摘要： A method for identifying an operational phase of a motor may include obtaining a first value of a signal that is indicative of the operational phase of the motor and obtaining a second value of the signal after a period of time has expired. The method further includes identifying a first operational phase of the motor if the second value exceeds the first value by a non-negative first threshold value. A second operational phase of the motor is identified if the second value does not exceed the first value by the first threshold value. The first and second operational phases may correspond to relative positions of a motor's rotor and stator, such that periods of energization may be identified for producing motoring or regenerative torque.
