Beschreibung
Zusammenfassung:	Disclosed herein is a motor driver including: a motor current phase detector configured to detect a motor current phase and output a result of the detection as motor current phase information; a motor phase detector configured to detect a motor phase and output a result of the detection as motor phase information; a phase correction value calculator configured to calculate a correction value based on a difference between the motor current phase information and the motor phase information and output a result of the calculation as compensation information; and a motor applied voltage calculator configured to calculate a motor applied voltage representing a voltage to be applied to the motor based on the compensation information and motor phase information received and output a result of the calculation as a phase-compensated motor applied voltage signal.
