Abstract: An 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 on 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 on 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, the double-row angular contact ball bearing can bear axial force generated through interaction between the stator and a rotor.
