The invention relates to a shaft assembly for a motor. The shaft assembly comprises: a shaft tube, a bearing, a shaft and at least two engaged rings. The shaft has an end and a slot. At least two engaged rings are disposed in the slot of the shaft, and comprise a first engaged ring and a second engaged ring. The first engaged ring is a metal material and the second engaged ring is a non-metal material. The material strength of the first engaged ring is larger than that of the second engaged ring. The first engaged ring can be utilized to support and position the shaft, and the second engaged ring can be utilized to cushion the shaft. Therefore, the problems of motor noise, rotor shift or even separating from the bearing can be resolved simultaneously so as to increase the stability of motor.
