Motor, driving device and vehicle

The utility model provides a motor, a driving device and a vehicle. The motor includes a stator, a rotor, and a cylindrical housing that holds a stator core of the stator. A plurality of connecting parts extending in the axial direction are arranged on the peripheral face of the machine shell in the circumferential direction, and a first rib part with the radial amplitude is further arranged between every two connecting parts on the peripheral face of the machine shell; and the radial amplitude of the first rib part is increased along with the distance from the connecting part. According to the structure, vibration and noise caused by torsional resonance of the stator core are reduced. 本申请提供一种马达、驱动装置以及车辆。所述马达具有定子和转子以及筒状的机壳，所述机壳保持所述定子的定子铁芯。在所述机壳的外周面沿周向设置有多个沿轴向延伸的连接部，在所述机壳的外周面的每两个所述连接部之间还设置有具有径向幅度的第一肋部；所述第一肋部的径向幅度随着远离所述连接部而增大。由此结构，降低了由于定子铁芯的扭转谐振而引起的振动和噪声。
