. Sixth, because the length of the rotor is much larger than the diameter, the aluminum or copper bars of the rotor must be made longer, which increases the resistance of the rotor and the stress deformation of the pot bars or copper bars. Seventh, the best shape of the inductor is cylindrical, followed by square, and the worst is rectangular. The larger the ratio of width to thickness, the worse the inductance effect, and the existing AC motor winding method is exactly the worst rectangle. In summary, in order to avoid the rotor, the wire winding of the existing AC motor has to be wound into a semicircular ring at both ends to form an open electromagnetic field, and it is also necessary to use an iron core stator to fix the wire winding, and at the same time use the iron core stator to compensate for the magnetic field loss of the open electromagnetic field. In summary, the root cause of a series of problems in the existing AC motor is that the wire winding is an open electromagnetic field. Originally, the perfect wire winding must be a closed electromagnetic field. What needs to be done is how to make the wire winding of the closed electromagnetic field bypass the output shaft of the rotor instead of bypassing the entire rotor.

[0012] In order to overcome the shortcomings of existing AC motors and improve the energy efficiency and power-to-weight ratio of AC motors, the utility model aims at the shortcomings of existing AC motors and adopts a wire frame with a closed electromagnetic field. The current direction of the wire frame surrounds the axial direction and end surface of the inductor to form a closed induction magnetic field. The wire frame covers the entire rotor inductor and only needs to avoid the shaft rod instead of the entire rotor end surface. The wire frame is fixed by the casing, and even a coreless stator can be used to achieve low resistance, high power-to-weight ratio, large output torque and high energy efficiency.

[0013] In order to achieve the above-mentioned purpose, the first technical solution adopted by the utility model includes a rotor, a casing, a wire frame, and a bearing, characterized in that: the rotor includes a shaft and a magnetic resistance body, the magnetic resistance body is a silicon steel laminated iron core with magnetic resistance characteristics, the shaft is tightly connected to the magnetic resistance body, the magnetic resistance body is coaxially mounted with the shaft, one end of the shaft serves as a power output shaft, the casing is a fixing member supporting the wire frame and the rotor, the casing is cylindrical or a cylindrical frame, one end or both ends are covered, the center of the two ends of the casing has a bearing seat, the shaft of the rotor is equipped with bearings, and the bearing sleeves are mounted on the two ends of the casing In the central bearing seat, the wire frame is arranged inside the housing, the wire frame is a rectangular wire winding, or a circular wire winding, the wire frame has two phases, three phases or multiple phases, the two phases, three phases or multiple phases are distributed along the circumference of the rotor at a certain angle, the wire frame is sheathed with the magnetic resistance body, the current direction of the wire frame surrounds the axial direction and end surface of the magnetic resistance body to form a closed induced magnetic field, there is a rotating gap between the wire frame and the magnetic resistance body, the housing and the wire frame are fixed, the wire frame is passed with alternating current to form a rotating magnetic field, and the rotating magnetic field drags the magnetic resistance body to rotate relatively in the wire frame.

[0014] The second technical solution adopted by the utility model includes a rotor, a casing, a wire frame, a bearing, and a stator, and is characterized in that: the rotor includes a shaft and a magnetic resistance body, the magnetic resistance body is a silicon steel laminated iron core with magnetic resistance characteristics, the shaft is tightly connected to the magnetic resistance body, the magnetic resistance body is coaxially mounted with the shaft, one end of the shaft serves as a power output shaft, the casing is a fixing member supporting the stator and the rotor, the casing is cylindrical or a cylindrical frame, one end or both ends have a cover, the center of the two ends of the casing has a bearing seat, the shaft of the rotor is equipped with a bearing, the bearing is sleeved in the bearing seat at the center of the two ends of the casing, and the wire frame is A rectangular wire winding or an annular wire winding, wherein the wire frame is covered with a stator, the stator has a circular opening, the stator covers the magnetic resistance body, the axial height of the stator is equal to or greater than the axial height of the magnetic resistance body, there is a rotation gap between the circular opening of the stator and the magnetic resistance body, the wire frame has two phases or three phases, the two phases or three phases are distributed along the circumference of the rotor at a certain angle, the wire frame covers the magnetic resistance body, the current direction of the wire frame surrounds the axial direction and end surface of the magnetic resistance body to form a closed induced magnetic field, the wire frame is passed with alternating current to form a rotating magnetic field, and the rotating magnetic field drags the magnetic resistance body to rotate relatively in the circular opening of the stator.

