    摘要： A generator device has a reluctance generator. The reluctance generator comprises stator coils and an I-shaped rotor. The stator coils includes a winding phase for being supplied with a 90.degree.-leading armature current to generate a no-load induced electromotive force. The I-shaped rotor has an extremely small magnetic reluctance in a first direction normal to a rotational axis thereof and a large magnetic reluctance in a second direction normal to the first direction.

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.
