Technical Field
[0001] The present invention relates to the technical field of motors, and in particular to an intelligent motor design method, a motor and a deviation correction method thereof. Background Art
[0002] Motors include electric motors and generators. They are devices that realize the mutual conversion between electrical energy and mechanical energy. They have been widely used in various industries. When the motor moves at high speed, its mechanical part may rotate or tilt, causing the motor to not be in the normal working point. If there is no correction method, the working performance of the motor will be reduced. In severe cases, it will cause abnormal noise from the motor or even damage the motor. Summary of the invention
[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and propose a new high-performance intelligent motor design method, a motor and its correction method. An adaptive tension spring structure is designed in the rotor assembly to avoid the interference of the motor position or other external forces on the motor movement. The rotor automatically seeks balance according to the centripetal force during high-speed rotation, thereby ensuring the high-speed operation performance of the motor and reducing losses, ensuring that the motor can run in an ultra-high-speed state for a long time. At the same time, an aerodynamic design suitable for the ultra-high-speed operation state of the motor is designed at the casing to put the motor air in a diversion operation state.
[0004] The object of the present invention is achieved by the following technical solution: a method for designing an intelligent motor, wherein the motor comprises a stator assembly, a rotor assembly, a housing and a control board, and the method comprises:
[0005] Design the stator assembly, using N groups of stator core components to be wound in series without spacing and assembled into a closed structure;
[0006] Design the rotor assembly, use springs to be set at both ends of the magnetic core of the rotor assembly, and use the springs to support the bidirectional movement of the magnetic core, forming an adaptive tension spring structure. The adaptive tension spring structure allows the rotor assembly to automatically find balance according to the centripetal force during ultra-high-speed rotation;
[0007] The casing is designed with an arc-shaped guide vane, a guide groove and a high-speed fan guide vane that matches the motor integrally formed inside the casing, forming a rotating air duct structure suitable for the ultra-high-speed operation of the motor. The air entering the motor is discharged through the rotating air duct structure, so that the discharged air forms a rotating airflow, and the air outlet speed is higher, and the air outlet position can be customized; and a symmetrical hollow position is formed at the end of the casing, so that the motor rotating air duct takes away heat through the hollow position, thereby improving the working power and speed of the motor. At the same time, a bearing is provided in the casing, so that the whole casing is constituted as an adaptive magnetic field balance body with a bearing;
[0008] A control board is designed, which drives the motor to run and integrates an active voice noise reduction calculation model. It can automatically switch between different noise reduction modes according to the environment to achieve noise reduction output.
[0009] Furthermore, each set of stator core components includes a stator module, a winding slot sleeved on the stator module, an outer coil wound on the winding slot, a wiring bracket and a PIN pin installed on the wiring bracket, forming a through stator slot without spacing in the closed structure.
[0010] Furthermore, the adaptive tension spring structure includes a motor shaft, a magnetic core and a spring. The magnetic core is mounted on the motor shaft. The spring is mounted on the motor shaft and located at both ends of the magnetic core to support the movement of the magnetic core front and back.
[0011] Furthermore, the rotating air duct structure is integrally formed in the casing, so that the rotating air duct structure as a whole is firmly fixed, wherein smooth arc-shaped guide vanes are used, and the direction of the arc-shaped guide vanes is consistent with the direction of the air entering the motor, so that the whole is in a diversion operation state, thereby allowing wind to smoothly enter and exit the motor, reducing internal losses, and is suitable for high-speed rotation of the motor.
[0012] Furthermore, the symmetrical hollow positions at the end of the housing are connected to the tail plate of the motor through PIN pins to supply power.
[0013] Furthermore, the active speech noise reduction calculation model adjusts ANC controller parameters according to wind noise detection results, optimizes wind noise leakage, and achieves a rapid reduction in erroneous signals input to the filter, thereby reducing noise.
[0014] A motor comprises a stator assembly, a rotor assembly, a casing and a control board, wherein the stator assembly, the rotor assembly, the casing and the control board are designed according to the above-mentioned intelligent motor design method.
[0015] A method for correcting the deviation of a motor. The method uses an adaptive tension spring structure designed based on the above-mentioned intelligent motor design method to correct the deviation of the motor. When the motor rotates at ultra-high speed and causes tilt, the motor on the side close to the motor shaft squeezes the spring so that the spring provides a reverse elastic force to one side of the motor, and the magnitude of the force is positively correlated with the squeezing distance received; at the same time, the motor on the side far from the motor shaft stretches the spring so that the spring provides a reverse pulling force to one side of the motor, and the magnitude of the force is positively correlated with the stretching distance received, thereby forming a vibration response, and the vibration amplitude becomes smaller and smaller, and finally tends to 0, that is, the deviation is corrected to a normal value.
[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0017] 1. When a traditional motor moves at high speed, its mechanical part may rotate or tilt, causing the motor to not be at the normal working point. The present invention can realize intelligent deviation correction of the motor, so that the rotor assembly can automatically find balance according to the centripetal force during high-speed rotation, thereby ensuring the high-speed operation performance of the motor, reducing losses, and ensuring that the motor can run at ultra-high speed for a long time;
[0018] 2. The present invention can form a specific rotating airflow when the air flows through the inside of the motor, so that the air outlet speed is higher; a symmetrical hollow position is formed at the end of the casing, so that the rotating air duct of the motor can take away heat through the hollow position, thereby improving the working power and speed of the motor.
