Abstract
A control circuit controls, based on detection values of Hall-effect sensors, an inverter circuit to activate a rotor. After the activation of the rotor, the control circuit controls the rotational speed of the rotor based on the detection value of the Hall-effect sensor. A sensor pin is arranged in a slot between a forward-wound portion and a reverse-wound portion of a U-phase winding. A sensor pin is arranged in a slot between a forward-wound portion and a reverse-wound portion of a V-phase winding. A sensor pin is located on one side in an axial direction with respect to the reverse-wound portion of the U-phase winding. The sensor pins are located respectively at two first positions.
