PROBLEM TO BE SOLVED: To provide an unconventional, epoch-making exciting coil structure which contributes to the miniaturization, weight reduction, and cost cutting of a motor, in a stator in which a plurality of teeth with magnetic poles on which exciting coils are wound concentrically are arranged in the circumferential direction. SOLUTION: The exciting coils 8u to 8w of the stator 2 are formed by rectangular wire coils 13a. In that case, the rectangular wire coils 13a are formed by winding a rectangular wire 13 to start winding the wire from outer circumferential side and to finish winding the wire at the outer circumferential side by alternately changing the winding direction of each step from the outer circumferential side to the inner circumferential side and from the inner circumferential side to the outer circumferential side with its wide width surface facing the circumferential surface of each of teeth 51, 62 of the stator 2 and each exciting coil of at least a part of magnetic poles is formed by a cassette coil 81 of the same rectangular wire 13.
