[0002] A permanent magnet synchronous motor is a synchronous motor that uses permanent magnets to generate a magnetic field. The speed of its rotor is consistent with the current frequency of the stator winding. The working principle of the permanent magnet synchronous motor is based on the interaction between the rotating magnetic field generated by the stator and the magnetic field generated by the permanent magnets on the rotor. Pre-magnetized permanent magnets are installed on the rotor. These permanent magnets can generate a strong magnetic field when rotating, thereby providing greater output torque.

[0029] Specifically, Figure 3 and Figure 4 As shown, the fixing sleeve 203 is provided with a plurality of heat dissipation holes 204 distributed in a ring shape, and both ends of the plurality of heat dissipation holes 204 extend to the outside of the fixing sleeve 203. The heat dissipation holes 204 are cylindrical structures. The opening of the heat dissipation holes 204 is conducive to reducing the weight of the fixing sleeve 203 and allowing air flow to pass through, thereby playing a role in heat dissipation.

[0030] Specifically, Figure 3 and Figure 4As shown, the embedded mechanism 3 includes a slot 301, and a plurality of groups of slots 301 distributed in a ring shape are arranged inside the fixed sleeve 203.

In addition, the two symmetrical second magnetic blocks 302 are a group, and the angle between the two symmetrical slots 301 is 45 degrees, which facilitates the better distribution of the magnetic field and facilitates the subsequent energy conversion.

[0031] Specifically, Figure 3 , Figure 4 and Figure 5 As shown, the abutment mechanism 4 includes a plurality of groups of annular and equidistantly distributed movable grooves 401 arranged inside the fixed sleeve 203, three equidistantly distributed movable grooves 401 form a group, and a plurality of groups of movable grooves 401 are respectively installed with a pressing block 403, and the bottom of the pressing block 403 is slidably connected with the inside of the movable groove 401 through a plurality of return springs 404, and the pressing block 403 is an inverted "Y" shaped structure, and the top of the pressing block 403 extends to the inside of the card slot 202 and abuts against the bottom of the first magnetic block 201, and the two ends of the bottom of the pressing block 403 extend to the inside of the slot 301 and abut against the second magnetic block 3 02 opposite sides contact, through the opening of the movable groove 401, it is convenient to install the pressing block 403, through the installation of the reset spring 404, it is convenient to reset the contact of the pressing block 403, through the insertion of the first magnetic block 201, it is convenient to contact multiple pressing blocks 403 in sequence, so that multiple pressing blocks 403 get rid of the contact of the reset spring 404 and slide down, which is convenient for the two ends of the bottom of the pressing block 403 to contact the center line of the opposite sides of the two second magnetic blocks 302, so that the first magnetic block 201 and the two second magnetic blocks 302 are installed firmly and stably without loosening.

[0032] Specifically, Figure 5As shown, rubber pads 406 are respectively installed at both ends of the bottom of the pressing block 403, and the bottom side of the rubber pad 406 is a toothed structure. The bottom of the rubber pad 406 contacts the second magnetic block 302. A plurality of guide rods 405 are vertically connected to the bottom of the pressing block 403. The plurality of guide rods 405 penetrate the reset spring 404 and are slidably connected inside the pressing block 403. The installation of the rubber pads 406 is conducive to increasing the friction between the bottom of the pressing block 403 and the second magnetic block 302, which plays a role in stabilizing the contact with the second magnetic block 302, and is conducive to the pressing block 403 not causing wear when squeezing the second magnetic block 302. The installation of the guide rods 405 is conducive to guiding the pressing block 403, and the guide rods 405 penetrate the reset spring 404, which plays a role in guiding and positioning the compression spring 407, and prevents the reset spring 404 from being squeezed and popped out.

