Motor detection method, electronic equipment, storage medium and computer program product

The invention provides a motor detection method, an electronic device, a storage medium and a computer program product, and the method comprises the steps: determining the reverse electromotive force during the commutation of a motor according to the voltage of a suspended phase when the reverse electromotive force of the suspended phase of the motor crosses a zero point; determining a back electromotive force amplitude according to the back electromotive force; according to the motor out-of-step detection method, the back electromotive force is screened in the real physical quantity, namely, the suspended phase end voltage, compared with a calculation process quantity reconstructed by using a motor dynamic equation, the authenticity and comprehensiveness of a covered motor out-of-step scene are improved, and when the motor is abnormal, the motor is subjected to out-of-step detection. The accuracy and the response timeliness of out-of-step judgment can be obviously improved by the back electromotive force amplitude calculated based on the real physical quantity.
