<P>PROBLEM TO BE SOLVED: To accurately and readily estimate a current which flows to a motor. <P>SOLUTION: The motor controller includes a PWM voltage control unit which drives a motor in PWM control; a current control unit which controls a current to be supplied to the motor; and an estimator which estimates the current flowing to the motor by using a parameter related to the motor, based on the duty of the PWM control requested in the PWM voltage control, and the parameter is computed by controlling the motor with the current control unit. <P>COPYRIGHT: (C)2011,JPO&INPIT |
