In the present invention a control circuit 63 controls an inverter circuit 62 on the basis of detection values from Hall sensors 61a, 61b, and 61c, and activates a rotor 50. After activation of the rotor 50, the control circuit 63 controls the rotational speed of the rotor 50 on the basis of the detection value from the Hall sensor 61a. A sensor pin 81 is arranged in a slot 48u between a forward winding part 46 and a reverse winding part 47 of a U-phase winding 49a. A sensor pin 83 is arranged in a slot 48v between the forward winding part 46 and the reverse winding part 47 of a V-phase winding 49b. A sensor pin 82 is arranged on one side in the axial direction with respect to the reverse winding part 47 of the U-phase winding 49a. The sensor pins 81 and 83 are positioned respectively at two first positions. |
