Title:
SUPERCONDUCTING MOTOR
Document Type and Number:
Japanese Patent JP2012139099
Kind Code:
A
Abstract:

To provide a superconducting motor that can use a superconducting coil as a field side stator without complicating its shape.

The superconducting motor includes an armature side rotor, and the field side stator arranged around the armature side rotor. The field side stator includes: a cylindrical field coil comprising a pancake coil or solenoid coil formed by a winding of a strip of superconducting conductor; a first yoke and a second yoke arranged at both axial ends of the field coil; N polarity inductors projecting from an inner circumference of the first yoke; and S polarity inductors projecting from an inner circumference of the second yoke. The N polarity inductors and the S polarity inductors are circumferentially spaced to leave magnetic paths between an inner circumference of the superconducting field coil and the armature side rotor.
