PURPOSE: To improve thrust property and also, materialize the low voltage and small capacity of a power source by constituting an LC resonance circuit of a variable capacitor unit and a superconductive linear induction motor, and adjusting the impedance of each phase independently for each phase thereby removing the current unbalance, and compensating the voltage of a power source by IC series resonance.
CONSTITUTION: Each component is connected so that the currents flowing to coils 1-6 of a superconductive linear induction motor may be the phase patterns of U, -V, W, -U, V, -W, and variable capacitor units C1, C2, and C3 are connected to each primary coil unit. And, a three-phase symmetrical power source 7 is connected, and the voltage is boosted until it being quenched, thus a linear motor is driven. Hereby, the voltage is compensated by an LC series resonance, and also impedance is equally adjusted independently for each phase, and a three-phase balanced current can be applied with low voltage and low capacity.
