Abstract
An electric motor of a vehicle component, in particular a window opener drive or seat adjuster drive, includes a rotor, a stator with a three-phase stator winding having at least one coil per phase with first and second coil ends, and a connection element having a number of vias corresponding to the number of coil ends, the vias forming first and second contacting groups. The vias of the first contacting group are paired with a contact ring with contact points for electrically conductively connecting the first coil ends, in particular while forming a neutral point. The second coil ends are guided through the vias of the second contacting group, and a coil end portion or additional conductor element of the coil ends is azimuthally guided along the connection element and guided, preferably axially, out of the connection element while providing a three-phase winding connection at exposed positions.
