A motor structure for varying a counter electromotive force is provided. The motor structure includes a rotor that is fixed annularly and concentrically to a radially outside from an exterior circumferential surface of a shaft of an electric motor and has a permanent magnet, and a stator that has coils positioned on the interior side of a motor housing and on the concentrically exterior side with the permanent magnet of the rotor. Further, the coils are positioned spaced apart from each other at predetermined intervals. A drive unit moves the stator in the axial direction of the shaft to vary the interlinkage flux, by varying an area that the magnetic flux of the permanent magnet of the rotor passes through the coils of the stator.
