Winding Structure of Rotating Electric Machine

A winding structure of a rotating electric machine, comprising:

• a core body having teeth;
• and
• a winding portion wound around the teeth of said core body, wherein
• said winding portion has a first coil group and a second coil group,
• said first coil group and said second coil group are connected in parallel,
• said first coil group includes a plurality of first coils connected in series,
• said plurality of first coils are wound oppositely in direction by turns in the order in which said first coils are connected in series, said plurality of first coils are arranged in the manner that one coil set and the other coil set of said plurality of first coils are spaced apart in the circumferential direction of said core body and are opposite to each other in the radial direction of said core body, and each of said one coil set and said other coil set spaced apart from other includes a plurality of said first coils arranged to be adjacent to each other in the circumferential direction of said core body,
• said second coil group includes a plurality of second coils connected in series, and
• said plurality of second coils are wound oppositely in direction by turns in the order in which said second coils are connected in series, said plurality of second coils are arranged in the manner that one coil set and the other coil set of said plurality of second coils are spaced apart in the circumferential direction of said core body and are opposite to each other in the radial direction of said core body, and each of said one coil set and said other coil set spaced apart from other includes a plurality of said second coils arranged to be adjacent to each other in the circumferential direction of said core body.
