Abstract
It is an object to detect the axial position of a rotor without using a sensor. A method for detecting the position of a motor including a rotor and a stator around which armature windings of a plurality of phases are wound is provided, wherein a position detecting coil is disposed on one axial end face of a stator core, an induced voltage generated in the position detecting coil is detected, and the axial position of the rotor is detected on the basis of the detection result.