[0015] The magnetic resistance body is a silicon steel laminated core with two salient poles, which is axially twisted within 90 degrees and presents a twisted twist shape, or the magnetic resistance body is a silicon steel laminated core with multiple salient poles, or the magnetic resistance body is a silicon steel laminated core, the silicon steel laminated core has a plurality of V-shaped magnetic isolation grooves, the magnetic isolation grooves may be embedded with permanent magnets, and the diameter of the magnetic resistance body is equal to or greater than the height.

[0016] The magnetic resistance body is a silicon steel laminated core with two salient poles, which is axially twisted within 90 degrees and is in the shape of a twisted surface. In this way, the dynamic balance in any rotation direction can be guaranteed. There is a closed-loop conductor in the groove of the two salient poles of the magnetic resistance body. The closed-loop conductor is also in the shape of a twisted surface. The closed-loop conductor is an aluminum conductor or a copper conductor. In this way, the electromagnetic induction force can be strengthened. The silicon steel laminated core can be provided with a plurality of V-shaped magnetic isolation grooves, and the magnetic isolation grooves may be embedded with permanent magnets to increase the magnetic field. The axial twisting within 90 degrees means that the salient pole magnetic resistance body is twisted from one end face to the other end face by no more than 90 degrees.

[0017] The outer periphery of the magnetic resistance body is tightly covered with an aluminum tube sleeve to form a short-circuit ring. The length of the aluminum tube sleeve is equal to or greater than the length of the magnetic resistance body. In this way, the asynchronous induction start can be directly performed with AC power. When the natural frequency of the power supply is close, the magnetic resistance body will automatically resonate and synchronize with the power supply frequency. At this time, the rotor is synchronized with the power supply frequency. In this way, there is no need to use a position sensor and a motor controller.

[0018] The wire frame has three phases, the stator is a regular hexagonal silicon steel sheet core with a round opening in the middle, the three-phase wire frames are star-shaped and cross each other along the periphery of the hexagonal stator, and are evenly distributed at 120 degrees, each phase wire frame is divided into two groups, and the two groups of wire frames are distributed in parallel on the two sides of the shaft rod, the wire ends of the three-phase wire frames are connected according to the star connection method of the three-phase asynchronous induction motor, or are connected according to the triangle connection method, the casing is a regular hexagonal cylinder with a front cover and a rear cover, the center of the two ends of the casing has a bearing seat, the center lines of the six faces of the inner wall of the casing have axial convex strips, or, the center lines of the six faces of the stator have axial convex strips, the width of the axial convex strips is equal to or greater than the diameter of the shaft rod, and the axial convex strips are located between two adjacent groups of wire frames.

[0019] The wire frames have three phases: U, V, and W. Each phase has two groups of wire frames, and each group has several wire frames. Each wire frame of the three phases U, V, and W is interlaced and set in a star shape along the periphery of the hexagonal stator. That is, after the U phase completes the first circle, the V phase completes the second circle, and then the W phase completes the third circle. Then, the U phase continues to complete the fourth circle, the V phase completes the fifth circle, and the W phase completes the sixth circle, and so on. This has the advantage of eliminating the difference in induction intensity caused by the gap difference at the end surface of the U, V, and W three-phase wire frames.

