Description

Technical Field

[0001] The utility model relates to the technical field of reluctance motors, in particular to a permanent magnet electromagnetic hybrid switched reluctance motor. Background Art

[0002] There are two main types of existing reluctance motors: permanent magnet synchronous reluctance motor and switched reluctance motor. The main difference between the two motors is whether there are permanent magnets in the mover (or rotor). The one with permanent magnets is a permanent magnet synchronous motor. The power factor of the permanent magnet synchronous reluctance motor is higher, while the mover part of the switched reluctance motor has no permanent magnets and a simple structure. Especially for linear switched reluctance motors in long lines, the mover (line) part has no permanent magnets, low cost, no electromagnetic interference, and good maintainability.

[0003] Adding permanent magnets can save excitation energy consumption, but there are currently few designs that add permanent magnets to the stator part of the switched reluctance motor. The reason is that the magnetic poles of the stator part are symmetrically distributed along the direction of movement. If permanent magnets are added to the magnetic poles, the forces generated by the permanent magnets on each phase of the motor will cancel each other out, and the net force will be zero. This results in the permanent magnets in the stator part not only playing an excitation role and affecting the equivalent inductance, but also failing to effectively reduce the energy consumption of the reluctance motor. In the prior art, the design of adding permanent magnets to the stator part of the switched reluctance motor is only to improve the performance of the motor torque ripple, and cannot improve the efficiency of the motor.

[0004] If permanent magnet material is added to the stator of the switched reluctance motor, and the permanent magnet in a phase that is in working state can be activated, while the permanent magnet in other phases that are not in working state can be inactivated, this can not only maintain the simple structure of the rotor part without permanent magnet, but also effectively reduce the energy consumption of the motor. In order to achieve this effect, it is necessary to control the shutdown of the magnetic circuit like controlling the current. However, controlling the magnetic field is more difficult than controlling the electric field. In the current application of permanent magnets, it is impossible to achieve functions such as magnetic circuit conduction, magnetic circuit shutdown, and magnetic field short circuit like controlling the circuit current.

[0037] The utility model provides a permanent magnet electromagnetic hybrid switched reluctance motor, in which a permanent magnet part and a magnetic conduction part are arranged on the magnetic pole of the stator part of the switched reluctance motor, so as to achieve the purpose of adding permanent magnet excitation to the stator part of the switched reluctance motor and reducing the energy consumption of the motor.

[0038] The permanent magnet electromagnetic hybrid switched reluctance motor comprises a mover and a stator. The mover comprises a mover yoke and mover teeth, both of which are made of magnetic conductive materials. The mover teeth are arranged on the mover yoke at equal intervals to form the mover of the motor.

[0039] The stator includes at least three phase units, each of which includes two magnetic poles, an iron core, one or two windings (one winding is wound on the iron core, and two windings are wound on two magnetic poles respectively), and a permanent magnet part and a magnetic flow guide part are arranged on each magnetic pole surface. The magnetic poles, iron core, and flow guide part of the phase unit are made of magnetic conductive materials, and the winding is made of conductive materials. The magnetic poles of the permanent magnet parts on the two magnetic poles of the phase unit are in opposite directions, and the flow guide part is arranged according to the structure of the permanent magnet part.

[0040] When the winding is not energized and electromagnetic excitation is not added, under the magnetic conduction of the magnetic permeation part, the magnetic field generated by the permanent magnet part will mostly form a short-circuit magnetic path along the permanent magnet, magnetic permeation fluid, and magnetic poles. When the winding is energized and electromagnetic excitation is added, the magnetic field generated by the permanent magnet part will mostly form a working magnetic path along the stator core, stator magnetic poles, and mover.

[0041] The permanent magnet electromagnetic hybrid switched reluctance motor is conducive to the operation of the minimum magnetic resistance principle. Current is passed through the phase winding that is misaligned with the rotor teeth, and the magnetic field generated by the winding current and the magnetic field generated by the permanent magnet work together to drive the rotor to operate. Since the magnetic field generated by the winding current will change the magnetic circuit of the permanent magnet part, the permanent magnet part of the energized phase unit can generate an effective working magnetic circuit, while the magnetic field generated by the permanent magnet part of the phase unit without energization runs along the short-circuit magnetic circuit, which has little effect on the movement of the motor rotor.

