Abstract: A stator of an electric motor includes a stator main body which supports coils each having two coil ends of a multiphase stator winding. A contact apparatus is disposed on the end face of the stator main body and has an interconnection housing that receives a number of busbars for interconnecting the coils and a number of phase connections. Each phase of the stator winding is formed by at least one of the coils and at least one of the busbars as well as one of the phase connections. The dimensions of the busbars are set in such a way that the electrical resistance of all of the phases of the stator winding is the same. An electric motor having the stator is also provided.

Abstract: An electric machine of a motor vehicle, in particular of an adjustment drive or of a radiator fan, has a rotor which is mounted so as to be rotatable about a machine axis. The rotor has a number of permanent magnets which are arranged in the radial direction. Each permanent magnet has one side with a strong magnetic flux and one side with a weak magnetic flux in the tangential direction. When the permanent magnets are adjacent in the tangential direction, different sides are directed towards one another.