[0033] Specifically, Figure 4 , Figure 5 and Figure 6 As shown, a protrusion 402 is installed on the top of the pressing block 403, and the bottom of the protrusion 402 extends into the inside of the pressing block 403. The bottom of the protrusion 402 is slidably connected to the inner side of the top of the pressing block 403 through a compression spring 407. The top of the protrusion 402 is a hemispherical structure, and the top of the protrusion 402 is in contact with the first magnetic block 201. The installation of the protrusion 402 and the top of the pressing block 403 facilitates the first magnetic block 201 to have a good contact with the protrusion 402, thereby realizing that the pressing block 403 is driven. The installation of the compression spring 407 makes the protrusion 402 and the inner side of the top of the pressing block 403 elastic, which facilitates the protrusion 402 to continue to slide in contact with the first magnetic block 201 after the bottom of the pressing block 403 is in stable contact with the second magnetic block 302, so that the first magnetic block 201 can be smoothly installed.

[0034] Specifically, Figure 1 and Figure 2As shown, the locking mechanism 5 includes a chuck 501, and two ends of the iron core 1 are respectively slidably connected with symmetrical chucks 501, and the opposite sides of the two chucks 501 are in conflict with the two ends of the fixed sleeve 203. The two ends of the plurality of first magnetic blocks 201 and the plurality of second magnetic blocks 302 are respectively in conflict with the opposite sides of the two chucks 501, and the two ends of the iron core 1 are respectively slidably connected with limiting sleeves 502, and the opposite ends of the two limiting sleeves 502 are in conflict with the two chucks 501. Sliding sleeves 503 are respectively installed at both ends of the iron core 1, and a conflicting spring 506 is connected between the sliding sleeve 503 and the limiting sleeve 502. The installation of the two chucks 501 is conducive to the fixing sleeve 20 The side walls at both ends are fitted together, thereby achieving abutment between the two ends of the plurality of first magnetic blocks 201 and the plurality of second magnetic blocks 302, so that the plurality of first magnetic blocks 201 and the plurality of second magnetic blocks 302 are stably installed and will not slip to both sides. Through the abutment of the two limiting sleeves 502, the stable abutment of the two chucks 501 is achieved. Through the installation of the two sliding sleeves 503, the two limiting sleeves 502 are facilitated to abut against each other, so that the chuck 501 is tightened. By installing a resistance spring 506 between the sliding sleeve 503 and the limiting sleeve 502, the limiting sleeve 502 is always in stable abutment with the chuck 501, so as to play a role of relaxation.

[0035] Specifically, Figure 1 and Figure 2 As shown, a plurality of annularly distributed blocks 504 are fixedly connected to the edges of the two chucks 501, one end of the plurality of blocks 504 extends to the side wall of the first magnetic block 201, and the bottom side of one end of the block 504 is in contact with the two second magnetic blocks 302. Through the installation of the plurality of blocks 504, after the two chucks 501 are in contact with the fixed sleeves 203, the plurality of blocks 504 can be in contact with the side walls of the plurality of first magnetic blocks 201, thereby playing a role in further stabilizing the engagement.

[0036] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, washers 507 are respectively installed at the opposite ends of the two limit sleeves 502, and the washers 507 are in contact with the side walls of the chuck 501. A plurality of positioning blocks 505 distributed in a ring are vertically connected to the opposite sides of the two chucks 501. One end of the positioning block 505 is engaged with the inside of the heat dissipation hole 204. Through the installation of the washers 507, a role of anti-slip is played between the limit sleeves 502 and the chuck 501. Through the engagement of the plurality of positioning blocks 505 with the plurality of heat dissipation holes 204, the chuck 501 is positioned, so that the chuck 501 will not rotate with the core 1.

