![]() Thus, the dynamic model considers the instantaneous effects of varying voltages/currents, stator frequency and torque disturbance.Īssumptions and Definitions: Space mmf and flux waves are considered to be sinusoidally distributed, thereby neglecting the effect of teeth and slots. Thus, we need to evaluate dynamics of converter-fed variable-speed drives to assess the adequacy of the converter switches and the converters for a given motor and their interaction to determine the excursions of currents and torque in the converter and motor. ![]() they cannot supply large transient power. Variable-speed drives are converter-fed from finite sources, which unlike the utility supply, are limited by switch ratings and filter sizes, i.e. Such variations arise in applications involving variable-speed drives. 1 Modeling of Induction Motor using dq0 TransformationsĢ Introduction Steady state model developed in previous studies of induction motor neglects electrical transients due to load changes and stator frequency variations.
