Abstract

A stator of a wire connection structure is capable of producing an unlimited number of non-integer turns. This stator is made by turning back first to sixth conductors on the outside of an end face of a stator iron core, and by mounting them in slots at a predetermined slot pitch in each of U, V and W phases. The sixth conductor is divided into two 0.5 turns coils. Connecting in parallel 1.5 turns of each coil, in which the second conductor and a first of the coils are connected, and 1.5 turns of a coil in which the fourth conductor and a second of the coils are connected, forms a 1.5 turns coil. Connecting in series the 1.5 turns coil, and 3 turns of a coil formed by connecting in series the first conductor, the third conductor, and the fifth conductor forms a 4.5 turns coil.