[0020] The wire frame has three phases, and the three-phase wire frame is respectively covered with three T-shaped silicon steel sheet iron core stators, three arc-shaped silicon steel sheet iron core stators, and three arc-shaped silicon steel sheet iron core stators are distributed in an equilateral triangle, and are combined into a stator with an inner circular opening. The inner circular opening of the stator covers the rotor. The wire ends of the three-phase wire frame are connected according to the star connection method of the three-phase asynchronous induction motor, or are connected according to the triangle connection method. The casing is an equilateral triangle tube, or is a hexagonal tube composed of three long equilateral faces and three short equilateral faces, with a front end cover and a rear end cover, and the two ends of the casing are There is a bearing seat in the center, and the three inner angles of the casing have fixed angles, and the fixed angles are in the shape of an inverted isosceles triangle rod. The fixed angles are located between two adjacent groups of wire frames, or the casing is composed of a triangular skeleton and a triangular tube, and the triangular skeleton is composed of two equilateral triangle cover plates and three isosceles triangle rods. There are bearing seats in the centers of the two equilateral triangle cover plates, and the three corners of the equilateral triangle cover plates have screw holes. There are screw holes in the centers of the two ends of the isosceles triangle rod, and bolts are used to connect the two equilateral triangle cover plates and the three isosceles triangle rods.

[0021] The motor can be installed in two ways: horizontal and vertical. When the installation is horizontal, the bottom surface of the casing has a base frame, and the base frame has screw holes. When the installation is vertical, the front end of the casing has a base frame, and the base frame has screw holes. The side of the casing is provided with wire lead-out holes and screw holes, the rear cover is provided with a wiring bridge and an insulating wire box, the outer surface of the casing is provided with heat sinks, and the heat sinks are axially distributed. The shaft extends from the rear cover and is connected to a cooling fan, and the rear end cover has a fan cover, or the rear end cover is provided with wire lead-out holes and screw holes, and the rear end cover has a wiring bridge and an insulating wire box.

[0022] When the conductor frame is a three-phase multi-group, the electromagnetic field arrangement of the multi-group three-phase conductor frame is a dipole magnetic field arrangement, a quadrupole magnetic field arrangement, a sextupole magnetic field arrangement, or an octupole magnetic field arrangement.

[0023] The closed reluctance motor has a position sensor, which includes one or more of an electromagnetic position sensor, a magnetic position sensor, and a photoelectric position sensor. The casing has an electromagnetic induction coil, or a Hall circuit, or a rotary transformer at the tail end of the shaft, or a magnetic encoder, or a photosensitive signal sensor. The current passes through the feedback of the position sensor and the control of the motor controller, so that the wire frame forms a rotating magnetic field to drive the reluctance body to rotate synchronously.

[0024] The lead frame is solidified with epoxy resin to strengthen the structure.

[0025] There are steps, or clamping grooves and clamping springs on the shaft rods on both sides of the magnetic resistance body to fix the position of the bearing.

