LOW-SPEED MULTIPOLE SYNCHRONOUS GENERATOR

摘要

The invention relates to electrical engineering, specifically to the design of multipole synchronous generators and can be used widely in particular in wind energy installation structures. The generator comprises a stator in the form of n-shaped segments with a winding formed from stator coils arranged with one coil per pole and combined into different coil groups, as well as a rotor with permanent magnets arranged on the rim along the rotor. The rotor is in the form of a disk with inserts consisting of permanent magnets fixed alternately relative to the direction of magnetization, wherein the permanent magnets on the rotor are mounted with a circumferential shift relative to the yokes of the stator coils in such a way that every 10th magnet or yoke of the stator coil is arranged opposite one another depending on which poles there are more of. The proposed synchronous generator has a significantly lower mass in comparison with the prior-art technical solution.
