Abstract

A current supply system configured to receive a rotational driving force and supply a current for driving an electrical load device in accordance with a current requirement. The current supply system includes a rotor, including a permanent magnet, configured to receive the rotational driving force, and a stator including a stator core with a winding wound thereon, a magnetic circuit for the winding passing through the stator core, the rotational driving force causing the rotor and the stator to generate the current. The current supply system further includes a supply current adjustment device configured to change magnetic resistance of the magnetic circuit for the winding in accordance with the current requirement, to thereby change an inductance of the winding to adjust the generated current.
