While the development is progressing, we have been able to get a sponsorship from a local company with some AC motor drive systems coming on the market: Rinehart Motion Systems at www.rinehartmotion.com

The motor is in their hands now for setting up the inverter and confirming by testing. We will then make a simple adaptor to attach it to the mount system already in place for the 200kW drive unit.


Things are looking up

Things are looking up for the inverter SW design. There are multiple design efforts now going in parallel with this very capable power stage hardware.

This is one of those things that we did not plan to spend time engineering, but some times you have to take matters into you own hands… On the bright side, this forces us to thoroughly understand the optimization parameters of this critical element of the drive system that will certainly have big payback on future projects.

This 200kW Inverter has not been completed and the Dutch company Evisol has run out of money while debugging their SW/HW problems.

The new investors have personally pledged to repay or deliver after new development restart but is just words rather than any guarantee.

At this point, those of us that invested in this product don’t expect that they will deliver anything that will make our Inverter hardware functional. The company name has changed to ??? and we would be skeptical of … stay tuned …

Original Plan : …. delayed for redesign of the DSP board
