PROBLEM TO BE SOLVED: To improve a efficiency of a motor by filling a space for needle insertion. SOLUTION: Needles 2a to 2f of a winding apparatus are inserted into all slots on an inner rotor type stator core 1 with three-phase 6-slots and are respectively reciprocated several times in the axial, circumferential, and radial directions of the stator core 1 to simultaneously conduct winding around all the slots. After windings U1a, V1a, W1a, U2a, V2a, and W2a for a first layer are formed, windings U1b, V1b, W1b, U2b, V2b, and W2b for a second layer are formed so as to fill spaces 3 between the respective windings while the respective needles 2a to 2f are being retracted from the most protruding condition. |
