Abstract :
A new method for estimating the small-signal parameters of induction machines is presented. The data for estimation is produced by two-dimensional time-stepping finite element analysis (FEA). The method is applied to three different types of induction machines: a cage-induction, solid-rotor and slip-ring machine. The steady-state parameters of the induction machines are also estimated. This estimation is based on the time-harmonic FEA. The fitting results are good and the estimated parameters are physically reasonable
