Torque computation unit for vehicle generator, includes calculator which computes driving torque of generator from field current value, output current value, and rotation speed

摘要

The torque computation unit includes a calculator which computes the driving torque of a generator from the field current value, the output current value, and the rotation speed. The rotation speed is output based on the detected speed of the rotor. The output current value is detected based on the output current of an armature winding.
