Document Type and Number:
Japanese Patent JP6867669
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a superconducting motor which suppresses a phase deviation of a voltage and a current, and increases a power factor (cosφ).SOLUTION: A superconducting motor comprises: a rotator in which a permanent magnet is provided; a stator in which a coil 60 formed by a superconducting wire is provided in an N-phase (N is three or more arbitrary integer numbers); and an electric power source 120 for flowing an AC current having a predetermined phase difference to coils 61 and 62 of each phase excluding a coil 63 of a nth phase (n is an arbitrary integer number of 1 or less than n). In the superconducting motor in which the rotator is rotated to the stator by an AC magnetic field occurred in the coils 61, 62, and 63 by currents I, I, and Iflowing in the coil 60, and a magnetic field occurred in a permanent magnet, The n-phase coil 63 is connected to a voltage source 130, and the voltage source 130 outputs a voltage so as to eliminate an electromotive force occurred in the nth phase coil 63.SELECTED DRAWING: Figure 2
