The invention discloses a permanent magnet synchronous motor control method, device and equipment and a storage medium, and relates to the technical field of vehicle control, and the permanent magnet synchronous motor control method comprises the steps: determining a voltage derating feedforward value according to a preset reference voltage value and a current back electromotive force feedforward value; determining a target efficiency reduction voltage value according to the voltage derating feedforward value and the output voltage derating value; determining a target output current according to the target efficiency reduction voltage value, the preset reference voltage value and a preset active field weakening control strategy; and controlling the permanent magnet synchronous motor according to the target output current. Active flux weakening and efficiency-reducing heating are integrated together, and the reference voltage of the active flux weakening is automatically adjusted through the target heating power, so that the target current is automatically adjusted, the effect of active heating is achieved, and the torque precision of the pure electric vehicle in the efficiency-reducing heating state is improved.
