An induction machine model including interbar currents for studying performances during transients and steady state

摘要: Abstract This paper presents a mathematical model of three-phase induction motor taking into consideration the interbar contacts. Several models have been available in references. However, they consider rotor as being constituted either or squirrel cage even if it operates under stator and/or faults condition. Nonetheless, contact between bar and iron core for machine has to be considered, especially when fault occurs. It is obvious that currents are influence constitution materials. So, aim’s concerns transient motors which can broken bars defect. Despite its increasing complexity, could able provide with useful indications diagnostic purposes. advocated simulation behavior defect takes account currents. The proposed technique based on mesh analysis cage. As low power prevalent industrial plants, we pay special attention them. Notwithstanding, additional due non-insulated constituting core. monitoring predominantly made through current at nominal Moreover, this one observed steady state operating system, knowing generally fed by sinusoidal supply. Consequently, results showed prove effectiveness approach, impact resistance both line spectrum diagnostic. An experimental test proves model.
