Abstract

The paper comprehensively describes the simulation of a 1000kW/18900rpm wound-rotor synchronous machine (WRSM) by using the 2D transient finite element (FE) analysis method. The magnetic fields, the iron losses, the electromagnetic torque and the terminal characteristics of the prototype machine are investigated. The q-axis inductance L_q and the d-axis inductance L_d of the sample machine are predicted in analytical models. All studies indicate that the wound-rotor synchronous machine is potential to apply in high speed generator or motor application.