[0026] The beneficial effects of the utility model are as follows: the existing AC motors and reluctance motors are widely used in various industries due to their simple structure and low price. They are the most widely used motors in the world. Most of the global electricity generation is consumed by AC motors. Therefore, the energy efficiency of AC motors and reluctance motors is very important. Most of the AC motors and reluctance motors used in my country are inefficient motors with energy efficiency below level three. The energy efficiency of small-power AC motors is generally less than 80%, but even small AC motors with level one energy efficiency do not exceed 90%. Only high-power level one energy efficiency AC motors can achieve an efficiency of 97%, but they are difficult to promote and apply due to their high cost. The existing AC motors and reluctance motors are bulky and have low energy efficiency. The main reason is that the stator wire windings are open wire windings, which are originally There are defects in the design. In order to facilitate the installation of the rotor, the two ends of the wire winding are semi-circular to avoid the end face of the rotor. Therefore, the electromagnetic field of this wire winding is not closed, and the two ends are open electromagnetic fields, resulting in poor induction effect on the rotor. Secondly, because the wire winding needs to be supported by the iron core and enhance the induced magnetic field at the same time, the use density of the wire winding is limited. The adverse consequences of this open wiring method are: first, it greatly increases the eddy current iron loss of the iron core; second, it limits the use of wires, limits the reduction of wire resistance, and thus limits the motor power; third, the redundant wires at the two ends of the wire winding are almost half, which is equivalent to increasing the resistance copper loss by half; fourth, the redundant wires at the two ends of the wire winding are semicircular around the open rotor, forming a useless axial changing magnetic field at the two ends of the rotor, thereby generating unnecessary eddy current iron loss in the rotor core. Fifth, in order to avoid the adverse effects of too many redundant wires at both ends of the wire winding, the length of the rotor is usually much larger than the diameter. AC motors generally use a 50 Hz industrial frequency power supply. When the speed is limited, increasing the diameter of the rotor is the best way to increase the motor output power and power. Sixth, the best shape of the inductor is cylindrical, followed by square, and the worst is rectangular. The larger the ratio of width to thickness, the worse the inductance effect. The winding method of the existing AC motor is exactly the worst rectangle. In summary, in order to avoid the rotor, the wire winding of the existing AC motor has to be wound into a semicircular ring at both ends to form an open electromagnetic field. It also has to use an iron core stator to fix the wire winding, and use the iron core stator to compensate for the magnetic field loss of the open electromagnetic field. In summary, the root cause of a series of problems in the existing AC motor is that the wire winding is an open electromagnetic field. Originally, the perfect wire winding must be a closed electromagnetic field. What needs to be done is how to make the wire winding of the closed electromagnetic field bypass the output shaft of the rotor instead of bypassing the entire rotor.

[0027] The utility model adopts a parallelogram wire frame of a closed electromagnetic field. The current direction of the wire frame is along the axial direction and end face of the magnetic resistance body to form a closed induction magnetic field. The electromagnetic induction effect is increased by dozens of times, and the stator core can be abandoned. The wire frame is fixed by the casing. The wire frame covers the entire rotor magnetic resistance body, and only needs to avoid the shaft rod, rather than the end face of the entire rotor magnetic resistance body. The diameter of the rotor is equal to or greater than the height, and the comprehensive efficiency can reach 99%. The weight and volume can be reduced to about one tenth of the existing AC motor, and the process is simpler and the production cost is lower. As a new energy vehicle motor application, the rotation speed is several times that of the permanent magnet motor, and ultra-high-speed rotation can be achieved. The rotation speed can reach more than 60,000 revolutions per minute, the power is one thousand kilowatts, and the power density is several tens of kilowatts per kilogram.

[0036] Implementation 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in: a hexagonal closed reluctance motor, including a rotor 1, a housing 2, a wire frame 3, and a bearing 4, characterized in that: the rotor 1 includes a shaft 10 and a reluctance body 11, the shaft 10 is tightly connected to the reluctance body 11, the reluctance body 11 is coaxially mounted with the shaft 10, one end of the shaft 10 is used as a power output shaft, the reluctance body is a silicon steel laminated iron core with reluctance characteristics, the reluctance body is a silicon steel laminated iron core with two salient poles, axially twisted within 90 degrees, in a twisted surface twist shape, which can ensure power balance in any rotation direction, and there is a closed-loop conductor in the grooves of the two salient poles of the reluctance body, the closed-loop conductor is also in a twisted surface twist shape, and the closed-loop conductor is an aluminum conductor or a copper conductor, so that the electromagnetic induction force can be strengthened. The diameter of the reluctance body is equal to or greater than the height, which helps to greatly increase the power and power-to-weight ratio of the AC closed induction motor.

[0037] The housing 2 is a fixing member supporting the wire frame 3 and the rotor 1. The housing 2 is cylindrical or has a cylindrical structure, with a cover at one or both ends. There are bearing seats at the centers of the two ends of the housing 2. The shaft 10 of the rotor 1 is equipped with bearings 4. The bearings 4 are mounted in the bearing seats at the centers of the two ends of the housing 2. There are steps on the shaft 10 on both sides of the magnetic resistance body 11, or there are slots and springs to fix the position of the bearings 4. The wire frame 3 is arranged inside the housing 2. The housing 2 is cylindrical or has a cylindrical structure. The cylindrical structure means that the housing 2 has only the most basic cylindrical force-bearing frame and an open structure without a closed surface. The material of the housing 2 can be a combination of one or more materials, generally cast iron or aluminum alloy.

