MAGNETOELECTRIC GENERATOR

摘要

The invention relates to the field of electrical engineering, and specifically to low-speed electric generators, and may be used in wind-energy installations. In a magnetoelectric generator, a rotor is equipped with permanent magnets, and a stator contains two parallel plates having annular windings positioned therebetween. The windings are in the form of isosceles trapezoids, the lateral sides of which are positioned radially relative to the rotational axis of the rotor. The portions of the windings at the base of the trapezoid are curved in an arc. The rotor is comprised of two parallel discs secured to a shaft, each of which discs has annular rows of permanent magnets provided on their mutually facing surfaces, the polarity of which magnets alternates in each row. The poles of the permanent magnets of one row face the opposite poles of the permanent magnets of a different row, and are offset by half the width of the magnets. The annular windings are inserted one into another, forming modules, wherein the distance (l) between the portions of the annular windings at the bases of the trapezoids exceeds the width (b) of an annular row of permanent magnets. Positioned between the annular windings is an additional flat annular winding in the form of an isosceles trapezoid, the lateral sides of which are positioned in the same plane between the lateral sides of the other annular windings.
