HTS electrical machines with BSCCO/Ag composite plate-shaped rotor elements

摘要

This work relates to the investigation of electrical machines having advanced BSCCO/Ag-sheathed elements which are being produced by the well-known technology "powder in tube". That foliate HTS material is being considered to be used in three types of electric machines: reluctance and hysteresis motors and synchronous machines with "trapped magnetic flux". Depending on the thickness, quantity of BSCCO layers and filling factor they are being produced as thin and thick ones. Several small-scale experimental models of the above-mentioned types were developed and tested in liquid nitrogen. The output power rating of reluctance motors with thin and thick HTS elements are 3 and 4 kW respectively. "Trapped field" machine was tested in generator mode for open circuit operation. The value of obtained magnetic flux density in the air gap is 0.8 T. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 2]
