摘要： A motor control device has a motor driving unit that drives a motor, a current detecting unit that detects a motor current flowing through the motor, a control unit that compares a detected current value of the motor current detected by the current detecting unit with a target current value to obtain a deviation, to control the motor driving unit based on the deviation, and a compensation unit that sets as a current offset value a detected current value of a drift current detected by the current detecting unit in a state where the motor current is regarded as zero, to compensate the detected current value of the motor current by the current offset value. The compensation unit sets a target offset value according to the current value of the detected drift current to correct the current offset value stepwise until the current offset value reaches the target offset value.
