Finite Element Analysis of 1 MW High Speed Wound-Rotor Synchronous Machine

摘要

A 1000 kW/19 200 rpm wound-rotor synchronous machine has been designed as a draft based on 2-D transient finite-element method (FEM). The magnetic fields distribution, the iron losses, the electromagnetic torque and the terminal characteristics of the prototype machine are investigated in this paper by using 2-D finite element analysis. The $d$-axis inductance $L_{d}$ and the $q$-axis inductance $L_{q}$ 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.
