DECREASED DRAG ELECTRIC MACHINE WITH DUAL STATOR AND DISTRIBUTED HIGH FLUX DENSITY SLOT ROTOR PAIRS

摘要

A method and apparatus for reducing drag in an electric generator are disclosed. Members of slot rotor pairs are distributed along the inner and outer periphery of sections of a stator having slots to accommodate induction windings. The members of the slot rotor pairs include slot rotors having at least one pair of pole sections of a first and a second magnetic polarity. The members of the slot rotor pairs are rotated in a synchronized manner such that a first one of the pole sections of the first member with a first magnetic polarity and a second one of the pole sections of the second member having a second magnetic polarity are aligned with the slots to provide maximum flux density in the induction windings to induce a current flow. The inner peripheries of the first and second stator sections are adjacent to each other. The slots of the stator sections are axially aligned. The first member and the second member of the respective slot rotor pairs are aligned with the aligned slots.
