Title:
ELECTRIC MOTOR AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/272945
Kind Code:
A1
Abstract:
Provided in the present application are an electric motor and a vehicle. The electric motor comprises a metal member, a rotor core, a rotating shaft, a conductive bearing and an elastic conductive member, wherein the metal member is grounded, the rotor core is arranged on one side of the metal member, and the rotor core comprises a shaft hole. The rotating shaft is connected to the rotor core, and the rotating shaft is arranged in the shaft hole in a penetrating manner. The conductive bearing is sleeved on the rotating shaft. At least part of the elastic conductive member is arranged between the conductive bearing and the metal member. In the present application, the elastic conductive member generates a pressing force by means of its own elastic deformation, so as to be in close contact with the conductive bearing, such that the contact resistance between the elastic conductive member and the conductive bearing may be reduced, a guiding effect on a shaft current is achieved, and thus the shaft current is prevented from corroding a slewing bearing of the electric motor, thereby prolonging the service life of the conductive bearing and the slewing bearing.
