(and indian company with no website as far as I know) , is it possible to keep the belt at a position and just put a VFD and use that to change the speed/torgue?

    Yes, but you need for that to work well - 4 pole 3 phase motor rated at ~1400rpm. Then you would be able to control it in the range of 600-3000. As you see is not enough. So you need DC motor, say from a thread mill, or even better would be a servo motor. Expensive? Then change belts...
