Document Type and Number:
Japanese Patent JP2522323
Kind Code:
B2
Abstract:
PURPOSE:To provide a direct relation between the control current to be passed to coils and generation power by passing permanent current to an annular superconductor and passing control currents to the coils so that repulsive force and attraction force are generated by the magnetic fields generated by the same. CONSTITUTION:The 1st and 2nd coils 2, 3 are disposed on both sides at both ends of the annular superconductor 1. The permanent current is passed to the superconductor 1 and the currents reverse from each other are supplied to the 1st and 2nd coils 2, 3 by a power amplifier 11, a PID controller 12, etc. The current flowing to the coils 2, 3 are outputted as the load measurement value of the load P acting on a lever 5.
