Comparison of characteristics of large-scale high-Tc superconducting synchronous motor and conventional iron-core motor

The large high-Tc superconducting synchronous motors are expected to become cost-competitive with the conventional iron-core motors owing to the energy consumption and its small size and lightness compared to the copper field winding motors. The geometric and electromagnetic factors affect the performance of the high-Tc superconducting motors. The machine equations can be used directly to predict the performance of the motors by transforming the variables to a rotor reference frame. Computed results of the characteristics of the high-Tc superconducting synchronous motor and conventional motor are compared.
