A motor winding structure includes a base plate is disclosed. The base plate includes a board having a winding unit. The winding unit includes a plurality of coils formed on the surface of the board by electroforming or layout. Each coil has a center, and includes an inner end adjacent to the center and an outer end distant to the center. Two adjacent coils are connected to each other via the inner ends. The winding unit further includes an insulating layer and a conducting layer. The inner ends of the two coils are connected to an electrical connection pad. The insulating layer is arranged on the board. The two adjacent coils are covered by the insulating layer. The conducting layer extends through the insulating layer and is connected to the electrical connection pads of the two coils. The two coils are connected to each other via the inner ends.
