A small axial-type BSCCO high-T-c superconducting motor cooled with liquid nitrogen has been fabricated and tested in terms of speed, torque and speed-torque characteristic curves. BSCCO bulky disk is used to be 120 mm in diameter and 8 mm thick, and two-pole concentrated armature winding is fed with the PWM inverter. The BSCCO machine could substantially operate as hysteresis motor. In the experimental motor, M-H characteristic curves at different local points of the BSCCO disk were not same, air-gap magnetic flux density was not completely sinusoidal, and viscosity losses existed due to liquid nitrogen, so that the motor could not rotate at synchronous speed. Performances have been evaluated and an equivalent circuit of the BSCCO-2223 bulk motor has been estimated from test results. (C) 2001 Elsevier Science B.V. All rights reserved.
