Abstract
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.
Claims10
A rotor having magnets segmented in a circumferential direction of a periphery of a shaft, wherein magnetizing directions or magnetized directions of said magnets continuously vary, and a non-magnetic material or a ferromagnetic material is interposed in a circumferential gap between said segmented magnets.
A rotor having magnets segmented in a circumferential direction of a periphery of a shaft, wherein each of said segmented magnets has a polar anisotropy and is formed of a bond magnet or a sintered magnet containing a rear-earth element, and a non-magnetic material or a ferromagnetic material is interposed in a circumferential gap between said segmented magnets.
A method of manufacturing a rotor which has magnets segmented in a circumferential direction of a periphery of a shaft and a non-magnetic material or a ferromagnetic material interposed in a circumferential gap between said segmented magnets, wherein said segmented magnets are formed by flowing current in a direction along an axis of said shaft to magnetize said segmented magnets.
