Great Job!

Jon,

Your system for calculating speed matching is right on. If you want some more information (and reinforcement that your right on), look in the white papers section unde "Novi Kickoff". I put my preso from this year's kickoff in there. It specifically adresses the problem you worked through.

I agree with Andy that 90% is way too conservative. We use 97% and it matches our output tests pretty good. Also, try to get 3 or 4:1 reductions if you have the real estate; because, like Andy said, it will pay off.

I compliment you on your analysis. It is very well thought out.

One word of caution, when you are not operating at 30 (40) amps, the slower motor will act as a generator and not contribute much to the output torque. (When running at top speed) Do the mat and you will see what I mean.