[0038] The wire frame 3 is a rectangular wire winding. The wire frame 3 has three phases, which are distributed along the circumference of the rotor at a certain angle. The wire frame 3 is sheathed with the magnetic resistance body 11. The current direction of the wire frame 3 surrounds the magnetic resistance body 11 along the axial direction and end surface to form a closed induction magnetic field. There is a rotation gap between the wire frame 3 and the magnetic resistance body 11. The gap between the three-phase wire frame 3 and the magnetic resistance body 11 is very small, so there is no need to use an additional stator core. The wire frame 3 is generally copper enameled wire or aluminum enameled wire, and the cross-section is round wire or flat wire. The wire frame 3 is solidified with epoxy resin to strengthen the structural stress.

[0039] The wire frame 3 has three phases, and the three-phase wire frames 3 cross each other in a star shape along the circumference of the rotor and are evenly distributed at 120 degrees. Each phase wire frame 3 is divided into two groups, and the two groups of wire frames 3 are distributed in parallel on the two sides of the shaft rod 10. The wire ends of the three-phase wire frames 3 are connected according to the star connection method of the three-phase asynchronous induction motor, or are connected according to the triangle connection method. The casing 2 is in the shape of a regular hexagonal cylinder, with a front cover and a rear cover. There are bearing seats at the centers of the two ends of the casing 2. The midlines of the six faces of the inner wall of the casing have axial convex strips 21. The width of the axial convex strips 21 is equal to or greater than the diameter of the shaft rod 10. The axial convex strips 21 are located between two adjacent groups of wire frames 3. The three-phase six groups of wire frames 3 are assembled into the regular hexagonal cylindrical casing 2, and are clamped and fixed by the six inner wall surfaces, which can play the same supporting role as the stator.

[0040] There are two installation modes for this motor: horizontal and vertical. When the installation mode is horizontal, the bottom surface of the casing 2 has a base frame, and the base frame has screw holes. When the installation mode is vertical, the front end of the casing 2 has a base frame, and the base frame has screw holes. The side of the casing 2 is provided with wire lead-out holes and screw holes, the back cover is provided with a wiring bridge and an insulating wire box, the outer surface of the casing is provided with heat sinks, and the heat sinks are axially distributed. The shaft extends from the back cover and is connected to a cooling fan, and the back cover is provided with a fan cover, or the back cover is provided with wire lead-out holes and screw holes, and the back cover is provided with a wiring bridge and an insulating wire box.

[0041] The wire frame 3 has three phases, U, V, and W. Each phase wire frame 3 has two groups, and each group has several wire frames. Each wire frame of the three phases, U, V, and W, is interlaced and set in a star shape along the periphery of the hexagonal stator 5. That is, after the U phase is wound around the first circle, the V phase is wound around the second circle, and then the W phase is wound around the third circle, and then the U phase is wound around the fourth circle, the V phase is wound around the fifth circle, and the W phase is wound around the sixth circle, and so on. The advantage of this is to eliminate the difference in induction intensity caused by the gap difference at the end surface of the U, V, and W three-phase wire frame 3.

[0042] When the conductor frame 3 is a three-phase multi-group, the electromagnetic field arrangement of the multi-group three-phase conductor frame 3 is a dipole magnetic field arrangement, a quadrupole magnetic field arrangement, a sextupole magnetic field arrangement, or an octupole magnetic field arrangement.

