摘要： A rotating electric machine in which an adequate magnetic supporting force can be produced even when the gap length of the rotator is long. 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.

摘要： An axial motor includes a rotor arranged between a pair of stators with coils. In the rotor, a plurality of permanent magnets sandwiched between pairs of first magnetic materials and a plurality of second magnetic materials are alternately arranged in a rotation direction while gaps are provided therebetween. Since the permanent magnets are sandwiched by the first magnetic materials in the thus constructed axial motor, a field-weakening control can be performed. Since the second magnetic materials are provided, a reluctance torque can be generated. Further, since the gaps are provided, more magnetic fluxes generated from the permanent magnets can be caused to flow toward the coils. Therefore, the thus constructed axial motor can achieve a higher output, higher torque, higher efficiency, and miniaturization.
