ELECTROMAGNETIC GENERATOR

The invention relates to the field of electrical engineering, specifically to low-speed electrical generators, and can be used in particular in wind energy installations. In the proposed electromagnetic generator the rotor is equipped with permanent magnets (3, 4) and the stator comprises two parallel plates (5, 6), between which annular windings (7) are arranged. The rotor is formed from two parallel discs (1, 2) fixed to a shaft (10), with circular rows of said permanent magnets arranged on each of said parallel discs on surfaces facing one another, the polarity of said permanent magnets in each row alternating, while the poles of the permanent magnets in one row are turned towards the opposite poles of the permanent magnets in the other row. The annular windings (7) of the stator are inserted in pairs one inside the other and are in the form of isosceles trapeziums, the lateral sides (8, 9) of which are arranged radially relative to the axis (10) of rotation of the rotor. Sections (11, 12) of the annular windings (7) in the bases of the trapeziums arch out convexly, wherein the distance l between the sections of annular windings in the bases of the trapeziums exceeds the width b of the circular row of permanent magnets (3, 4), which adjoin one another in each circular row. The permanent magnets adjoin one another in each circular row by the adjacent lateral planes thereof. The technical result consists in increasing the power of an electromagnetic generator whilst maintaining the overall dimensions thereof.
