PROBLEM TO BE SOLVED: To provide a concentrated winding motor that prevents displacement of coil bobbins to a rotor side due to the temperature or vibration of the motor.SOLUTION: In a concentrated winding motor, stator teeth 21, 221, 321, and 421 are formed that protrude from respective inner side surfaces 20a, 220a, 320a, and 420a of stators 20, 220, 320, and 420 to a side of a rotor 8. Cylindrical coil bobbins 30, 230, 330, and 430 are put on the respective stator teeth 21, 221, 321, and 421 from the side of the rotor 8, namely from respective protruding ends 21a, 221a, 321a, and 421a, and are mounted to the respective stator teeth 21, 221, 321, and 421. Metal displacement prevention means 40, 50, 60, 223, 323, and 423 are provided that prevent displacement of the respective coil bobbins 30, 230, 330, and 430 to the side of the rotor 8. |
