    摘要: In a dynamo electric machine provided with a stator and a permanent magnet type rotor (2), on a circumferential surface of the rotor (2) p·n pieces of permanent magnet blocks (21) are disposed, herein p is number of poles of the rotor and n is an integer equal to or more than 2, and each of the permanent magnet blocks satisfies the following condition (1); (θi)-(θi+1) = (Ai·p/2)
    Wherein, when assuming that clockwise direction is plus, Ai is an angle formed between radial center lines of ith permanent magnet block and (i+1)th permanent magnet block, θi is an angle formed between magnetization direction of the ith permanent magnet block and the outward radial direction thereof, and θi+1 is an angle formed between magnetization direction of the (i+1)th permanent magnet block and the outward radial direction thereof.

    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.
