Abstract

Load with severe torque fluctuations can be driven by an induction motor with control of input frequency using VVVF inverters. Situation of rise in load torque can be met by reduction in frequency at that instant. Situation of sudden reduction in load torque can be met by increase in frequency, at that instant. This paper deals with computations for such cases using the graphical relation between torque and speed, finally leading to a plot of instantaneous motor torque as a function of time.
