摘要： An electric motor includes a rotor assembly including a rotor shaft, a rotor body fixedly coupled to the rotor shaft, and a plurality of magnets coupled to the rotor body. The electric motor also includes a stator assembly at least partially received within the rotor body. The stator assembly includes a stator mount including a stator support portion and a motor support portion. The stator assembly also includes a stator core assembly fixedly supported by the stator mount, the stator core assembly defining a central bore that receives the rotor shaft and the stator support portion. The electric motor also includes a bearing having an outer race and an inner race, the outer race being supported by the stator core assembly, and the inner race supporting the rotor shaft for rotation relative to the stator assembly. The stator core assembly further defines a bearing pocket adjacent to the central bore.

摘要： This application provides an axial motor, a powertrain, and an electric device. The axial flux motor includes a motor shaft, a double-row angular contact ball bearing, and a stator. The double-row angular contact ball bearing is sleeved or the motor shaft and is fixedly connected to the motor shaft through a bearing inner ring of the double-row angular contact ball bearing. The stator is sleeved or the motor shaft through the double-row angular contact ball bearing, and the stator is fixedly connected to a bearing outer ring, so that the motor shaft can rotate relative to the stator. In this application, the double-row angular contact ball bearing is used in the axial motor, and due to a strong axial bearing capability of the double-row angular contact ball bearing, the double-row angular contact ball bearing can bear axial force generated through interaction between the stator and a rotor. Therefore, durability of the axial flux motor is improved. In addition, because different models of double-row angular contact ball bearings have different clearances, the stator and the motor shaft may be adapted by selecting the models, and there is no need to manually adjust a bearing clearance. Therefore, mounting difficulty is effectively reduced, and production efficiency is improved.
