A structure of a low-voltage sensorless motor is provided to accurately recognize position information of a rotor at an initial start state by winding a start winding around a stator. A stator(22) is formed in a body(21) of a sensorless motor, and has at least one phase. A drive winding(32) is wound around each stator for detecting a drive function. A start winding(31) is wound around each stator and has an impedance value larger than the drive winding. An inverter(33) is connected to the drive winding or the start winding. A switch(34) switches to selectively connect the inverter with the drive winding or the start winding according to a signal of the inverter. |
