    • Electromagnetic actuators (100, 200), components of electromagnetic actuators, clutches that use electromagnetic actuators, and methods associated therewith for improved electromagnetic actuator operation and manufacturing methods. Embodiments of an electromagnetic actuator of the present disclosure includes a configuration of a housing (112, 212) and a flux washer (106, 206) relative a shaft (108, 208) helps to reduce the travel path for magnetic flux generated by an electrical coil (102, 202) contained therein. This more direct flux path, in turn, provides for a shorter loop for the magnetic flux, which helps to generate a greater relative magnetic force (e.g., a stronger clutch actuation force) as compared to other configurations.
    • 电磁致动器(100,200),电磁致动器的部件,使用电磁致动器的离合器,以及与之相关的方法,用于改进的电磁致动器操作和制造方法。 本公开的电磁致动器的实施例包括相对于轴(108,208)的壳体(112,212)和助焊剂垫圈(106,206)的构造,有助于减小由电气产生的磁通量的行进路径 线圈(102,202)。 反过来,这种更直接的通量路径为磁通量提供了更短的回路,与其他构造相比,这有助于产生更大的相对磁力(例如,较强的离合器致动力)。
