Motor thermal protection control method, device and equipment and storage medium

The invention belongs to the technical field of vehicles, and discloses a motor thermal protection control method, device and equipment and a storage medium. The method is applied to the motor system, the motor system comprises a motor controller, a motor and a motor water outlet temperature sensor, and the motor controller comprises a temperature sensor. Determining an initial motor temperature according to the current water outlet temperature and the motor temperature increment; when the controller temperature is within a preset controller temperature range, determining a target motor output torque according to the initial motor temperature; and controlling the motor according to the target motor output torque. Through the method, the motor system can work reliably and safely in various application scenes and working conditions, the system diagnosis requirement of the motor system under the motor over-temperature fault is met, the material cost of the motor is reduced, and the reliability of the motor therm
