  • Publication number: 20240072596
    Abstract: A stator for an electrical refrigerant drive includes a laminated core wound with a stator winding, and a contact adapter mounted on the laminated core for connecting the stator winding to at least one phase connector. The contact adapter has at least one potting pocket and the phase connector is fitted in the potting pocket. A winding portion of the stator winding is guided into the potting pocket and contacted with the phase connector. The potting pocket is filled with a cured potting material. A motor vehicle electrical refrigerant drive having the stator is also provided.

  • Publication number: 20220190668
    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.

  • Patent number: 10547227
    Abstract: An electromagnetic structure of an electric machine, in particular an adjustment drive of a motor vehicle, has a plurality of coils which are arranged to form a circular structure. Each of the coils has a coil winding and a connection. The coils are respectively electrically connected in pairs by way of a conductor bridge which is in contact with the respective connections. Each conductor bridge is arranged at an axial distance from the associated coils, each conductor bridge being arranged at least partially in a receiving element of a guiding plate.

  • Patent number: 9787155
    Abstract: A stator system for an electric motor has multiple coil formers and stator windings that are wound on the coil formers. The stator windings are distributed over the circumference of the stator system and are arranged to form a substantially circular stator star. A number of the stator windings are electrically insulated in the axial direction in each case by way of a phase separator. The stator windings in each case of two coil formers are electrically connected as a coil pair in an electrically conductive manner by a conductor track. The conductor track is retained by a separating web that is arranged in the axial direction above the allocated phase separator and that extends in a radial direction.