[0037] Specifically, Figure 7 , Figure 8 and Fig. 9 As shown, the limiting mechanism 6 includes a bevel rack 601, and a group of bevel racks 601 are respectively installed on the outer walls at both ends of the iron core 1, and two symmetrical bevel racks 601 form a group. The inner sides of one end of the two sliding sleeves 503 are respectively rotatably connected to two symmetrical buckles 603 through a rotating shaft 604, and the rotating shaft 604 is fixedly connected to the buckle 603. A torsion spring 605 is connected between the two ends of the rotating shaft 604 and the inside of the sliding sleeve 503. One end of the buckle 603 is a "7"-shaped structure, and the bottom of one end of the buckle 603 conflicts with the bevel rack 601. The sharp teeth at the bottom of one end of the buckle 603 are in opposite directions to the sharp teeth of the bevel rack 601. A driving block 602 is installed on the top of the other end of the buckle 603, and the top side of the driving block 602 extends to the outside of the sliding sleeve 503. The driving block 602 is connected to the outer side of the sliding sleeve 503 by the buckle. 603 is slidably connected with the sliding sleeve 503. The buckle 603, driven by the torsion spring 605, keeps the bottom of one end of the buckle 603 in contact with the bevel rack 601 at all times. Since the sharp teeth at the bottom of one end of the buckle 603 are in opposite directions to the sharp teeth of the bevel rack 601, the buckle 603 cannot slide outward, thereby limiting the sliding sleeve 503. By pushing the sliding sleeve 503, the buckle 603 is swung upward by the bevel rack 601, so that the sliding sleeve 503 can slide forward but cannot slide backward. By pressing the two driving blocks 602, the driving blocks 602 drive the buckle 603 to rotate to get rid of the elastic force of the torsion spring 605, so that the buckle 603 is separated from the bevel rack 601, which facilitates the sliding sleeve 503 to release the limited sliding.

[0038] Specifically, Fig. 9 As shown, the driving block 602 is a triangular structure, and the top side of the driving block 602 is a toothed structure. The top side of the driving block 602 is flush with the outer wall of the sliding sleeve 503, which is conducive to the driving control of the driving block 602, realizes the swing of the buckle 603, and increases the friction with the hand, so that the driving of the driving block 602 does not slip.

[0039] Specifically, Figure 1 and Figure 3As shown, the lubrication mechanism 7 includes an oil delivery hole 701. An oil delivery hole 701 is provided at the center inside the iron core 1. One end of the oil delivery hole 701 extends to the outside of the iron core 1. Oil guiding holes 702 are respectively provided on the inner sides of both ends of the iron core 1. Both ends of the oil guiding holes 702 extend to the outside of the iron core 1. The two ends of the oil delivery hole 701 are vertically communicated with the centers of the two oil guiding holes 702. The oil delivery hole 701 and the two oil guiding holes 702 are distributed in the shape of a Chinese character 'tu' inside the iron core 1. The diameter of the oil guiding hole 702 is one-third of the diameter of the oil delivery hole 701. The opening of the oil delivery hole 701 facilitates the input of lubricating oil into the interior of the iron core 1 for storage. And through the diversion of the two oil guiding holes 702, a small amount of lubricating oil can be introduced to the outside of the iron core 1, facilitating the lubrication of the bearing.

