Abstract: This paper introduced the design of a three-phase induction motor of 15 W, presented the demands of this induction motor. The inner diameter and length of the armature and the air gap length were determined firstly. The slots number of the armature and the cage rotor were selected to reduce the additional loss，vibration and noise. The shape of the armature slot and cage slot were chose respectively. The single layer concentrate full pitch winding was employed. The calculation results show the design scheme can meet the demands of the three-phase induction motor of 15W.
