Temperature and Frequency Effects in a High-Performance Superconducting Bearing

摘要

A high-temperature superconducting (HTS) bearing was fabricated and tested by itself and as a component in a 1-kWH and a 10-kWh flywheel energy system (FES). The rotational losses of the HTS bearing as a function of rotational rate and HTS temperature were determined. The 1-kWh FES was tested with a motor/generator and with an eddy current clutch to determine the motor/generator losses.
