Bell-armature electric motor has openings in collector disc provided with chip capacitors connected between short-circuit ring and terminal tags for collector lamella elements

摘要

The electric motor has a collector provided with a number of collector lamella elements (7) forming a collector sleeve (8) and a collector disc (4) for securing a winding sleeve. The collector disc has a number of openings (13) parallel to the motor axis, each associated with a terminal tag (11) of a collector lamella element which is connected to a winding coil of the winding sleeve. A chip capacitor (16) is located in each opening, coupled to the terminal tag and a short-circuit ring (19) on the opposite side of the collector disc via its opposing terminals. Also included are Independent claims for the following: (a) an attachment for an electric motor; (b) an electric motor manufacturing method
