DougThis is how I have connected the Samsung motor to the 2.6 KW generator.Now I must drive that Samsung at 3600 rpm, using up to 400 volts of pulsed DCGetting 400 volts DC is no problem
Getting it pulsed, and sequenced, is the issue, along with applying it at the precise moment in time.I have an Arduino board, and am building a circuit designed by Thomas Buie.It is published by Patrick Kelly in the latest version of his on line book chapter 32.The circuit requires feed back from the coils to sense position.However, there is a problem.EMF, our old problem buddy can shoot back into the controller, and kill the brains,A schottky diode might protect the gate drivers, but then squelch the position signal. Hmmmmm?
Ideas? ( Doug. I love your mechanical solution, but this sucker is way up in RF frequencies)Cheers Warren
