Abstract :
Accurate induction motor parameter estimation is crucial for electrical drives. This paper presents a methodology enabling accurate estimation for induction motors response on pulse-width modulation inverter supply based on magnetic field analysis. Consideration of variations of magnetizing and iron loss parameters with loading in conjunction with harmonic iron loss associated to leakage inductances is essential for the estimator precision.
