The invention belongs to the technical field of vehicles, and discloses a motor system control method and device, equipment and a storage medium. The method is applied to a motor system and comprises the steps that the current electronic water pump rotating speed and electronic water pump operation data are obtained; determining a difference electronic water pump rotating speed according to the current electronic water pump rotating speed and a preset electronic water pump rotating speed; when the difference value electronic water pump rotating speed is larger than a difference value electronic rotating speed threshold value, target output torque is determined according to the electronic water pump operation data; and controlling the motor to perform torque output according to the target output torque. The target output torque is determined through the difference value electronic water pump rotating speed and the difference value electronic rotating speed threshold value so as to control the motor to carry out torque output, and it is guaranteed that diagnosis and fault-tolerant processing are carried out on cooling system faults of the motor and a motor controller under different conditions through software and hardware design. And the reliability and the safety of the thermal management function of the motor and the motor controller are improved.
