Abstract: 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.

Abstract: A stator of an electrical coolant drive includes a stator assembly having a number of stator teeth that are provided with coils of a multi-phase stator winding, and a contact device disposed on the stator assembly on an end side for interconnecting the coils with the phase connections. A deflection region is provided on the outer periphery of the contact device in the region of an inlet of the coolant drive for a fluid flowing in through the inlet. A contact device and an electric coolant drive are also provided.

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: A contact apparatus of a stator has an annular interconnection housing which receives a number of busbars for interconnecting coil ends of a stator winding to a number of phase connections. The interconnection housing has an annularly encircling base section and a number of carrier sections that correspond to the number of phase connections. The carrier sections extend axially starting from the base section, wherein the respective phase connection has an axially extending contact section and a connecting section that runs orthogonally to the axially extending contact section. The respective phase connection is inserted into the associated carrier section in such a way that an axial movement of the contact section of the respective phase connection is blocked in the direction of the base section and is permitted in the opposite direction.
