Description
Technical Field
[0001] The present invention relates to the technical field related to permanent magnet motors, and in particular to an adaptive load permanent magnet motor control device. Background Art
[0002] A permanent magnet 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 permanent magnet synchronous motor is composed of a stator, a rotor, an end cover and other components. The stator is basically the same as an ordinary induction motor. A laminated structure is used to reduce the iron loss of the motor during operation. The rotor can be made solid or laminated. The armature winding can be a concentrated full-pitch winding, or a distributed short-pitch winding and an unconventional 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 a greater output torque. The motor control system will accurately adjust the current to ensure that the motor rotor can rotate synchronously with the rotating magnetic field and maintain a stable operating state. Permanent magnet motors are generally installed on control devices, and they need to be adaptive to the load, thereby requiring an adaptive load permanent magnet motor control device.
[0003] At present, when relevant technical personnel need to use the adaptive load permanent magnet motor control device during the adaptive load process of the permanent magnet motor, the equipment is overloaded due to long use time and the equipment needs to be adjusted. After the adjustment, the permanent magnet motor needs to be reloaded, which wastes a lot of time. In addition, the permanent magnet motor will jitter during the loading process and its fixity cannot be guaranteed, thereby reducing the load efficiency. Summary of the invention

The load-bearing block 22, the first limiting column 23, the first spring 24, the second limiting column 25, the base plate 26, the buffer 27, the fixing rod 28 and the second spring 29 are arranged. When in use, when the permanent magnet motor needs to be loaded, the permanent magnet motor is first placed on the load plate 21, and the load plate 21 will be subjected to pressure. At this time, the force will be applied to the load-bearing block 22 together, the first limiting column 23 will squeeze downward, and then the force will be transmitted to the base plate 26 through the first spring 24 for unloading, and the second limiting column 25 will limit the first spring 24, and part of the force will be transmitted to the fixing rod 28 through the buffer 27, so that the second spring 29 is deformed and then rebounds to disperse the force to both sides, thereby dispersing the force and loading the permanent magnet motor.
[0024] Furthermore, the clamping mechanism 3 includes an output member 31, a fixing plate 32, a fixing column 33, a connecting column 34, a third spring 35 and a clamping plate 36. The output member 31 is installed on the inner wall of the control device housing 1. The output end of the output member 31 is fixed with the fixing plate 32. The outer wall of the fixing plate 32 is fixed with the fixing column 33. The inner wall of the fixing column 33 is slidably connected with the connecting column 34. The third spring 35 is installed on the outside of the connecting column 34. The clamping plate 36 is fixed at one end of the connecting column 34. The arrangement of the column 33, the connecting column 34, the third spring 35 and the clamping plate 36, when in use, when clamping the permanent magnet motor, the output member 31 begins to adjust the clamping force, and at the same time the output member 31 applies a thrust to the fixed plate 32, at this time, the fixed column 33 and the connecting column 34 on one side of the fixed plate 32 are extended and retracted by the thrust, the third spring 35 on the outside buffers the fixed column 33 and the connecting column 34, and then the third spring 35 applies a thrust to the clamping plate 36, thereby clamping the permanent magnet motor, wherein the output member 31 is a cylinder.
[0025] Furthermore, the load-bearing block 22 is symmetrically arranged with respect to the central axis of the long side of the upper surface of the control device housing 1, and the first limit columns 23 are evenly spaced and distributed at the bottom of the load plate 21. By setting the load-bearing block 22, the permanent magnet motor can be placed on the load plate 21, and the load plate 21 will be subjected to pressure, and at this time, the force will be applied to the load-bearing block 22 together.
[0026] Furthermore, the first springs 24 are distributed at equal intervals on the outer wall of the first limiting column 23, and the second limiting columns 25 are distributed at equal intervals on the upper surface of the bottom plate 26. Through the setting of the first spring 24, the first limiting column 23 can be squeezed downward, and then the force will be transmitted to the bottom plate 26 through the first spring 24 to unload the force, while the second limiting column 25 limits the first spring 24.
[0027] Furthermore, the buffers 27 are distributed at equal intervals on the outer wall of the load-bearing block 22, and the second springs 29 are symmetrically arranged with the central axis of the long side of the upper surface of the control device housing 1. Through the arrangement of the buffers 27, a part of the force will be transmitted to the fixing rod 28 through the buffers 27, causing the second springs 29 to deform and then rebound to disperse the force to both sides, thereby dissipating the force.
[0028] Furthermore, the output members 31 are evenly spaced on the inner wall of the control device housing 1, and the inner wall size of the fixing column 33 matches the outer wall size of the connecting column 34. By setting the output member 31, the output member 31 can apply a thrust to the fixing plate 32. At this time, the fixing column 33 and the connecting column 34 on one side of the fixing plate 32 are extended and retracted by the thrust.
[0029] Furthermore, the third springs 35 are distributed at equal intervals outside the connecting column 34, and the clamping plates 36 are distributed at equal intervals at one end of the connecting column 34. Through the setting of the third springs 35, the outer third springs 35 can buffer the fixing column 33 and the connecting column 34, and then the third springs 35 apply thrust to the clamping plates 36.
[0030] Working principle: First, when the permanent magnet motor needs to be loaded, the permanent magnet motor is first placed on the load plate 21, and the load plate 21 will be subjected to pressure. At this time, the force will be applied to the load-bearing block 22 together, and the first limit column 23 will squeeze downward, and then the force will be transmitted to the bottom plate 26 through the first spring 24 to unload the force, and the second limit column 25 will limit the first spring 24, and part of the force will be transmitted to the fixing rod 28 through the buffer 27, so that the second spring 29 will deform and then rebound to make the force Dispersed to both sides, so as to disperse the force, thereby loading the permanent magnet motor. When clamping the permanent magnet motor, the output member 31 begins to adjust the clamping force, and at the same time, the output member 31 applies a thrust to the fixed plate 32. At this time, the fixed column 33 and the connecting column 34 on one side of the fixed plate 32 are extended and retracted by the thrust, and the third spring 35 on the outside buffers the fixed column 33 and the connecting column 34. Then the third spring 35 applies a thrust to the clamping plate 36, thereby clamping the permanent magnet motor, wherein the output member 31 is a cylinder.
