Rotor, method of manufacturing the same and rotary machine

摘要

A rotor has magnets (1) segmented in a circumferential direction of a periphery of a shaft (3), wherein magnetizing directions of the segmented magnets (1) continuously vary, and a non-magnetic material or a ferromagnetic material (4) is interposed in a circumferential gap between the segmented magnets (1). 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 (3) and magnetizing the segmented magnets (1). Still further, a rotary machine uses the rotor. <IMAGE>
