Abstract

See full text

A stator contains a stator assembly having a number of stator teeth, which are provided with coils of a multi-phase stator winding, and a contact device for interconnecting axially orientated coil ends of the coils with a number of phase connections. The contact device has an interconnection ring fitted on the stator assembly on the end side and has integrated bus bars for interconnecting the coils with the phase connections. The contact device has a ring cover fitted on the interconnection ring. The interconnection ring has a number of axial through-openings corresponding to the number of coils ends, through which the coils ends are guided. The bus bars have contact tabs at the ends of the bar, which are arranged in a region of the through-openings, and on which a respective coil end is contacted. The ring cover covers the coil ends and contact tabs.
