UA110985C2 - Synchronous generator with permanent magnets - Google Patents

Abstract

The invention relates to electrical engineering and can be used in the construction of synchronous generators with permanent magnets, in which the voltage regulation when the load changes or the heating of the machine is performed by flow control of the excitation due to the change in the magnetic resistance circuit of the leakage flux. The basis of the invention is to simplify the design and improve energy performance. The problem is solved in that in the synchronous generators with permanent magnets, stator with winding, rotor with permanent magnets of the type "asterisk", pole shoes, which are installed on each magnet of the at least one side and exit over its active length. the shunt magnetic circuit made in the form of a package of rings, the bias winding, are mounted stationary and placed under overhangs, pole shoes, a magnetic core shunt packet is divided along a rotor axis, at least two discs mounted on a massive ferromagnetic glass, between which are mounted the coil magnetization, the distance between the end face of the active length of the rotor and the middle disk is more than double the size of the air gap between the inner surface of departures of the pole shoes and the outer surface of the discs.
