A rotary electric machine capable of optionally adjusting output
characteristic and an electric motor vehicle using the rotary electric
machine are provided.A rotary electric machine is constituted with: a
rotary shaft 220; a rotor 40 connected to the rotary shaft 220; a stator
31 placed opposite the rotor 40; a stepping motor 60 serving as an
adjusting motor for adjusting the position of the rotor 40 relative to
the stator 31 in the rotary axis direction; and a movable member 47 or
the like that is engaged to the rotor 40 and converts the rotation of the
adjusting motor 60 into the displacement of the movable member 47 in the
axial direction of the rotary shaft 220.
