PROBLEM TO BE SOLVED: To provide a motor controller which can minimize decrease in revolving speed of a motor immediately after switching from forced drive control to feedback control, while reducing the risk of disabling rotor position detection. ! SOLUTION: When obtaining a current command by feedback control immediately after switching from forced drive control to feedback control, initial value of integration value in an integration path is set to a predetermined value larger than 0. Immediately after switching from forced drive control to feedback control, decrease of a current command given to PWM drive means is suppressed thus suppressing drop in the duty ratio. !
