To provide an electromagnetic actuator capable of improving responsiveness of a connecting/disconnecting part.SOLUTION: An electromagnetic actuator 1 includes: a pair of rotary members 3, 5 which can rotate relatively; a connecting/disconnecting part 7 for connecting/disconnecting power transmission between the pair of rotary members 3, 5; an electromagnet 9 for actuating the connecting/disconnecting part 7; and control means 11 for controlling electric conduction to the electromagnet 9. The control means 11 imparts an additional current I1 to the electromagnet 9 in which a response coefficient K0 determined by request torque a, and at least one of differential rotation c of the pair of rotary members and temperature b of the connecting/disconnecting part 7 is taken into consideration of a current value I0 determined according to the request torque a which is added to the connecting/disconnecting part 7.SELECTED DRAWING: Figure 1

    【課題】断続部の応答性を向上することができる電磁式アクチュエータを提供する。【解決手段】相対回転可能な一対の回転部材3,5と、この一対の回転部材3,5との間の動力伝達を断続する断続部7と、この断続部7を作動させる電磁石9と、この電磁石9への通電を制御する制御手段11とを備えた電磁式アクチュエータ1において、制御手段11が、断続部7に付与されるリクエストトルクaに応じて決定された電流値I0に、リクエストトルクaと、一対の回転部材の差回転cと断続部7の温度bとのうち少なくともいずれか一方とから決定される応答係数K0を考慮した付加電流I1を電磁石9に与えた。【選択図】図1
