  • Patent number: 10622860
    Abstract: A drive motor for a vehicle includes: a stator and a rotor, in which the stator includes: stator teeth which are disposed between multiple slots, respectively, the multiple slots being formed at predetermined intervals in a circumferential direction corresponding to an outer circumferential surface of the rotor, and have a blocking portion which protrudes toward one of the slots disposed at both sides, the blocking portion formed at one side of an inner circumferential surface of each of the stator teeth facing the rotor, and a groove which is formed radially outward at an opposite side of the inner circumferential surface of each of the stator teeth; and opening sections each of which is in communication with the slot and formed between the blocking portion and the opposite side of the inner circumferential surface of the stator tooth adjacent to the blocking portion, and the slot is opened radially through the opening section.

  • Patent number: 10393185
    Abstract: A bearing for a drive motor is provided. The bearing includes an inner race that is coupled to a rotation shaft, an outer race that is coupled to a motor housing, and rolling members that are rotatably disposed between a raceway surface of the inner race and a raceway surface of the outer race. Additionally, a retainer is disposed between the inner race and the outer race and supports the rolling members at a predetermined interval along a circumferential direction. A conductive guide member is formed in each of the inner race and the outer race and forms a current path between the inner race and the outer race through the retainer.

  • Publication number: 20190181729
    Abstract: A ground structure of a drive motor is provided. The ground structure of the drive motor forms a current path of a motor housing and a rotation shaft. The structure includes a current carrying housing that is fixed to the motor housing and accommodates a least one end portion of the rotation shaft and a current carrying medium that has conductivity and is included in an inner space of the current carrying housing.
