请参阅图6及图7，所述传感器装置50还包括用于安装所述磁体525的安装件52，所述安装件52一端卡持于所述转轴251并随所述转轴251转动，另一端用于安装所述磁体525。本实施方式中，所述安装件52包括卡持于转轴251的卡持部521和用于容置所述磁体525的容置部524，所述卡持部521一端开设卡持槽522，所述转轴251一端卡持于所述卡持槽522中。具体的，所述转轴251一端开设缺口253，所述卡持槽522的横截面形状与所述转轴251开设缺口253一端的横截面形状相同，以使所述安装件52随所述转轴251转动。
本发明执行器100的控制器30包括密封的壳体31，所述传感器装置50的磁体525安装于所述转轴251一端，所述传感器526安装于所述密封的壳体31中，防止其他物质例如水进入传感器526，造成传感器526失效，另外，所述壳体31的上盖正对所述磁体525的位置开设容置所述传感器526的安装槽323，使得位于所述磁体525和传感器526之间的壳体31的壁厚减小，增强了磁体525与传感器526之间的信号传递，减少阻碍。
本发明的执行器尤其适用于电子离合器***，但并不限定于此应用领域。
由此，本发明令人满意地对实施方式中的技术方案进行清楚、完整地描述，显然，所描述的实施方式仅是本发明一部分实施方式，而没有穷尽性地例举所有可能的实施方式。本领域的技术人员可以对各个实施方式中的技术特征进行各种组合以满足实际需要。基于本发明中的实施方式，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施方式，都属于本发明保护的范围。
