LINEAR INDUCTION MACHINE Russian patent published in 2000 - IPC

FIELD: linear induction pumps and linear-traction induction machines. SUBSTANCE: machine has flat magnetic core and coils relatively offset in active plane to form winding. Coils are not electrically interconnected and only inductively coupled. Capacitors are connected to coils to organize resonance-tuned circuits. One of resonance- tuned circuits is connected to single-phase voltage supply and current induced in circuit builds up magnetic flux which, in its turn, induces electric currents in adjacent tuned circuits. Currents induced in this way in electrically neutral resonance-tuned circuits build up magnetic fluxes shifted in time and in space and generating electromagnetic traveling field that sets conducting working body in motion. EFFECT: provision for producing traveling travelling field only in case of electromagnetic coupling between phase coils. 3 dwg
