Parameter estimation of the inverter-driven squirrel cage induction motor

When the inverter driven Induction motor is compared with sinusoidal voltage driving, the loss is increased and efficiency in the same output is decreased by the time harmonics in inverter output. These are based on the eddy current on stator and the skin effects of rotor bar current induced from time harmonic. The aim of this paper is to estimate the equivalent circuit parameter of squirrel cage induction motor fed from inverter considering this effects.
