Abstract
A control system for motor configured to control currents supplied to an armature coil and a field coil properly to achieve a required torque. The control system controls torque of a rotor by controlling a base torque generated by energizing an armature coil, and a field torque generated by energizing a field coil. When a target torque is equal to or greater than a predetermined torque, the controller controls the base torque and the field torque such that a ratio of the field torque to the target torque is increased greater than that of a case in which the target torque is less than the predetermined torque.
