20130119810 | ELECTRIC ROTATING MACHINE - The present invention provides an electric rotating machine capable of providing a high quality and efficient machine operation with reduced oscillation and noise by lowering torque ripple. The electric rotating machine includes a stator having a plurality of teeth facing a rotor, and a plurality of slots providing spaces for winding coils around the teeth. The rotor has a pair of permanent magnets embedded therein and located in a “V” shape configuration. Six slots of each set of the plurality of slots face one magnetic pole formed by the permanent magnets of each pair and the adjacent flux barriers. The plurality of teeth includes long teeth and short teeth. The distance xL between each of the long teeth and the rotor and the distance xS between each of the short teeth and the rotor meet the condition 0.1≦(xS−xL)/xL≦0.3. | 05-16-2013 |
20130193783 | ELECTRIC ROTATING MACHINE - An electric rotating machine includes a stator having a plurality of stator teeth facing a rotor. The rotor has a plurality of pairs of permanent magnets. Permanent magnets of each pair are located in a “V” shape configuration and form a magnetic pole. Every other tooth of the plurality of stator teeth is a long stator teeth and an adjacent tooth is a short stator teeth. Adjusting recesses formed in the rotor are at symmetrical, about a d-axis of each magnetic pole, locations in a way that each of the adjusting recesses has a width made equal to a width of one of the stator teeth and their deepest levels are equidistant from a d-axis of the magnetic pole in one and the opposite circumferential directions angularly about the axis of the rotor by 56° in electrical degrees. | 08-01-2013 |
20140091664 | INTERIOR PERMANENT MAGNET ELECTRIC ROTATING MACHINE - An electric rotating machine comprises a stator adapted for receiving stator windings; a rotor rotatable relative to the stator; permanent magnets in the rotor forming magnetic poles; and apertures with a low permeability. Each aperture is for that portion of one of the permanent magnets located in a predetermined range which would generate magnetic flux lines in such directions as to cancel magnetic flux lines emanating from the stator in the neighborhood of a direct axis of one of the magnetic poles if the permanent magnet were located in the predetermined range. | 04-03-2014 |
