Abstract

PURPOSE:To contrive to miniaturize and lighten an apparatus and to reduce its loss and enhance its efficiency by replacing a partial or full silicon steel plate with a high-temperature superconductive shielding plate. CONSTITUTION:An electrical rotating machine is composed of a rotor 1 housing a field winding 6, a silicon steel plate laminated core 4 housing a stator winding 2 and a high-temperature superconductive shield 5 provided round the outer periphery of said silicon steel plate laminated core 4. When a field flux generated by the field winding 6 radially goes through the silicon steel plate laminated core 4 and is going to pass through said high-temperature superconductive shielding plate 5, overcurrent cancelling said field flux flows within the shielding plate 5 to shield said field flux from leakage to the outside. Thus, it is possible to accomplish the miniaturization and lightening of said machine and the reduction of its loss and enhancement of its efficiency.
