Hughes" To: "Rotary motors in aircraft" Ernest, What is the other box upstream of the large heat sink? I assumed it was a controller / regulator. Looks like it goes in the dash / panel. Also they make several current ranges. (Can't find them on the new site) But I know I read about a 22A and 32A unit in the past. Not sure if it is possible on the shaft but John did say they where stackable on the water pump unit. Would that require two belts?

In the bottom of the picture on the right. That is the regulator. It works by dumping excess energy to ground. It looks like a heat sink, because it IS a heat sink. If that thing burns out and you rev high enough that the rest of your system can burn off what the generator puts out, you're in an overvoltage situation. The specs claim 1/3rd Hp to drive it. That is about 18A at 13.5V. I'll make a big assumption here and assume that they rated that at 5500RPM, the same number they used to compare the pump flows at the bottom of the spec page. Using this on the end of the crankshaft would be a simple matter of bolting the coil pack to the front housing and the bolting the 'can' that carries the magnets to the end of the shaft. Many motorcycles use this exact same setup, and you can buy some of those packages for about $100. I looked at and rejected those, because 18A isn't enough for a replacement; though it will do as a backup. Harley Davidson makes a similar setup for their Goldwing bikes that is 35A. That is the one I want to look at. >> Homepage: http://www.flyrotary.com/ >> Archive: http://lancaironline.net/lists/flyrotary/List.html
