ABSTRACT:
A motor controller is provided which improves response to control inversion of a motor, and which also improves controllability and driving comfort when applied to electric power steering. In the motor controller a bridge circuit 5 is formed which includes switching elements 3a to 3d which are driven to control the motor 2 in a direction of conduction, a drive system is switched between a single-phase one-sided chopper system and either a single-phase double-sided chopper system or a double-phase double-sided chopper system based on detected states of an apparatus or the amount of control, so as to control the motor 2 with a drive system suitable for each state of the apparatus.
