Time Domain Steady-State Torque Calculation of Voltage Source Pulse-Width-Modulated Inverter Fed Induction Motors, Part I: Theoretical Analysis
Evaluation of torque pulsation associated with the harmonics of pulse width modulated (PWM) inverter-fed drives is important for a quiet and smooth operation. This paper discusses an analytical method for the steady state ...
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 ...
Monitoring of Defects in Induction Motors Through Air-Gap Torque Observation
This paper suggests a method to monitor defects such as cracked rotor bars and the shorted stator coils in induction motors. Air-gap torque can be calculated while the motor is running. No special down time for measurement ...
