<p>PROBLEM TO BE SOLVED: To provide a small-sized electric motor capable of reducing cost of manufacture without deteriorating the wire connection workability.SOLUTION: A coil 12 is wound around each tooth part 64 by a concentration winding system to form a small coil 81 with a three-phase structure. Terminal parts of the respective small coils 81 adjacent in a circumferential direction are connected with each other to form a small coil group configured by connecting a plurality of small coils 81 in series. Further, two small coil groups are electrically connected in parallel to form three phase coils. A harness is connected to one end of each phase coil to connect the respective phase coils by delta connection. Two terminal parts 81a and 81b of the small coil 81 extracted from a predetermined split core 61 are made cross each other to form a crossing part 68 at one end of the split core 61 in an axial direction, and this crossing part 68 is arranged on an inner wall part 15 side from an outer wall part 16. The two terminal parts 81a and 81b are connected with the terminal parts 81a and 81b of the small coil 81 formed in the other split core 61 arranged on an opposite side to the extracted side.</p> |
