Abstract :
A frequency-domain analysis of an induction machine is presented. The model is voltage driven and has the capability of analyzing series or parallel circuits and unbalanced conditions. The rotor bars are treated as circuits and the end ring segments are included in the analysis. By using a frequency-domain solution as the starting point for the transient finite-element-method (FEM) solver, the computation time required to reach steady state can be significantly reduced. The computation time required for a transient solver is investigated with the frequency-domain solution and without the frequency-domain solution. A method for the calculation of equivalent-circuit parameters based on simulated locked rotor tests is suggested. The results obtained have been used to initialized a time-domain solution and to generate a frequency-response plot
