Description

Technical Field

[0001] The invention belongs to the technical field of permanent magnet motors, and in particular relates to a permanent magnet motor with good heat dissipation performance. Background Art

[0002] A permanent magnet motor is a motor that uses permanent magnets to generate a magnetic field. It does not require an external excitation coil or current to generate a magnetic field. Its working principle is based on the law of electromagnetic induction and the Lorentz force law. There are many types of permanent magnet motors, including permanent magnet synchronous motors, permanent magnet DC motors, and permanent magnet brushless DC motors. These types of motors differ in structure and working principles, but all use the magnetic field generated by permanent magnets to realize the function of the motor.

[0003] The permanent magnet motors currently on the market have the following problems when applied:

[0004] 1. When a traditional permanent magnet motor is actually used, the internal structure of the motor body will usually emit heat after a long period of use. Since the higher the temperature, the more likely it is to affect the efficiency of the motor body, the heat dissipation performance is weaker during use;

[0005] 2. When installing most permanent magnet motors, fasteners are often needed to install the motor body. Since the mounting hole structure on the top of the support seat is fixed, once it is found that it is not aligned with the empty space on the mounting surface during installation, it needs to be disassembled and cleaned and reassembled. Therefore, it is inconvenient to adjust the position of the mounting structure during installation.

[0006] 3. When most permanent magnet motors are used, the motor body and the mounting surface are usually supported directly only through the support base structure. Such support is weak and the strength is not high, so the supporting force is not strong when used. Summary of the invention

[0007] The present invention aims to provide a permanent magnet motor with good heat dissipation performance to solve the technical problems raised in the background technology.

[0008] To achieve the above-mentioned purpose, the specific technical scheme of the present invention is as follows: a permanent magnet motor with good heat dissipation performance, comprising a motor body and a support base, the bottom of the motor body is fixedly connected to the support base, a stirring shaft is provided on the side of the motor body, a placement rack is installed on the outside of the motor body, an exhaust device is installed on the top of the placement rack, a blowing device is installed on the side of the placement rack, the blowing device is symmetrically distributed, a frame is provided on the side of the placement rack, a heat sink is installed inside the frame, and heat sink fins are provided on the outside of the heat sink, and the heat sink fins are equidistantly distributed.

Before the motor body is used, the placement rack is installed on the top of the support seat by fasteners. After starting the motor body, since the blowing device is tilted, the blowing device will blow wind to the exhaust device, and the exhaust device will discharge all the internal heat. Then the heat sink and the heat fins absorb the heat and discharge it to the outside. In this way, the heat dissipation structure installed on the outside of the placement rack and the frame is used in conjunction with each other, and the heat dissipation performance is good when in use;

[0017] 2.

[0018] 3. This kind of permanent magnet motor with good heat dissipation performance can improve the overall supporting strength of the bottom of the support seat by installing a base plate on the inner side of the support seat, installing a reinforcing plate and a reinforcing block on the top of the base plate, and embedding a gasket inside the reinforcing block. Before installing the motor body, the gasket is installed on the inner side of the reinforcing block, and the staff splices the reinforcing plate and the reinforcing block, and installs the supporting structure inside the base plate. In this way, when installing the motor, the supporting structure and the supporting seat structure cooperate with each other, and the effect of using the support seat is stronger.

[0044] The working principle of the permanent magnet motor with good heat dissipation performance: when using the equipment, the motor body 1 needs to be moved to a suitable position first, and then it can be placed on a plane. Before the motor body 1 is installed on the installation surface, in order to improve the supporting strength of the inner side of the motor body 1, a bottom plate 24 is installed on the inner side of the support seat 2, a reinforcing plate 27 and a reinforcing block 28 are installed on the top of the bottom plate 24, and a gasket 34 is embedded inside the reinforcing block 28. Before installing the motor body 1, the gasket 34 is installed in the inner groove 33 inside the reinforcing block 28, and the staff embeds the cross card plate 25 on the side of the reinforcing block 28 in the cross card groove 26 on the inner side of the reinforcing plate 27, so that the two are initially spliced, in which the reinforcing plate 27 is reinforced. The side of the plate 27 is connected with the plug rod 29, and the side of the reinforcing block 28 is provided with a positioning plate 31. The plug rod 29 is inserted into the slot 30, and the positioning plate 31 is embedded in the positioning groove 32. In this way, the support structure can be installed inside the bottom plate 24. The support structure and the support seat 2 structure cooperate with each other. When used, the support seat 2 has a stronger effect. Then the motor body 1 can be installed and fixed on the mounting surface. First, take out the fastener and pass it through the first mounting hole 15 on the top of the mounting seat to fix the position. When it is found that the second mounting hole 17 deviates from the hole position of the mounting surface, a strip groove 16 and a slide groove 19 are opened inside the support seat 2, and the moving block 23 and the threaded column 20 are installed inside the strip groove 16, and the slider is connected to the side of the moving plate. 18. The staff first pulls the slider 18 inside the slide slot 19 to move the threaded column 20 on the side, moves the second mounting hole 17 inside the moving block 23 to a suitable position, and aligns it, then screws the fastener to install it. After the position is fixed, screw the second nut 22 outside the threaded column 20 to fix it. This makes it convenient to adjust the position of the mounting hole in time during installation. In order to improve the heat dissipation performance of the permanent magnet motor, by installing the placement rack 4 and the frame 9 on the outside of the motor body 1, installing the heat sink 10 and the heat sink fins 11 inside the frame 9, and installing the exhaust device 5 and the blowing device 6 on the outside of the placement rack 4, before using the motor body 1, the mounting plate 12 on the side of the placement rack 4 is passed through the threaded rod 13, The first nut 14 on the outside of the threaded rod 13 is screwed to fix the placement rack 4 and the frame 9 to the outside of the motor body 1, and then the staff starts the motor body 1. Since the blowing device 6 is tilted, the blowing device 6 will blow wind to the exhaust device 5. When the exhaust device 5 is started, all the internal heat is discharged, and the wind speed and heat dissipation effect are accelerated during heat dissipation. Secondly, the heat sink 10 and the heat sink fins 11 absorb the heat and discharge it to the outside. In this way, the heat dissipation structure installed on the outside of the placement rack 4 and the frame 9 cooperate with each other, and the heat dissipation performance is better during use. Finally, when the heat dissipation structure occasionally fails, it is only necessary to reversely screw the first nut 14 on the outside of the threaded rod 13 to disassemble and clean it and repair it, and then it can be installed again after maintenance.
