SYNCHRONOUS MOTOR WITH MAGNETIC REDUCTION Russian patent published in 2016 - IPC H02K19/06 H02K49/06 

FIELD: engines and pumps.

SUBSTANCE: invention can be used as compact “motor reducer” in mechanical systems with large service life at impact loads, for example as motor-wheels of environmentally clean cars. Synchronous motor with magnetic reduction includes housing 1 and end shields 2, 3. Rings 4, 5 of stator pack are installed at them. On ring 4 there are six teeth 6 with crowns and with coils 7, and on ring 5 there are wedge-shaped ledges 21. Four permanent magnets 8 are installed on bushing 9 of fast-rotating rotor. Discs 10 of stator are fixed on sleeve 11 of stator. Slow-rotating rotor discs 12 are installed on sleeve 13. Fast-rotating shaft 14 is supported by bearings 16, 18, and slow-rotating shaft 15 is supported by bearings 17, 19. Bearings 16, 17 are installed at end shields 2, 3 while bearings 18, 19 are installed at bushing 20 of bearings related to stator disc 10.

EFFECT: creation of synchronous electric motor with advanced design and improved power parameters.
