Abstract
An electric motor for driving a motor vehicle component, in particular a fan impeller for cooling cooling water, having an electronics unit that includes a lead frame around which injection-molded plastic is provided and which has a current path conducting the motor current, and having two spaced-apart current path ends that form an interruption point bridged by a thermal fuse in the form of a spring-biased contact bridge. The contact bridge is mounted so as to be pivotable about an axis of rotation extending perpendicular to the plane of the interruption point. An abutment contour, against which the contact bridge pivots as a result of the restoring force of a spring element when the thermal fuse is triggered, limits the pivoting range of the contact bridge.
