    • An electric motor has a switching device, a driving circuit connectable to a voltage supply through the switching device and having a drive shaft, a mechanically acting braking device for braking the drive shaft when disconnecting the electric motor from the voltage supply, a rotor serving to generate torque and acted upon by a mechanical braking force when switching off the voltage supply, at least one radially displaceable part which applies the braking force and is magnetizable and acted upon by an electromagnetic releasing force which is directed opposite to the braking force and is greater than the braking force, and a stator having an axial slit which is overlapped by the part, and at least one shorted turn arranged in an area of the slit.
    • 电动机具有开关装置,通过开关装置与电压源连接的驱动电路,具有驱动轴,用于在将电动马达与电源断开时制动驱动轴的机械动作制动装置, 产生转矩并在关闭电源时由机械制动力作用,至少一个可施加制动力的可径向移动的部件可磁化并通过与制动力相反的电磁释放力作用,并且更大 以及具有与所述部分重叠的轴向狭缝的定子和设置在所述狭缝的区域中的至少一个短路匝。
