STATOR WITH TERMINAL CONNECTOR Russian patent published in 2022 - IPC H02K3/52 B60K7/00 H02K7/00 H02K1/12 

FIELD: electrical engineering.

SUBSTANCE: motor built in a wheel contains a stator and a rotor placed around the stator. The stator contains a cylindrical surface and coils with windings around core elements oriented in the axial direction, and it contains coil terminals. The motor additionally contains a connector containing at least two mutually isolated conductors placed at the first end of the cylindrical surface near curved winding ends. Each conductor contains a ring-shaped conductive main part and a set of contact elements extended from the mentioned conductive main part and placed for connection to one of the mentioned terminals. At the same time, ring-shaped conductive main parts are located at a distance from each other in the axial direction. The connector contains a ring-shaped main part of an insulator with at least two grooves located at a distance in the axial direction, each of which holds corresponding one of the mentioned conductors. Each contact element contains the first and the second parts and a curved fragment on its side facing axial core elements. The second parts of contact elements are located next to each other in a circumferential direction of the main part of the insulator. The terminal creates a sliding contact with the curved fragment and the second part of the contact element.

EFFECT: simplification of connection of a connector to coil terminals.
