The invention relates to an electromagnetic actuator (105) comprising a coil element (110) having at least one coil core (135) and a coil (140) arranged circumferentially around the coil core (135), and a movable armature body (115) as a movable actuator element, the coil core (135) having a rotationally symmetrical first region (136) having an axis of symmetry (137), the axis of symmetry (137) being substantially parallel to the axis of symmetry (137), the axis of symmetry (137) being substantially parallel to the axis of symmetry (137), and the axis of symmetry (137) being substantially parallel to the axis of symmetry (137). The coil element (110) has a first region in which the coil core (135) is surrounded circumferentially by the coil (140), and an armature body (115) which interacts with the coil element (110) for a movement to be activated of the armature body (115), the armature body is mounted on one side in the actuator (105) by means of a bearing device (106) and can be moved from a first position (147) into a second position (149) by activating the coil element (110), the bearing device (106) being arranged radially offset with respect to an axis of symmetry (137) of the coil core (135), the armature body (115) extends from the bearing device (106) radially on the coil core (135) from a first side (131) to a second side (132) of the coil core (135). The coil core (135) has a second region (138), which extends radially beyond the first region (136) and is arranged between the coil (140) and the armature body (115) on a second side (132) of the coil core (135) in the direction of the axis of symmetry (137), such that in a first position (147) of the armature body (115), the second region (138) extends radially beyond the first region (136). An air gap (190) between the coil core (135) and the armature body (115) in the direction of the axis of symmetry (137) is smaller on a second side (132) of the coil core (135) than on the first side (131).

    电磁促动器(105)包括线圈元件(110)和作为能够运动的促动器元件的能够运动的磁衔铁体(115),所述线圈元件具有至少一个线圈芯(135)以及周向地围绕所述线圈芯(135)布置的线圈(140),其中,所述线圈芯(135)具有旋转对称的第一区域(136),所述第一区域具有对称轴线(137),在所述第一区域中,所述线圈芯(135)周向地被所述线圈(140)包围,所述衔铁体与所述线圈元件(110)共同作用,用于所述衔铁体(115)的待激活的运动,所述衔铁体在一侧借助支承设备(106)支承在所述促动器(105)中并且通过激活所述线圈元件(110)能够从第一位置(147)运动到第二位置(149)中,其中,所述支承设备(106)在径向上相对于所述线圈芯(135)的对称轴线(137)错位地布置,并且所述衔铁体(115)从所述支承设备(106)在径向上在所述线圈芯(135)上从所述线圈芯(135)的第一侧(131)延伸至第二侧(132)。所述线圈芯(135)具有第二区域(138),所述第二区域在径向上延伸超过所述第一区域(136)并且在所述线圈芯(135)的第二侧(132)上在所述对称轴线(137)的方向上布置在所述线圈(140)与所述衔铁体(115)之间,使得在所述衔铁体(115)的第一位置(147)中,在所述对称轴线(137)的方向上在线圈芯(135)与衔铁体(115)之间的气隙(190)在所述线圈芯(135)的第二侧(132)上比在所述第一侧(131)上小。
