ELECTRIC MACHINE APPLIANCE Russian patent published in 1995 - IPC

FIELD: electric engineering. SUBSTANCE: device has synchronous machine and two single-pole machines. Synchronous machine has stationary armature of synchronous machine with magnetic circuit and winding and inductor which is made as hollow ferromagnetic cylinder with slots filled with rods with high conduction and non-magnetic insertions. Armature of synchronous machine is mounted coaxial to second magnetic circuit, which is built up of laminations, and additional armature winding. First unipolar machine has magnetic circuit with excitation coil and armature shaped as hollow ferromagnetic cylinder with short-circuited rings and liquid-metal terminals. Armature of first unipolar machine serves as inductor of synchronous machine. They are shaped as first hollow ferromagnetic cylinder, which is mounted in first ring pressurized chamber filled with inertial gas. Second unipolar machine has magnetic circuit of inductor with excitation coils, armature which is shaped as hollow ferromagnetic cylinder with rods, short-circuited rings and liquid-metal terminals. Said armature is mounted in second pressurized ring chamber. Ferromagnetic rotor has slots. EFFECT: increased functional capabilities. 6 cl, 4 dwg
