ABSTRACT:
A winding of a motor is formed by coiling a wire around a slotless stator core with combination of troidal coiling and array coiling. The toroidal coiling is carried out in a manner such that the wire is coiled without any intersecting turns in one direction for the formation of the winding as it is coiled rotating spirally. By this coiling method, the accuracy of the position of the winding in the direction tangent to the surface of the stator core can be improved. The array coiling is carried out in a manner such that the winding is formed in layers that are stacked on one another. By this coiling method, the accuracy of the position of the winding in the direction normal to the surface of the stator core can be improved. Thus, the overall thickness of the winding can be made uniform.
