As a step toward the self-commissioning of the next generation of ac drives, this work deals
with an automatic procedure for the identification of the inverse-Γ equivalent circuit of …

Heating and losses of induction motor (IM) grow with the supply voltage unbalance and
harmonic distortion. To avoid thermal overload, the IEEE 141-1993, the IEEE 3004.8, NEMA …

This paper aims to complement studies concerning the influence of voltage unbalance on
the performance of induction motors. We use sequence equivalent circuits to determine the …

Effects of voltage unbalance on the induction motors power, torque and vibrations are
analyzed in this paper. Voltage unbalance produces power oscillations at twice the supply …

This paper proposes a novel algorithm for the parameter identification of induction motors
based on third-order generalized integrators (TOGIs), where both the electrical and …

In low voltage induction motors, the first indication of a stator fault is the appearance of an
interturn short circuit. For this reason, several attempts to diagnose reliably these short …

O objectivo primordial deste trabalho é o de propor um novo método de diagnóstico de
avarias nos enrolamentos estatóricos de motores de indução trifásicos, quando estes são …

In this paper we estimate the effect of voltage unbalance on the losses in the core of the
induction motor (IM). To measure losses in the core of the stator and the rotor, we used an IM …

Three-phase induction motors are critical devices in many engineering areas including high-
speed train, aerospace, electric vehicles, industrial robots, machine tools, etc. Nowadays …

This paper proposes a novel method for parameter identification of the induction machines
(IMs) fed by PWM inverters at standstill. Two different AC voltages (1.2 V/200 Hz and 0.7 …
