This paper describes a series of experiments investigating the operational characteristics of a high-Tc superconducting synchronous motor of five to six hundred watts capacity. In this experiment, ac 220V stator phase voltage and de 4A excitation current are used, and the synchronous speed runs at 1800rpm. Hall Sensors are installed on the pole face and at the side of the Ag/Bi-2223 high-Tc superconducting tape in order to analyze the effect of the time-varying magnetic field on the motor performance when the load changes its value. The experimental observations are compared with the theoretical predictions.
