ABSTRACT:
An electric motor having at least two salient stator poles equipped with windings, covering members inserted into gaps between the poles, and a protector switch associated with the field windings. The protector switch is mounted at a predetermined position on one of the covering members using a clamping element which is configured as an elongated component and which is provided with a receptacle for the housing of the protector switch and a holder for leads extending from the switch. The clamping member snaps into a recess in the cover member extending in the direction of the motor axis. The clamping element orients the protector switch so as to avoid contact chatter due to vibration of the motor.
