HIGH-SPEED MULTI-PHASE SYNCHRONOUS GENERATOR Russian patent published in 2016 - IPC H02K16/04 H02K21/14 H02K1/02 H02K3/50 

FIELD: machine building.

SUBSTANCE: invention relates to power engineering, in particular, to devices used in autonomous power supply systems. In the electric machine case there is a rotor and n stators with single-phase windings arranged on the stators. Permanent magnets are placed on the rotor, which is installed on additional gas-dynamic bearings, and stators with single-phase tooth windings arranged on them are made of separate segments of amorphous steel sheets, turned relative to each other through an angle $$\alpha =\frac{360}{m}$$ , where m is the number of phases, and are arranged so that the length of the projection of front parts l of the single-phase tooth winding of the opposed stator is compensated by arrangement in free space between stators, angle α between phases of output voltages of the generator is achieved by shifting the stators and magnets on the rotors relative to the corresponding stator.

EFFECT: technical result is decreased losses of eddy currents and reversal magnetization, mechanical stability at critical frequencies.
