We fabricated and tested an axial-type motor with a Bi-2223 bulk to investigate its applicability. The motor was immersed in liquid nitrogen with zero-field cooling method. Load and locked rotor tests were carried out in a rotating magnetic field at 60 Hz frequency. Load tests showed that the fabricated motor does not reach synchronous speed, and torque declines with increasing rotational speed. These properties are similar to those of induction motor with high rotor resistance. On the other hand, locked rotor test indicates that the torque vs. magnetic field characteristics is qualitatively described by the area of hysteresis loop which is measured on a bulk surface with a hall sensor. That is, the fabricated motor shows both characteristics of conventional induction and hysteresis motors. (C) 2002 Elsevier Science B.V. All rights reserved.
