Dynamic performance and design of a high-Tc superconducting synchronous motor

The electrical and electromechanical behavior of the high-Tc superconducting synchronous motor has been investigated. The rotor of a high-Tc superconducting synchronous motor is equipped with the high-Tc superconducting field winding and one or more flux dampers. Due to magnetic asymmetries in the case of the salient-pole machine, reference frame theory has been used to establish the machine equations which explain the flux damper placed on the rotor of the motor. After a description of a motor design concerning the density of the high-Tc superconducting wire, computer traces are given to illustrate the complete dynamic responses in various modes of operation, which are calculated by using a detailed set of nonlinear differential equations.
