Zusammenfassung:A method and system for detecting a logic level of a rotor of a motor, and a motor are disclosed. The method comprises: obtaining (S11) an analog voltage output by a position sensor for a winding of the motor; setting (S12) a first commutation voltage and a second commutation voltage; generating (S13) a logic level according to the analog voltage, the first commutation voltage and the second commutation voltage; and performing (S14) angle correction on the logic level according to a first angle corresponding to the first commutation voltage and a second angle corresponding to the second commutation voltage. This method may accurately identify the logic level corresponding to the motor rotor, improve uniformity of a commutation voltage and prevent fluctuations in motor speed.