[0042] The utility model is realized by configuring a permanent magnet part and a magnetic permeation part on the stator magnetic poles on the basis of the existing switched reluctance motor, so it can be implemented on both the existing rotary switched reluctance motor and the linear switched reluctance motor. For example, by adding a permanent magnet part and a magnetic permeation part to the stator of a three-phase six-pole linear switched reluctance motor, a three-phase six-pole / four-pole rotary switched reluctance motor or a four-phase eight-pole / six-pole rotary switched reluctance motor, a permanent magnet electromagnetic hybrid three-phase six-pole linear switched reluctance motor, a three-phase six-pole / four-pole rotary switched reluctance motor or a four-phase eight-pole / six-pole rotary switched reluctance motor with lower energy consumption can be formed.

[0043] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0044] Example 1

[0045] like Figure 1 As shown, a permanent magnet electromagnetic hybrid three-phase six-pole linear switched reluctance motor includes a stator and a mover. The mover is the same as the existing motor, and has a structure in which the mover teeth are arranged at equal intervals.

[0046] The stator includes three phase units, namely, phase A unit, phase B unit and phase C unit. The configurations of the phase units are the same, and each phase unit includes a winding, an iron core, a magnetic pole, a permanent magnet, and a magnetic permeable fluid.

[0047] The phase units are arranged in ABC order, the mover teeth are directly opposite to the magnetic poles of the A-phase unit, and are offset with the B-phase unit and the C-phase unit, with the offset being 2 / 3 of the tooth width.

[0048] Take the A phase unit as an example. Figure 2 As shown, the permanent magnets arranged on the two magnetic poles of the phase unit have opposite polarities, and the magnetic field generated when the A phase winding is energized needs to be in the same direction as the magnetic field of the permanent magnet on the phase magnetic pole. Figure 3 As shown in , when the winding of the phase unit is not energized, most of the magnetic field generated by the permanent magnet forms a short-circuit magnetic path along the permanent magnet, the magnetic permeability fluid, and the magnetic pole. Figure 4 As shown, when the winding of the phase unit is energized and electromagnetic excitation is added, most of the magnetic field generated by the permanent magnet forms a working magnetic circuit along the stator core, stator poles, and mover.

[0049] According to the working principle of the switched reluctance motor, taking the motor rotor moving to the right as an example, Figure 5 At the position shown, the B-phase winding and the rotor teeth form a dislocation relationship that conforms to the rightward movement, so only the B-phase winding is energized. After running 2 / 3 of the tooth width, it reaches Figure 6 At the position shown, only the C phase winding is energized. After running 2 / 3 of the tooth width, it reaches Figure 7 At the position shown, only the A-phase winding is energized, and after running 2 / 3 of the tooth width, a movement cycle is completed. The phase change sequence of a motor working cycle is BCAB. By energizing in this order, the motor rotor can move to the right all the time. If it wants to move to the left, it can be energized in the phase change sequence of CABC.

[0050] During the operation of the motor, the magnetic circuit of the permanent magnet of the un-energized phase unit mainly passes through the permanent magnet, the magnetic permeability fluid and the magnetic pole, and has little effect on the movement of the motor.

[0051] The specific dimensions of this embodiment are shown in Table 1.

[0052] Table 1 Dimensional parameters of permanent magnet electromagnetic hybrid switched reluctance motor

[0054] Table 2 Driving force of switched reluctance motor

[0055]

[0056] Taking 2mm displacement as the step length, the motor rotor moves 2 / 3 of the length of a tooth. With the same number of turns, a forward current of 4A is passed through the reluctance motor without permanent magnets, and a forward current of 2.8A is passed through the reluctance motor with permanent magnets. The horizontal thrust of the reluctance motors with and without permanent magnets during movement is obtained through finite element simulation. The horizontal thrust is the driving force of the motor, as shown in Table 2.

[0057] From Table 2, it can be seen that the pure electromagnetic switched reluctance motor without permanent magnets can provide a maximum driving force of 152.83N, and the switched reluctance motor with permanent magnets and magnetic permeability fluid can provide a maximum driving force of 168.65N. According to the power formula P = I 2 It can be seen from R that the energy consumption of the reluctance motor without permanent magnets is at least twice the energy consumption of the permanent magnet electromagnetic hybrid switched reluctance motor of the utility model.

