    • Disclosed is an electric motor with a sensor, especially for sensing the revolution number. Said sensor contains at least one signal generating unit (20) producing a magnetic field, at least one magnetic-field sensor (28, 30) as a signal detection unit and signal-conductive elements (22, 24, 26). Said signal-conductive elements (22, 23, 26), which contain a magneto-conductive material, routes the signal of the magnetic-field generating element (20) to at least one magnetic-field sensor (28, 30). At least one electro-conductive element (40, 42, 44) is mounted virtually along the signal-conductive element (22, 24, 26).
    • 公开了一种带有传感器的电动机,特别是用于检测转数的电动机。 所述传感器包含产生磁场的至少一个信号产生单元(20),作为信号检测单元的至少一个磁场传感器(28,30)和信号传导元件(22,24,26)。 所述包含磁导材料的信号传导元件(22,23,26)将磁场产生元件(20)的信号路由到至少一个磁场传感器(28,30)。 至少一个导电元件(40,42,44)实际上沿信号传导元件(22,24,26)安装。
