The invention provides a motor, an electric power steering system and a vehicle, and the motor comprises a housing; the rotor is provided with a rotating shaft arranged along the central axis; the stator is arranged in the shell, and the stator and the rotor are arranged oppositely in the radial direction; a busbar; a first bearing chamber is arranged on the bottom wall of the shell; a second bearing chamber is arranged on the top wall of the shell; the motor further comprises a first bearing and a second bearing, the first end of the rotating shaft penetrates through the first bearing, and the second end of the rotating shaft penetrates through the second bearing. The stator comprises a stator iron core, a stator framework and a stator winding, the stator framework extends out of the first end of the stator iron core and the second end of the stator iron core in the axial direction of the motor, and the busbar is connected with the part, extending out of the second end of the stator iron core, of the stator framework; the second bearing chamber overlaps at least a portion of the busbar in a radial direction of the motor. As the second bearing chamber and the busbar are overlapped along the radial direction, the axial length of the motor is reduced, and the size of the motor is reduced.

    本发明提供了一种电机、电动助力转向系统和车辆,其中,电机包括:壳体;转子,转子具有沿中心轴线配置的转轴;定子,设于壳体内,定子与转子径向对置配置;汇流排;壳体的底壁上设有第一轴承室;壳体的顶壁上设有第二轴承室;电机还包括:第一轴承和第二轴承,转轴的第一端穿过第一轴承,转轴的第二端穿过第二轴承;定子包括:定子铁芯、定子骨架和定子绕组,沿电机的轴向,定子骨架分别伸出定子铁芯的第一端和定子铁芯的第二端,汇流排与伸出定子铁芯第二端的部分定子骨架相连接;第二轴承室与汇流排的至少一部分沿电机的径向重叠。由于第二轴承室的与汇流排沿径向重叠,减少电机轴向的长度,减小电机的体积。
