Internal combustion driven automotive alternator having inertial torque change control circuit

摘要

A controller for an alternator driven by an output torque of an automotive engine mechanically through a belt is provided. The controller works to control an exciting current supplied to a field winding of the alternator so as to cancel a change in inertia torque of a rotor of the alternator arising from a change in speed of the engine, thereby minimizing a change in tension of the belt.
