SYNCHRONOUS ELECTRIC GENERATOR WITH MULTI-POLE COMBINED MAGNETIC SYSTEM WITH PERMANENT MAGNETS Russian patent published in 2019 - IPC H02K21/24 H02K16/04 H02K1/27 

FIELD: electrical engineering.

SUBSTANCE: synchronous electric generator with multi-pole combined magnetic system with permanent magnets comprises rotor made in form of disc from non-magnetic material with magnetic sections fixed on its periphery along circumference, and two stators arranged coaxially and parallel to each other on both sides of rotor. Stators consist of tape magnetic cores with coils located in its slots. Magnetic system of rotor represents alternating magnetic assemblies, each of which consists of four magnets and two H-shaped spacers made of magnetically soft material. All elements are located symmetrically relative to center of magnetic assembly in following order, counting from left to right: left H-shaped insert, in right slot of which there is a first magnet, magnetization axis of which is tangential and directed along direction of rotor movement, second and third magnets, magnetization axes of which are radial, have opposite direction, the fourth magnet is installed in the left slot of the right H-shaped spacer; at that, the magnetization axis of the fourth magnet is directed towards the axis of magnetization of the first magnet.

EFFECT: increased energy efficiency of generator.
