ELECTRIC MOTOR

摘要

electrical engineering. SUBSTANCE: electric motor is essentially closed-cycle three-circuit mechanism incorporating following hydraulic machines arranged in tandem: axial-plunger pump and hydraulic motor. Pump is expansion device that functions to change low- potential pressure of gaseous working medium coming from evaporator into high pressure of liquid. Hydraulic motor serves to change high pressure of liquid medium coming from pump into mechanical energy for driving generator or mechanical device. Third (drain) circuit provides for complete tightness of mechanism and for elimination of working medium leakage. EFFECT: improved energy intensity, reliability, and tightness of electric motor systems. 1 dwg