[0058] In the utility model, the arrangement of the permanent magnet part and the magnetic conduction part can be appropriately adjusted so that most of the magnetic field generated by the permanent magnet part forms a short-circuit magnetic circuit along the permanent magnet part, the magnetic conduction part and the magnetic pole.

[0059] For example, the permanent magnet part can be composed of a single permanent magnet, with two magnetically conductive fluids attached to the left and right sides of the permanent magnet, or two magnetically conductive fluids attached to the front and rear sides of the permanent magnet, or the permanent magnet can be enclosed in front, back, left and right of the permanent magnet, all of which can form a short-circuit magnetic circuit.

[0060] In a preferred solution, the permanent magnet part includes a plurality of permanent magnets, the magnetic permeability part includes a plurality of magnetic permeability fluids, and the permanent magnets and the magnetic permeability fluids are alternately attached. Figure 1 As shown, three permanent magnets are arranged on a magnetic pole face of a phase unit, and are alternately attached to two magnetic permeable fluids. Figure 8 As shown, two permanent magnets are arranged on a magnetic pole surface of the phase unit, and after being alternately bonded with a magnetic permeability fluid, two magnetic permeability fluids are arranged on the front and rear sides to form an "I"-shaped magnetic permeability portion.

[0061] Figure 1 and Figure 5 The direction in which the permanent magnets and the magnetic permeability fluid are alternately attached is arranged in accordance with the direction of motion of the mover, so that the short-circuit magnetic circuit formed is better. The direction in which the permanent magnets and the magnetic permeability fluid are alternately attached can also be arranged in a direction other than the direction of motion of the mover, as long as most of the magnetic field generated by the permanent magnets can form a short-circuit magnetic circuit along the permanent magnets, the magnetic permeability fluid, and the magnetic poles.

[0062] Example 2

[0063] Since adding permanent magnet parts and magnetic permeability parts can reduce the energy consumption of the motor, it is beneficial to reduce the volume of the stator of the switched reluctance motor when the energy consumption is the same during the design of the motor. Fig. 9As shown, the mover remains unchanged, and the phase unit of the stator is adjusted to form a compact permanent magnet electromagnetic hybrid three-phase six-pole linear switched reluctance motor. In this embodiment, one magnetic pole of the A phase unit, the B phase unit, and the C phase unit is arranged in sequence, and the other magnetic pole is also arranged in sequence. The two magnetic poles of the A phase unit are aligned with the mover teeth, the two magnetic poles of the B phase unit are offset to the left by 2 / 3 of the tooth width from the mover teeth, and the two magnetic poles of the C phase unit are offset to the right by 2 / 3 of the tooth width from the mover teeth. The permanent magnet polarity directions arranged on the two magnetic poles of the A phase unit, the B phase unit, and the C phase unit are opposite. In this embodiment, the first magnetic poles of the A phase unit, the B phase unit, and the C phase unit, that is, A1, B1, C1, and the second magnetic poles, that is, A2, B2, C2, the permanent magnet polarity directions arranged on them are NSNSNS, and can also be arranged as NNNSSS, as long as the permanent magnet polarity directions arranged on the two magnetic poles of the same phase unit are opposite, the winding of the phase unit can form a working magnetic circuit after being energized.

[0064] Example 3

[0065] The working principle of the rotary switched reluctance motor is the same as that of the linear switched reluctance motor, except that the structures of the stator and the mover are different. If the circular stator and mover (i.e., the rotor) of the rotary switched reluctance motor are pulled apart into a straight line, it can be regarded as a linear switched reluctance motor. Therefore, adding permanent magnets and magnetic conduction parts to the magnetic poles of the rotary switched reluctance motor can also reduce the energy consumption of the motor. Fig.10 , a permanent magnet electromagnetic hybrid three-phase rotary switched reluctance motor, the arrangement of its permanent magnet part and magnetic conduction part can refer to the aforementioned permanent magnet electromagnetic hybrid linear switched reluctance motor.

[0066] Example 4

[0067] like Fig.11 , a permanent magnet electromagnetic hybrid four-phase rotary switched reluctance motor, the arrangement of its permanent magnet part and magnetic conduction part can also refer to the aforementioned permanent magnet electromagnetic hybrid linear switched reluctance motor.
