Abstract
An electric motor includes a rotor rotatable about a rotation axis, and a stator that externally surrounds the rotor and includes a stator core and coils wound on the stator core. The windings are defined by a winding wire including winding wire end portions that are electrically contacted at end surfaces thereof by busbars held at least partially in a busbar holder, and include a ground contact to connect the stator to a ground potential. The ground contact includes a first end region received in a longitudinal groove on an outside of the stator core.
