The rotor core has a boss, a disc portion and a cylindrical part. The cylindrical part is connected with the disc portion and is continuous along the rotor shaft. The cylindrical part is formed with projections and recesses which are disposed alternately in a circumferential direction on the outer periphery thereof. Permanent magnets may be disposed in the recesses. The annular core is connected with outer peripheries of the projections of the cylindrical parts. By adopting the cylindrical parts and the annular core, diameter of the boss is enlarged.

摘要： Each permanent magnet formed in an open-letter shape is divided into a plurality of parts, the divided magnets are respectively fitted in open letter-shaped inserting portions, and ribs are respectively provided in dividing portions of the permanent magnets. Accordingly, it is possible to prevent the breakage of pole connecting portions at an outermost periphery of the rotor as adjacent inner peripheral-side permanent magnets directly come into contact with and push the outer peripheral-side permanent magnets. Alternatively, an annular nonmagnetic material is provided on an outer peripheral portion of the rotor so as to cover the open letter-shaped permanent magnets and magnetic material portions inside the open-letter portions, whereby the rotor core is made resistant against breakage, and the flux leakage is minimized.

摘要： A permanent magnet type electric rotating machine comprises a stator having a salient-pole concentrated winding, and a rotor disposed with a rotational gap, and having a plurality of permanent magnets arranged and fixed in a circumferential direction inside, and an auxiliary salient pole provided between the permanent magnets. A ratio of the number of poles for the rotor and the number of slots for the stator is 2:3 and, when a slot pitch of the stator is nulls (electrical angle), an angle null (electrical angle) made by a circumferential width of the permanent magnet in the surface of the stator side with an axis of the rotor is set at nullnullnnullnulls/2null8nullm (nnull1 or 2, and mnull1, 2 or 3). Thus, pulsation torque, cogging torque or the waveform distortion of a no-load induced voltage is selectively reduced as occasion demands.

摘要： A motor or a generator which has permanent magnets on a moveable member effectively reduces eddy current loss in the permanent magnets. A permanent magnet 1 which is provided for the moveable member of a motor or a generator, for example the rotor of a rotating motor, is divided into magnet sections (1A-1E) having divided widths (t1-t5) in response to the rate of change in the flux density in each divided magnet. Thus the eddy current loss in each magnet section (1A-1E) can be substantially equalized.