[0040] When the present invention is in use, firstly, the fixing sleeve 203 and the iron core 1 are fixedly installed, which is convenient for installing the plurality of arc-shaped first magnetic blocks 201. The opening of the plurality of annular slots 202 equidistantly distributed facilitates the installation of the plurality of first magnetic blocks 201 at the specified position. The design of the slots 202 and the arc-shaped structures at both ends of the first magnetic blocks 201 facilitates the first magnetic block 201 to be inserted and engaged from one end of the slots 202, which plays a role of preventing the first magnetic block 201 from falling off and facilitating disassembly and assembly, and facilitates subsequent disassembly and maintenance. The opening of the heat dissipation holes 204 facilitates the weight reduction of the fixing sleeve 203 and allows airflow to pass through, which plays a role of heat dissipation. The opening of the plurality of slots 301 facilitates the insertion and engagement of the plurality of second magnetic blocks 302, thereby realizing the embedded installation of the plurality of second magnetic blocks 302. , plays a role in protecting the second magnetic block 302, and through the two symmetrical second magnetic blocks 302 as a group, and the angle between the two symmetrical second magnetic blocks 302 is 45 degrees, it is beneficial to better distribute the magnetic field evenly, and it is beneficial to the subsequent energy conversion. The opening of the movable groove 401 is beneficial to the installation of the pressure block 403, and the installation of the reset spring 404 is beneficial to the resistance and reset of the pressure block 403. Through the insertion of the first magnetic block 201, it is beneficial to successively resist multiple pressure blocks 403, so that multiple pressure blocks 403 get rid of the resistance of the reset spring 404 and slide down, which is beneficial for the two ends of the bottom of the pressure block 403 to resist the midline of the opposite sides of the two second magnetic blocks 302, so that the first magnetic block 201 and the two second magnetic blocks 302 are installed firmly and stably without loosening. The installation of rubber pad 406 is conducive to increasing the friction between the bottom of pressure block 403 and second magnetic block 302, which plays a role in stabilizing the resistance of second magnetic block 302 and is conducive to the pressure block 403 not causing wear when squeezing the second magnetic block 302. The installation of guide rod 405 is conducive to guiding the pressure block 403, and the guide rod 405 runs through the reset spring 404, which plays a role in guiding and positioning the compression spring 407, preventing the reset spring 404 from being squeezed and popped out. The installation of protrusion 402 and the top of pressure block 403 is conducive to the first magnetic block 201 to have a good resistance to protrusion 402, thereby realizing the driving of pressure block 403. The installation of compression spring 407 makes the protrusion 402 and the inner side of the top of pressure block 403 have elasticity. , after the bottom of the pressing block 403 is in contact with the second magnetic block 302 and is stable, the protrusion 402 can be contacted by the first magnetic block 201 and continue to slide, so that the first magnetic block 201 can be installed smoothly. Through the installation of the two chucks 501, it is convenient to fit the side walls of the fixing sleeve 203 at both ends, thereby achieving the contact between the two ends of the multiple first magnetic blocks 201 and the multiple second magnetic blocks 302, so that the multiple first magnetic blocks 201 and the multiple second magnetic blocks 302 are stably installed and will not slip to both sides. Through the contact of the two limiting sleeves 502, the contact of the two chucks 501 is stable. Through the installation of the two sliding sleeves 503, it is convenient to contact the two limiting sleeves 502 to achieve the fastening of the chuck 501. By installing the contact spring 506 between the sliding sleeve 503 and the limiting sleeve 502,The limiting sleeve 502 is always kept in contact and stability with the chuck 501, which plays a role of relaxation. Through the installation of multiple clamping blocks 504, after the two chucks 501 are in contact with the fixed sleeve 203, the multiple clamping blocks 504 can contact the side walls of the multiple first magnetic blocks 201, which plays a role of further clamping and stabilizing. Through the installation of gaskets 507, the limiting sleeve 502 and the chuck 501 are prevented from slipping. Through the clamping of multiple positioning blocks 505 with the inside of multiple heat dissipation holes 204, the chuck 501 is positioned so that the chuck 501 will not rotate with the iron core 1. Symmetrical buckles 603 are installed on the two sliding sleeves 503. Under the drive of the torsion spring 605, the bottom of one end of the buckle 603 is always kept in contact with the bevel rack 601. Because the sharp teeth at the bottom of one end of the buckle 603 are in the same direction as the sharp teeth of the bevel rack 601 On the contrary, the buckle 603 cannot slide outward, which plays a role in limiting the sliding sleeve 503. By pushing the sliding sleeve 503, the buckle 603 is resisted by the bevel rack 601 and swings upward, so that the sliding sleeve 503 can slide forward but cannot slide backward. By pressing the two driving blocks 602, the driving block 602 drives the buckle 603 to rotate away from the elastic force of the torsion spring 605, so that the buckle 603 is separated from the bevel rack 601, which is convenient for the sliding sleeve 503 to release the limited sliding, which is convenient for driving and controlling the driving block 602, realizing the swing of the buckle 603, and increasing the friction with the hand, so that the driving block 602 does not slip. The opening of the oil delivery hole 701 is convenient for the lubricating oil to be input into the iron core 1 for storage, and the two oil guide holes 702 are used to guide the lubricating oil so that a small amount of lubricating oil can be introduced into the outside of the iron core 1, which is convenient for lubricating the bearing.
