Problems solved by technology
[0003] However, this kind of compensation is through collecting the current change of the sampling resistor, and indirectly estimating the temperature of the stator winding through the current according to the theory, which has a large deviation from the actual temperature of the stator winding, which will also cause problems in the operation of the motor or poor efficiency under complex working conditions.

The invention provides a method, system and device for adjusting motor operation based on temperature and a storage medium, and belongs to the technical field of motor control, and the method comprises the following steps: a controller controls motor operation; the temperature detection device collects the real-time temperature t of the motor stator winding; the sampling resistor collects a current signal flowing through the motor; calculating the position of the rotor according to the collected real-time temperature t and the current signal of the motor; and the controller adjusts motor operation according to the calculated rotor position. According to the method, the position of the rotor of the motor is calculated by directly collecting the real-time temperature and current during operation of the motor, the operation of the motor is adjusted according to the position of the rotor, and the influence of temperature on electrode operation is solved.
Description
technical field [0001] The invention relates to the technical field of motor control, in particular to a method, system, device and storage medium for adjusting motor operation based on temperature. Background technique [0002] In the actual situation of motor use, the operation of the motor will generate heat, which will cause the resistance and inductance of the motor stator winding to increase, and the increase in resistance will lead to an increase in copper loss. It will cause a phase difference in the detection of the rotor position by the single-chip microcomputer, and there will be a deviation between the output motor operation signal and the actual rotor position, which will eventually lead to a decrease in the performance of the motor, and even cause abnormal operation of the motor. At present, the thermal compensation algorithm is often added to the algorithm, and the compensation is made according to the current change on the sampling resistor and the theoretica...
