"Topic: Pony motor speed question"
Bnesson made a link to some very interesting relationships about starting current versus armature speed. I want to thank him again. I read the whole site and my only dissatisfaction was that many of the terms in the equations were not defined, and as a mechanical engineer, their meaning was not self evident. This is not Mr. Nelsons fault. That information should be very useful for anyone building a converter with a starter motor.
I am interested in the same quality of information relating to optomizing capacitor sizing on a converter. Is any similar thing available that relates the sizing of the run and the power factor capacitors to the power removed from a converter at a given load? I am familiar with two similar rules of thumb (1,2,3 and 60/40) but I am curious about the math that is behind them.
Thank You,
John Gill
