The invention provides an electromagnetic actuator device capable of reducing pulsation and improving thrust. This electromagnetic actuator device is provided with a magnet part (20) and an armature (10) that moves relative to the magnet part (20). The armature (10) includes a plurality of teeth (12) formed in a relative movement direction; a plurality of grooves (15) formed between the plurality of teeth (12); a yoke (14) connecting the plurality of teeth (12); and a winding (13) wound around the plurality of slots (15). The magnet part (20) comprises a plurality of magnets (21) which face the plurality of teeth (12) with gaps therebetween and are arranged in the relative movement direction. The relationship between the minimum cross-sectional area Sc1 of one tooth end portion (12c) of the armature (10) and the minimum cross-sectional area Sc2 of the other tooth end portion (12b) is Sc1 > Sc2, and the relationship between the minimum cross-sectional area Sc2 of the other tooth end portion (12b) and the cross-sectional area Sy of the yoke (14) in a direction crossing the relative movement direction is Sc2 > = Sy.

    本发明提供一种能够减少脉动并提高推力的电磁致动器装置。本发明的电磁致动器装置包括磁体部(20)和与磁体部(20)相对移动的电枢(10)。电枢(10)包括沿相对移动方向形成的多个齿(12);形成在多个齿(12)之间的多个槽(15);连接多个齿(12)的磁轭(14);以及卷绕在多个槽(15)上的绕组(13)。磁体部(20)包括隔着空隙与多个齿(12)相对并且沿相对移动方向配置的多个磁体(21)。电枢(10)的一个齿端部(12c)的最小截面积Sc1与另一个齿端部(12b)的最小截面积Sc2的关系为Sc1>Sc2,且另一个齿端部(12b)的最小截面积Sc2与横穿过相对运动方向的方向上的磁轭(14)的截面积Sy的关系为Sc2≥Sy。
