An Approximate Model for Studying Harmonic Current Amplifications in Current- Source Inverter Fed Induction Motor
The nature of harmonic current amplification in current source inverter fed induction motors is studied through a six-pulse current source inverter. An approximate model consisting of the induction motor and the parallel ...
Steady State Performance of Reluctance Motors Under Combined Fundamental and Third Harmonic Excitation Part I: Theoretical Analysis
The steady-state performance of two prototype polyphase reluctance motors, grooved and segmental types, under combined fundamental and third-harmonic excitation was studied by using injected third-harmonic magnetomotive ...
Possible Errors in Measurement of Air-Gap Torque Pulsations of Induction Motors
Measurements based on the accurately obtained air gap flux data using either the search-coil or the Hall-effect approach are not error proof. This is because even the unbalanced leakage effects can be reduced to a minimal ...
Capacitor Effects on Induction Motors Fed by Quasi Rectangular Current Sources
Analytical and experimental studies of the capacitor effects on the steep rising and falling voltage spikes and the current harmonics in induction motors fed by quasi-rectangular current sources were conducted for the case ...
Measurement and Prediction of Brush Interface Temperature at Sliding Electrical Contacts
Binderless copper-graphite composite electrical brushes have been fabricated with a high-energy and high-rate pulse sintering technique. Experiments were conducted to measure the interface contact spot temperatures of ...
