Description

Technical Field

[0001] The present invention relates to the technical field of motors, and particularly to a disassembled magnetic isolation permanent magnet synchronous motor and a juicer. Background Art

[0002] A permanent magnet synchronous motor is a motor based on the principle of synchronous movement of magnetic fields. It generally includes a stator, a reinforced rotor rod, and windings. When the stator windings are excited by an alternating current power supply, a rotating magnetic field is generated, and the permanent magnets on the reinforced rotor rod are synchronously rotated under the action of the stator magnetic field. This synchronous rotation enables the motor to convert electrical energy into mechanical energy more efficiently and has good speed regulation performance. The permanent magnet synchronous motor has the characteristic of high efficiency, which means that under the same input power, it can output more mechanical power, thereby reducing energy loss. In a juicer, a high-efficiency motor can drive the blade to rotate faster, improve the juicing speed, and reduce power consumption at the same time, achieving the purpose of energy saving.

[0003] Among them, the patent with the publication number CN219779870U discloses a permanent magnet synchronous motor, belonging to the technical field of motors. This permanent magnet synchronous motor includes a reinforced rotor rod. The reinforced rotor rod includes a reinforced rotor rod iron core stacked by silicon steel sheets. The reinforced rotor rod iron core has an installation groove for permanent magnets and an outer magnetic isolation bridge located on the outer edge of the reinforced rotor rod iron core. The shape of the outer magnetic isolation bridge in the axial projection of the reinforced rotor rod iron core is corrugated.

[0004] When this structure is in use, by making the thickness of the outer magnetic isolation bridge thinner on the permanent magnet synchronous motor, the magnetic resistance is increased and the magnetic leakage is reduced. The air gap between the outer magnetic isolation bridge reinforced rotor rod and the stator is uneven, making the back electromotive force waveform of the motor a sine wave and the torque ripple smaller, realizing the stable operation of the motor. However, when this structure is in use, it is not easy to gather the magnetic field together, and it is also easy to cause uneven magnetic field distribution, resulting in lower precise control of its speed, torque, and position. Summary of the Invention

[0005] The present invention provides a disassembled magnetic isolation permanent magnet synchronous motor and a juicer, aiming to solve the problems proposed in the above background art.

[0006] The present invention is implemented as follows. The present invention provides the following technical solution: A disassembled magnetic isolation permanent magnet synchronous motor includes a housing, and a deployment component is arranged on the housing.

[0007] The deployment component includes a lining arranged in the housing. A gasket ring is arranged in the middle of the lining. A plurality of magnetic force pieces are distributed on the inner wall of the gasket ring, and a partition groove is formed between each adjacent two magnetic force pieces.

[0008] A backing plate is provided in the middle of the cushion ring. One side of the backing plate is provided with a reinforced magnetic focusing support cone cover. The vertical cross-sectional shape of the reinforced magnetic focusing support cone cover is conical, and a number of dislocation openings are distributed on the outer side of the reinforced magnetic focusing support cone cover. Connecting blocks are embedded in multiple said dislocation openings, and a number of windings are provided on each said connecting block.

[0009] A slip ring is rotatably connected in the middle of the reinforced magnetic focusing support cone cover. One end of the slip ring is fixedly provided with a reinforced rotor rod body. One end of the inner lining is provided with a magnetic conduction cylinder. One end of the magnetic conduction cylinder is provided with a docking plate. The magnetic conduction cylinder and the docking plate both penetrate through the housing and extend to the outside of the housing. A clamping plate is installed on the outside of the housing through bolts. A controller for controlling the magnitude of the current is installed on the clamping plate through bolts. Both ends of the clamping plate are inserted with slide rods, and slide sleeves are sleeved on the outer sides of the respective slide rods. The slide sleeves are slidably connected to the slide rods. Electric telescopic rods are provided at both ends of the controller. The electric telescopic rods are installed on the clamping plate through bolts, and the output ends of the respective electric telescopic rods extend to the corresponding slide sleeves.

[0010] It can be seen that in the above technical solution, the current is transmitted through the shunt coil, so that the current is distributed on each stator winding plate and generates a current, forming a magnetic field required for the rotation of the reinforced rotor rod body. The magnetic force sheet is used to enhance the magnetic field intensity, and the inner lining is used for shielding to avoid magnetic leakage, thereby improving the efficiency and stability of the motor. Moreover, each connecting block and winding are distributed on the reinforced magnetic focusing support cone cover, so that the magnetic fields generated by the connecting block and the winding interact with the magnetic field formed by the stator winding plate, driving the rotation of the reinforced rotor rod body. At the same time, through the conical cross-section of the reinforced magnetic focusing support cone cover, the magnetic field can be more effectively gathered on the axis line. Gathering the magnetic field on the axis line can maximize the utilization of magnetic energy, reduce the leakage and interference of the magnetic field, make the magnetic field act on the housing evenly and stably, reduce vibration and noise, improve the running smoothness of the motor, and thus improve the efficiency of the motor. This means that under the same input power, the motor can output more mechanical power.

