Document Type and Number:
WIPO Patent Application WO/2011/103947
Kind Code:
A3
Abstract:
The invention relates to an electric motor (1) for driving a motor vehicle component, in particular a fan motor for chilling cooling water, comprising a rotor (2) that includes a commutator (3), against which a brush (5) rests in a contacting manner, and a plastic-sheathed pressed screen (10) for forming a current path (9) that is engraved in an electric insulation (24) and is connected to the brush (5). The current path (9) conducting the motor current (IM) is interrupted to form two spaced-apart current path ends (11a, b), the interruption point (12) being bridged by a contact spring (13) that is used as a temperature fuse and consists of two spring legs (13a, b), each of which has a fixing end (14a, b) and a free end (15a, b). Each fixing end (14a, b) of the spring legs (13a, b) is connected to a current path end (11a, b), while the free ends (15a, b) thereof are in contact with each other using a soldered connection (16) so as to bias the spring.
