摘要： A power tool is provided including a housing and an electric motor including a stator and an armature rotatably received within the stator. The armature includes an armature shaft on which a commutator is mounted. The power tool includes a rear bearing mounted on the armature shaft adjacent the armature, and a brush assembly disposed around the commutator. The brush assembly includes a brush card, at least two brushes secured to the brush card around and in contact with the commutator, and a bridge cap extending from the brush card via legs and forming a bearing support for supporting the rearing bearing. At least one electromagnetic interference (EMI) suppression component is provided having a first terminal electrically coupled to the brush(es) and a second terminal electrically coupled to the rear bearing through the bridge cap so as to substantially ground the second terminal of the EMI suppression component.

摘要： An electric motor for driving a motor vehicle component, such as a fan motor for cooling cooling water, has a thermal fuse with a contact spring. The contact spring has attached ends that are connected to a conducting path section between which an interruption point is formed. The springy ends of the contact spring are in soldered contact with each other in a spring-biased manner. The thermal fuse is a fuse module with a plastic support in which the conducting path sections are partially embedded in such a way that the contact spring lies in a window opening in the support. Terminals of the conducting path sections protrude from the plastic support.