[0011] Clamping arms are installed on both said slide sleeves through bolts. A magnetic conduction block is provided on the clamping arm. The vertical cross-sectional shape of the magnetic conduction block is arc-shaped. A groove plate is provided between the two magnetic conduction blocks. The groove plate covers the outside of the inner lining. The groove plate is installed on the housing through bolts. A constraint cylinder is provided in the middle of the groove plate. One end of the constraint cylinder is provided with an extension cylinder. The constraint cylinder and the extension cylinder are both located in the middle of the cushion ring. A number of stator winding plates are distributed between the inner lining and the cushion ring, and a shunt coil is clamped on each said stator winding plate.

[0012] It can be seen that in the above technical solution, the electric telescopic rod drives the sliding sleeve to slide on the sliding rod, and then the clamping arm drives the magnetic conduction block to displace, so that the magnetic conduction block can approach or move away from the constraint cylinder, realizing the function of controlling its magnetic field, increasing the direct-axis demagnetizing current component of the motor, and reducing the quadrature-axis current component, so as to weaken the air-gap synthesized magnetic field and thus increase the motor speed.

[0013] A juicer, comprising the disassembled magnetic isolation permanent magnet synchronous motor as described above, including a juicer main body covering the outside of the housing. A control button board is arranged on the juicer main body, and the control button board is electrically connected to the controller. A juicing cylinder is arranged on the top of the magnetic conduction block, and one end of the reinforced rotor rod extends to the bottom of the inner cavity of the juicing cylinder.

[0014] The present invention has the following advantages:

[0015] In the present invention, the controller supplies three-phase symmetrical current to the shunt coil. The current is transmitted through the shunt coil, so that the current is distributed on each stator winding board and generates current, forming a magnetic field required for the rotation of the reinforced rotor rod, making the magnetic field act on the reinforced rotor rod uniformly and stably, and avoiding the unstable rotation of the reinforced rotor rod caused by uneven magnetic field.

[0016] Through the conical cross-section of the reinforced magnetic concentrating support cone cover of the present invention, the magnetic field can be more effectively concentrated on the axis line. Concentrating the magnetic field on the axis line can maximize the utilization of magnetic energy, reduce the leakage and interference of the magnetic field, make the magnetic field act on the reinforced rotor rod uniformly and stably, reduce vibration and noise, improve the running stability of the motor, and thus improve the efficiency of the motor, which means that the motor can output more mechanical power under the same input power.

[0017] When the rotational speed of the reinforced rotor rod approaches its limit value in the present invention, in order to further expand the speed regulation range, the electric telescopic rod drives the sliding sleeve to slide on the sliding rod, and then the clamping arm drives the magnetic conduction block to displace, so that the magnetic conduction block can approach or move away from the constraint cylinder, realizing the function of controlling its magnetic field, increasing the direct-axis demagnetizing current component of the motor, and reducing the quadrature-axis current component, so as to weaken the air-gap synthesized magnetic field and thus increase the motor speed.

[0018] In summary, the overall design is simple and the structure is reasonable. Through the coordinated use of various structures, the current is transmitted through the shunt coil, causing the current to be distributed on each stator winding board and generating a current, forming a magnetic field required to strengthen the rotation of the rotor rod. This enables the magnetic field to act on the strengthened rotor rod evenly and stably, preventing unstable rotation of the strengthened rotor rod caused by uneven magnetic fields. Through the conical cross-section of the strengthened magnetic-concentrating support cone cover, the magnetic field can be more effectively concentrated on the axis line. Concentrating the magnetic field on the axis line can maximize the utilization of magnetic energy, reduce magnetic field leakage and interference, enable the magnetic field to act on the strengthened rotor rod evenly and stably, reduce vibration and noise, improve the running stability of the motor, and thus improve the efficiency of the motor. This means that under the same input power, the motor can output more mechanical power. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] As shown in the attached Figures 1-10 A disassembled magnetic isolation permanent magnet synchronous motor. Through the deployment component provided on the housing 1 and the corresponding cooperation of each structure, the current is transmitted through the shunt coil 26, so that the current is distributed on each stator winding plate 25 and generates a current, forming a magnetic field required for the rotation of the enhanced rotor rod 12. The magnetic field acts on the enhanced rotor rod 12 uniformly and stably, avoiding unstable rotation of the enhanced rotor rod 12 caused by uneven magnetic field. Through the conical cross-section of the enhanced magnetic focusing support cone cover 7, the magnetic field can be more effectively gathered on the axis line. Gathering the magnetic field on the axis line can maximize the utilization of magnetic energy, reduce magnetic field leakage and interference, make the magnetic field act on the enhanced rotor rod 12 uniformly and stably, reduce vibration and noise, improve the running stability of the motor, and thus improve the efficiency of the motor. This means that under the same input power, the motor can output more mechanical power, and the specific structural settings of the components are as follows.

