Abstract
The per-phase equivalent circuit (EC) of three-phase, squirrel-cage, induction motors (SCIMs) is used to simulate their performance and for example to set motor control parameters in variable-speed drives. In this chapter, a new method based on a stochastic approach is applied to determine the EC parameters of IE1-, IE2-, IE3- and IE4-class SCIMs on the basis of motor nameplate and catalogue data, and the simulated motor efficiency, power factor and current curves, as a function of slip, are compared to those obtained with two deterministic methods, namely, the IEEE 112 F/F1 standard method (traditional method), based on the no-load and locked-rotor tests, and the method proposed in (Bortoni’s method), based on the motor nameplate and catalogue data. The proposed method is relatively fast and may lead to better results when compared to the deterministic methods.