[0043] The closed reluctance motor has a position sensor, which includes one or more of an electromagnetic position sensor, a magnetic position sensor, and a photoelectric position sensor. The housing has an electromagnetic induction coil, or a Hall circuit, or a rotary transformer at the end of the shaft, or a magnetic encoder, or a photosensitive signal sensor. The current passes through the feedback of the position sensor and the control of the motor controller, so that the wire frame forms a rotating magnetic field to drive the reluctance body to rotate synchronously. Alternatively, the outer periphery of the reluctance body 11 is tightly covered with an aluminum tube sleeve to form a short-circuit ring. The length of the aluminum tube sleeve is equal to or greater than the length of the reluctance body 11. In this way, the asynchronous induction start can be directly performed with alternating current. When it is close to the natural frequency of the power supply, the reluctance body 11 will automatically resonate and synchronize with the power supply frequency. At this time, the rotor is synchronized with the power supply frequency. In this way, there is no need to use a position sensor and a motor controller.

[0044] The wire frame 3 is a parallelogram closed wire winding, which is different from the open winding of the existing motor wire winding, and the installation method is also different. The rotor of the existing motor can be directly installed in the sub-circular opening embedded with the wire winding stator, but the present motor needs to first put the three-phase wire frame 3 on the rotor, and then the wire frame 3 and the rotor 1 are installed in the casing 2 together and then fix their respective positions. The three-phase six-group wire frame 3 is fixed by the six faces and six axial convex strips 21 on the inner wall of the casing, and the rotor 1 is fixed in position by the bearing seats at the two ends of the casing. The size of the wire frame 3 is larger than the size of the magnetic resistance body 11 of the rotor 1, and a rotation gap is left between the two.

[0045] The operation of the three-phase AC closed reluctance motor is the same as that of the AC synchronous reluctance motor. When the symmetrically distributed three-phase conductor frame 3 is connected to the three-phase AC power supply, a symmetrical three-phase current will flow into the winding and generate a rotating magnetic field in the closed space. The magnetic field rotates along the inner circumference of the circular opening of the stator 5. When the magnetic field rotates, the silicon steel laminated core of the rotor 1 with magnetic resistance is dragged to rotate in the conductor frame 3.

[0046] Implementation 2: Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown in: a hexagonal closed reluctance motor, including a rotor 1, a casing 2, a wire frame 3, and a bearing 4, characterized in that: the rotor 1 includes a shaft 10 and a reluctance body 11, the shaft 10 is tightly connected to the reluctance body 11, the reluctance body 11 is coaxially mounted with the shaft 10, one end of the shaft 10 serves as a power output shaft, the reluctance body is a silicon steel laminated core with reluctance characteristics, the reluctance body is a silicon steel laminated core with two or more salient pole structures, and the diameter of the reluctance body is equal to or greater than the height, which helps to significantly increase the power and power-to-weight ratio of the AC closed induction motor.

[0110] The wire frame 3 has three phases, and the three-phase wire frame 3 is evenly distributed along the 60-degree equilateral triangle of the rotor circumference. The wire ends of the three-phase wire frame 3 are connected according to the star connection of the three-phase asynchronous induction motor, or are connected according to the triangle connection. The casing is an equilateral triangle cylinder with a front cover and a rear cover. There are bearing seats at the centers of the two ends of the casing. The three inner angles of the casing have fixed angles, and the fixed angles are in the shape of an inverted isosceles triangle rod. The three angles of the isosceles triangle rod are 30 degrees, 120 degrees, and 30 degrees respectively. The fixed angle is between two adjacent groups of wire frames. The three-phase three-group wire frame 3 is assembled into the triangular cylindrical casing 2, and is clamped and fixed by three inner wall surfaces and three fixed angles, and can play the same supporting role as the stator.

[0111] The casing 2 is composed of a triangular skeleton 22 and a triangular tube 23. The triangular skeleton 22 is composed of two equilateral triangular cover plates 24 and three isosceles triangular rods 25 or three rhombus rods. The three angles of the isosceles triangular rods are 30 degrees, 120 degrees, and 30 degrees respectively. The two equilateral triangular cover plates 24 have bearing seats in the centers, and the three corners of the equilateral triangular cover plates 24 have screw holes. The isosceles triangular rods 25 have screw holes in the centers of both ends, and the two equilateral triangular cover plates 24 and the three isosceles triangular rods 25 are connected by bolts.

