  • Motor, powertrain, and vehicle
    Patent number: 12113421
    Abstract: This application describes a motor that includes a housing, an output shaft, a conductive bearing, and a conductive component. The output shaft is disposed in the housing. A positioning hole is disposed on an end face of a first end of the output shaft, and the positioning hole is disposed coaxially with the output shaft. The conductive bearing is disposed in the positioning hole, and includes an inner ring, and an outer ring that is fixedly connected to the output shaft. One end of the conductive component is fixedly connected to the inner ring of the conductive bearing, and the other end is connected to the housing. In this application, the motor can output, by using the conductive bearing and the conductive component, charges accumulated in the output shaft, to eliminate a generated common-mode voltage.
