摘要： A rotor has magnets segmented in a circumferential direction of a periphery of a shaft, wherein magnetizing directions of the segmented magnets continuously vary, and a non-magnetic material or a ferromagnetic material is interposed in a circumferential gap between the segmented magnets. Further, a method of manufacturing a rotor comprises steps of arranging coils so that a longitudinal direction of each of the coils is along an axis of the shaft and magnetizing the segmented magnets. Still further, a rotary machine uses the rotor.

The number of claws is equal to the number of permanent magnets, and magnet flux in a direction orthogonal to a center axis of the magnetic pole of the permanent magnet at right angles in electric angle is larger than magnetic flux in the center axis direction generated between neighboring permanent magnets. Metal interpoles are provided between neighboring permanent magnets.