[0033] The deployment component includes an inner lining 2 provided in the housing 1. A gasket ring 3 is provided in the middle of the inner lining 2. A plurality of magnetic force pieces 4 are distributed on the inner wall of the gasket ring 3, and a dividing groove 5 is formed between each adjacent two magnetic force pieces 4;

[0034] A spacer ring 3 is provided with a backing plate 6 in the middle. One side of the backing plate 6 is provided with a reinforced magnetic focusing support cone cover 7. The vertical cross-sectional shape of the reinforced magnetic focusing support cone cover 7 is set as a cone, and a number of dislocation openings 8 are distributed on the outer side of the reinforced magnetic focusing support cone cover 7.

A clamping plate 15 is installed on the outside of the housing 1 through bolts. A controller 16 for controlling the magnitude of the current is installed on the clamping plate 15 through bolts. Both ends of the clamping plate 15 are plugged with slide rods 17, and a slide sleeve 19 is sleeved on the outside of each of the slide rods 17. The slide sleeve 19 is slidably connected with the slide rod 17. Electric telescopic rods 18 are provided at both ends of the controller 16. The electric telescopic rods 18 are installed on the clamping plate 15 through bolts, and the output ends of each of the electric telescopic rods 18 extend to the corresponding slide sleeve 19.

[0036] Clamping arms 20 are installed on both of the slide sleeves 19 through bolts. A magnetic conduction block 21 is provided on the clamping arm 20. The vertical cross-sectional shape of the magnetic conduction block 21 is set as an arc. A groove plate 22 is provided between the two magnetic conduction blocks 21. The groove plate 22 covers the outside of the inner liner 2. The groove plate 22 is installed on the housing 1 through bolts. A constraint cylinder 23 is provided in the middle of the groove plate 22. One end of the constraint cylinder 23 is provided with an extension cylinder 24. The constraint cylinder 23 and the extension cylinder 24 are both located in the middle of the spacer ring 3. A number of stator winding plates 25 are distributed between the inner liner 2 and the spacer ring 3, and a shunt coil 26 is clamped on each of the stator winding plates 25.

[0037] A juicer includes the above-mentioned disassembled magnetic isolation permanent magnet synchronous motor, and includes a juicer main body 27 covering the outside of the housing 1. A control button board 28 is provided on the juicer main body 27, and the control button board 28 is electrically connected to the controller 16. A juicing cylinder 29 is provided on the top of the magnetic conduction block 21. One end of the reinforced rotor rod body 12 extends to the bottom of the inner cavity of the juicing cylinder 29.

[0038] During use according to the above structure, when the device is in use, the user can add food in the juicing cylinder 29 and control the controller 16 to start through the control button board 28, so that the reinforced rotor rod body 12 can rotate, which is easy to juice the food in the juicing cylinder 29.

[0039] When the motor is stationary, the controller 16 passes a three-phase symmetrical current to the shunt coil 26 through a wire. The current is transmitted through the shunt coil 26, so that the current is distributed on each stator winding plate 25 and generates a current, forming a magnetic field required for the rotation of the reinforced rotor rod body 12.

[0041] Meanwhile, through the conical cross-section of the reinforced magnetic concentrating support conical cover 7, the magnetic field can be more effectively concentrated on the axis line. Concentrating the magnetic field on the axis line can maximize the utilization of magnetic energy, reduce magnetic field leakage and interference, enabling the magnetic field to act on the reinforced rotor rod 12 uniformly and stably, reducing vibration and noise, improving the running smoothness of the motor, and thus enhancing the efficiency of the motor. This means that at the same input power, the motor can output more mechanical power.

[0042] And when the rotational speed of the reinforced rotor rod 12 approaches its limit value, in order to further expand the speed regulation range, the electric telescopic rod 18 drives the sliding sleeve 19 to slide on the sliding rod 17, and then the clamping arm 20 drives the displacement of the magnetic conduction block 21, enabling the magnetic conduction block 21 to approach or move away from the constraint cylinder 23, realizing the function of controlling its magnetic field, increasing the direct-axis demagnetizing current component of the motor, and reducing the quadrature-axis current component to weaken the air-gap resultant magnetic field, thereby increasing the motor speed.

[0043] Different from the prior art, the present application discloses a disassembled magnetic isolation permanent magnet synchronous motor. Through the corresponding cooperation of each structure, the current is transmitted through the shunt coil 26, causing the current to be distributed on each stator winding plate 25 and generating a current to form the magnetic field required for the rotation of the reinforced rotor rod 12, enabling the magnetic field to act on the reinforced rotor rod 12 uniformly and stably, avoiding unstable rotation of the reinforced rotor rod 12 caused by uneven magnetic field. Through the conical cross-section of the reinforced magnetic concentrating support conical cover 7, the magnetic field can be more effectively concentrated on the axis line. Concentrating the magnetic field on the axis line can maximize the utilization of magnetic energy, reduce magnetic field leakage and interference, enabling the magnetic field to act on the reinforced rotor rod 12 uniformly and stably, reducing vibration and noise, improving the running smoothness of the motor, and thus enhancing the efficiency of the motor.
