A low cost PC-based user interactive induction motor drive system

A novel low-cost personal computer-based (PC-based) induction motor drive system featuring real-time control of space vector modulated (SVM) waveforms, on-line motor speed and current measurement, and live innovative mimic displays of basic drive operations has been developed for teaching and training purposes. Front-ended by the ubiquitous PCs, the proposed drive system represents a fresh departure from the machine drive system in a conventional teaching laboratory in terms of its user-friendliness, user-interactiveness, and automatic data acquisition. Selected experimental results highlighting the salient features of the system are presented.
