摘要:
The apparatus herein provided includes a plurality of systems including driving circuits (20a, 20b) for driving motor coils (3a, 3b) corresponding thereto, and a control unit (10) for controlling control values of the driving circuits (20a, 20b), wherein, when a fault occurs in at least one of the plurality of systems including the motor coils (3a, 3b), the control unit (10) decreases a control value of a system(s) in which the fault occurs from an ordinary time control value or stops the drive by the system(s) in which the fault occurs, and also increases a control value of another system(s) in which the fault does not occur to more than an ordinary time control value.