[0112] There are two installation modes for this motor: horizontal and vertical. When the installation mode is horizontal, the bottom surface of the casing 2 has a base frame, and the base frame has screw holes. When the installation mode is vertical, the front end of the casing 2 has a base frame, and the base frame has screw holes. The side of the casing 2 is provided with wire lead-out holes and screw holes, the back cover is provided with a wiring bridge and an insulating wire box, the outer surface of the casing is provided with heat sinks, and the heat sinks are axially distributed. The shaft extends from the back cover and is connected to a cooling fan, and the back cover is provided with a fan cover, or the back cover is provided with wire lead-out holes and screw holes, and the back cover is provided with a wiring bridge and an insulating wire box.

[0113] The wire frame 3 has three phases, U, V, and W. Each phase wire frame 3 has two groups, and each group has several wire frames. Each wire frame of the three phases, U, V, and W, is interlaced and set in a star shape along the periphery of the hexagonal stator 5. That is, after the U phase is wound around the first circle, the V phase is wound around the second circle, and then the W phase is wound around the third circle, and then the U phase is wound around the fourth circle, the V phase is wound around the fifth circle, and the W phase is wound around the sixth circle, and so on. The advantage of this is to eliminate the difference in induction intensity caused by the gap difference at the end surface of the U, V, and W three-phase wire frame 3.

[0114] When the conductor frame 3 is a three-phase multi-group, the electromagnetic field arrangement of the multi-group three-phase conductor frame 3 is a dipole magnetic field arrangement, a quadrupole magnetic field arrangement, a sextupole magnetic field arrangement, or an octupole magnetic field arrangement.

[0115] The closed reluctance motor has a position sensor, which includes one or more of an electromagnetic position sensor, a magnetic position sensor, and a photoelectric position sensor. The housing has an electromagnetic induction coil, or a Hall circuit, or a rotary transformer at the end of the shaft, or a magnetic encoder, or a photosensitive signal sensor. The current passes through the feedback of the position sensor and the control of the motor controller, so that the wire frame forms a rotating magnetic field to drive the reluctance body to rotate synchronously. Alternatively, the outer periphery of the reluctance body 11 is tightly covered with an aluminum tube sleeve to form a short-circuit ring. The length of the aluminum tube sleeve is equal to or greater than the length of the reluctance body 11. In this way, the asynchronous induction start can be directly performed with alternating current. When it is close to the natural frequency of the power supply, the reluctance body 11 will automatically resonate and synchronize with the power supply frequency. At this time, the rotor is synchronized with the power supply frequency. In this way, there is no need to use a position sensor and a motor controller.

[0116] The wire frame 3 is a parallelogram closed wire winding, which is different from the open winding of the existing motor wire winding, and the installation method is also different. The rotor of the existing motor can be directly installed in the round mouth of the stator embedded with the wire winding, but the present motor needs to first put three arc-shaped stators 5 on the three-phase wire frame 3, and then install the rotor 1 into the round mouth of the assembled stator 5. The wire frame 3 and the stator are installed together with the rotor 1 in the casing 2 and then their respective positions are fixed. The three-phase wire frame 3 and the stator 5 are fixed by clamping the three inner wall surfaces and three fixed angles of the casing. The rotor 1 is fixed in position by the bearing seats at the two ends of the casing. The size of the round mouth of the stator 5 is larger than the size of the magnetic resistance body 11 of the rotor 1, and a rotation gap is left between the two.

[0117] The operation of the three-phase AC closed reluctance motor is the same as that of the AC synchronous reluctance motor. When the symmetrically distributed three-phase conductor frame 3 is connected to the three-phase AC power supply, a symmetrical three-phase current will flow into the winding and generate a rotating magnetic field in a closed space. The magnetic field rotates along the inner circumference of the stator 5 circular opening. When the magnetic field rotates, the silicon steel laminated core of the rotor 1 with magnetic resistance is dragged to rotate in the stator 5 circular opening.

[0118] The above-mentioned embodiments only describe several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be based on the attached claims.
