CONTROLLED ASYNCHRONOUS DRIVE WITH CASCADE AND COMMON ROTOR Russian patent published in 2015 - IPC H02K17/34 H02K17/16 H02K3/04 

FIELD: electricity.

SUBSTANCE: asynchronous drive with cascade and common rotor comprises two electric motors connected coaxially, which magnet systems are axial and placed in the same housing at the same shaft fixed horizontally in bearing assemblies of the housing. Stator of the first electric motor is fixed rigidly by its one side to the housing. Rotor of both motors are joined in a single structure comprising joined magnet core with radial slots placed at the left and right side of the rotor, wherein squirrel-cage winding placed with its turns passing from the left lock ring placed at inner left side of the joined rotor, then through the left slot, then through outer side of the rotor and finally through the right slot to the right lock ring placed at the right inner side of the joined rotor. Stator of the second electric motor is fixed rigidly and by its teeth is faced towards stator teeth of the first electric motor. Stator winding of the second electric motor is connected to variable resistors controlling change in rotation velocity and moment of the controlled electric drive with cascade.

EFFECT: reliability improvement.
