Contronics is offering its CoMoCo (Contronics Motor Controller) through their on-line site for 699 Euro. If you have an induction motor this is a great way to evaluate what InstaSPIN-FOC can do for your product.
This is the product -thanks to the InstaSPIN-FOC PowerWarp mode - that during a 14 month field trial saved over 80% of electricty vs. single phase triac control and about 50% savings vs. standard FOC. You can watch a video overview here.
