PROBLEM TO BE SOLVED: To control and maintain induced voltage within a proper range. SOLUTION: This motor/generator is constituted of a stator 1, a rotor 3 which receives torque relative to the stator 1 by magnetic mutual action received from the stator 1, and a position adjuster 16 which adjusts the axial directional position of the stator 1 to the rotor 3. The magnetic interaction between the rotor 3 and the stator 1 can be made changeable. Changeability like this corresponds to controlling of such various electrical and magnetic output variables as induced voltage of the stator 1 and the like independent of such control variables as rotating speed of the rotor, supply current to the stator and the like, and it allows a new technological evaluation of a generator and a motor/generator; especially it optimizes a superconducting bearing flywheel power storage. It is preferable that the stator is of coreless type. It is important that the position adjuster 16 has a locking function to fix the axial direction position to an arbitrary position. It can favorably be utilized for the superconducting bearing flywheel power storage.
