PROBLEM TO BE SOLVED: To provide a compact current supply system applicable to both a drive source of wide rotational speed range and a drive source of narrow rotational speed range, and capable of supplying a current suitably.SOLUTION: A current supply system for receiving a rotational driving force from a drive source, and supplying a current to an electric load device, current demand of which changes, includes a rotor having a permanent magnet and connected with the drive source, a stator having a winding and a stator core around which the winding is wound and placed oppositely to the rotor, and a supply current adjustment section for adjusting the current supplied to the electric load device, by changing the magnetic resistance of the stator core, viewing from the winding, in response to a current demand for the current supply system, thereby changing the inductance of the winding.SELECTED DRAWING: Figure 1

    【課題】小型化でき、且つ回転速度の範囲が広い駆動源及び回転速度の範囲が狭い駆動源の双方に適用可能であり、電流の供給を好適に行うことができる電流供給システム等を提供する。【解決手段】駆動源から回転駆動力を受けるとともに、電流の要求が変化する電気負荷装置に電流を供給する電流供給システムであって、前記電流供給システムは、永久磁石を有し前記駆動源に接続されたロータと、巻線及び前記巻線が巻かれたステータコアを有し前記ロータと対向して配置されたステータと、前記電流供給システムに要求される電流要求に応じて前記巻線から見た前記ステータコアの磁気抵抗を変えることによって前記巻線のインダクタンスを変え、前記電気負荷装置に供給する電流を調整する供給電流調整部とを備える。【選択図】 図1
