In this paper an accurate loss model-based controller to calculate the optimal air gap flux is proposed. The model includes copper losses, iron losses, harmonic losses, friction and windage losses, and stray losses. These losses are represented as a function of the air gap flux. By using the calculated optimal air gap flux compared with rated flux for speed sensorless indirect vector controlled induction...
A comprehensive analysis of motor health may be accomplished by combining online and offline test results into fault zones. These fault zones are Power Quality, Power Circuit, Stator, Insulation, Rotor, and Air Gap. Power Quality focuses on the quality of the voltage and current. Power Circuit focuses on the power circuit supplying power to the motor. The Stator Fault Zone focuses on the turn-to-...
