The rotating electric machine comprises a rotator (31) mounted on the main shaft and a stator so provided as to enclose the rotator. The rotator has a first rotator section (32) producing a torque in the circumferential direction of the main shaft or the torque and the supporting force and a second rotator section (33) producing a shaft supporting force outward in the radial direction of the main shaft. The first and second rotator sections are arranged in tandem along the main shaft.

In one embodiment, the cage conductors are arranged in four-pole closed circuits, the drive windings have four poles, and the position control windings have two poles. In an alternative embodiment, the cage conductors may be arranged in two-pole closed circuits, the drive windings have two poles and the position control windings have four poles.

    摘要： A flywheel for storing inertial energy is integral with a rotor which is rotatable around a stator. The stator has main windings that provide a number of poles for rotating the rotor and auxiliary control windings that provide a number of poles different from the number of poles provided by the main windings. When currents are supplied to the main windings, the rotor and hence the flywheel are rotated. When control currents are supplied to the auxiliary control windings, radial forces acting on the rotors are generated thereby to support the rotor out of contact with the stator.
