ELECTRICAL MACHINE Russian patent published in 2010 - IPC H02K16/02 

FIELD: electricity.

SUBSTANCE: electrical machine comprises stator with winding, inner rotor with output shaft installed in bearings, intermediate rotor covering inner rotor, on inner surface of intermediate rotor there are windings arranged, shaft of intermediate rotor is arranged as hollow, inside there is inner rotor shaft, besides bearings arranged on shafts of inner and intermediate rotors are arranged coaxially to their axis of rotation. On outer surface of intermediate rotor there are groups of permanent magnets arranged with alternating polarity, and generator winding of stator is multi-phased.

EFFECT: increased efficiency of device operation in wide range of inner rotor output shaft rotation speed change due to controlled redistribution of coaxial rotors rotation speeds, production of permanent output power with control of its rotation speed, and expansion of functional capabilities.
