SYNCHRONOUS MOTOR WITH MAGNET GEAR REDUCTION Russian patent published in 2015 - IPC H02K19/00 

FIELD: electricity.

SUBSTANCE: synchronous motor comprises a housing (1) and end shields (2, 3). Rings (4, 5) of the stator pack are installed at them. At the ring (4) there are six teeth (6) with coils (7). Four permanent magnets (8) are installed at the bushing (9) of the fast-rotating rotor. The stator discs (10) are fixed at the stator (11) bushing. The slow-rotating rotor discs (12) are installed at the bushing (13). The fast-rotating shaft (14) is supported by bearings (16, 18), and the slow-rotating shaft 15 is supported by bearings (17, 19). The bearings (16, 17) are installed at end shields (2, 3) while bearings (18, 19) are installed at the bushing (20) of the bearings related to the stator disc (10). Numbers of ferromagnetic elements at the stator disc z_s and at the rotor disc z_r are linked by equation z_r=z_s±2p, and angular dimensions of ferromagnetic elements in the stator discs and slow-rotating rotor discs are different.

EFFECT: fabricability of the design and larger rotation rate of the motor, its reliable operation at stable basis.
