Title:
STATOR WINDING CONNECTOR, STATOR WINDING AND ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2024/001020
Kind Code:
A1
Abstract:
Provided in the present invention are a stator winding connector, a stator winding and an electric motor. The stator winding connector is configured to be arranged on a conductor of a winding and comprises a connector body, wherein the connector body is provided with a connection surface and a first avoidance surface, and the first avoidance surface is located on an opposite side of the connection surface. The first avoidance surface is configured in such a way that: after a first conductor and a second conductor in the same conductor group are mounted in a stator slot of a stator and positioned relatively, the connector body on any one conductor does not exceed an insulation layer of the other conductor. By arranging the first avoidance surface on the opposite side of the connection surface, an avoidance relationship between adjacent conductor groups is formed, thereby increasing an electrical gap between the adjacent conductor groups and making a winding structure satisfy creepage distance requirements of an electric motor. Moreover, due to avoidance of the first avoidance surface regarding the insulation layer of an adjacent conductor, the connector is not in contact with the insulation layer of the adjacent conductor when the connector is bent and twisted at the connector, such that damage to the insulation layer can be avoided.
