An innovative DSP-based teaching module for electrical machinedrives

An innovative digital signal processor (DSP)-based induction motor drive system featuring real-time generation of space vector modulated (SVM) waveforms, on-line speed and current acquisitions, programmable soft-start, dynamic braking, and live animation on the basics of drive operations has been developed for teaching and training purposes. Front-ended by the ubiquitous PC that hosts a TMS320C30 module board, the proposed drive system represents a fresh departure from a typical machine drive in a conventional teaching laboratory in terms of its high user-interactivity, flexibility, and fully digitized approach. It has been shown that students using this system can devote their time to fruitful discussions and in-depth experimentations rather than repetitive manual measurements of the motor's voltage and current reminiscent of typical machine laboratory procedures. Selected experimental results highlighting the salient features of the system are presented
