RESONANCE-TUNED ELECTRIC DRIVE Russian patent published in 2007 - IPC H02K57/00 

FIELD: electrical and electromechanical engineering; electrical machine manufacture.

SUBSTANCE: proposed resonance-tuned electric drive has first electrical machine incorporating stationary magnetic circuits disposed on stator and movable magnetic systems mounted on rotor. Second electrical machine has stationary magnetic systems disposed on base and movable magnetic systems disposed on facility displaced relative to base. Running-winding leads of first pairs of magnetic-circuit windings in stationary and movable magnetic systems of first-machine rotor are connected to leads of differentially connected running windings in movable magnetic system of second electrical machine and to capacitor leads to form resonance-tuned circuits functioning in current resonance mode.. Running-winding leads of second pairs of magnetic-circuit windings in rotor stationary and movable magnetic systems of first electrical machine are connected to leads of respective differentially connected running windings in stationary magnetic systems of second electrical machine and to additional capacitor leads to form resonance-tuned circuits functioning in current resonance mode. First leads of control windings in stationary and movable magnetic systems of first-machine stator and rotor as well as those of magnetic circuits in stationary and movable magnetic systems of second electrical machine are connected to leads of at least one control signal generating unit.

EFFECT: reduced size, mass, and power input, enlarged functional capabilities due to controlling one of electrical machines irrespective of motion speed of other-machine movable magnetic systems, as well as due to energy transfer from one electrical machine to other.
