  • Patent number: 9843247
    Abstract: This rotating electric machine has a rotor, stator core, field windings for multiple poles, and armature windings for the multiple poles. The rotor is rotatably supported about a shaft. Convex-shaped multiple salient pole sections are formed on the outer circumference of the rotor while arranged in the circumferential direction. The stator core is provided along the outer circumference of the rotor with an air gap from the rotor. Convex-shaped multiple teeth are formed on the inner circumference of the stator core while arranged in the circumferential direction. The field windings for the multiple poles are wound around each of the multiple teeth while insulated from the field windings.

  • Patent number: 9450522
    Abstract: A field control device for a synchronous rotating machine includes: a target operating condition input unit; a first subtraction unit; a final-control-quantity control computation unit that accepts the final-control-quantity deviation and outputs a field-current correction demand value; an anticipatory computation unit that outputs a field-current anticipatory demand value based on the operating condition demand values input; an addition unit that adds the field-current correction demand value and the field-current anticipatory demand value; a second subtraction unit; and a field-current regulation device that adjusts the field current based on the field current deviation.
