To provide an electromagnetic actuator capable of accurately controlling a connection/disconnection state 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 determines an additional current I1 selected from among request torque a, differential rotation c of the pair of rotary members 3, 5 and temperature b of the connecting/disconnecting part 7, and adds it to the electromagnet 9.SELECTED DRAWING: Figure 1

    【課題】断続部の断続状態を的確に制御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、リクエストトルクaと、一対の回転部材3,5の差回転cと、断続部7の温度bとから選択される付加電流I1を決定し、電磁石9に付与した。【選択図】図1
