Motor stator and motor

The invention discloses a motor stator and a motor. The motor stator comprises a stator tooth part and a stator yoke part. The stator tooth parts are enclosed to form a central groove. The stator yoke part is arranged around the stator tooth part by a circle, the stator yoke part is provided with a yoke part vibration reduction groove, and the yoke part vibration reduction groove is arranged in a manner of extending along the circumferential direction of the stator tooth part. According to the motor, the stator yoke part of the motor is slotted, so that the vibration level of the surface of the shell is obviously reduced, the vibration noise is effectively reduced, and the motor has a certain reference value in the design of the motor with low vibration noise. 本发明公开一种电机定子及电机，电机定子包括：定子齿部和定子轭部。定子齿部围合形成中心槽。定子轭部绕所述定子齿部一周设置，所述定子轭部上设置有轭部减振槽，所述轭部减振槽沿所述定子齿部的周向延伸设置。本申请中，通过在电机的定子轭部开槽，使得机壳表面的振动水平得以明显降低，有效地削减了振动噪声，在低振动噪声的电机设计中具有一定的参考价值。
