ABSTRACT:
Method and apparatus are provided for a stored magnetic field in a superconducting, rotating electrical machine. The apparatus includes a cylinder of superconductive material in which a magnetic field is trapped. The trapped magnetic field forms a magnetic circuit with an armature winding in the machine. The apparatus further includes means for generating a magnetic pattern field in the superconductive cylinder and means for cooling the cylinder so that a magnetic field can be trapped therein. The apparatus has application in both motors and generators and in both rotating and stationary magnetic fields used therein.
