Dennis Parmley Posted April 14, 2023 Share Posted April 14, 2023 What is the best or safest voltage to run my C-frame Edison battery fan on. It seems to run fine on a 6 volt battery, but would greatly appreciate any input as what it should be run on. THANKS. Quote Link to comment Share on other sites More sharing options...

I use 6 VDC battery. 1 Quote Link to comment Share on other sites More sharing options...
Jim Kovar Posted April 14, 2023 Share Posted April 14, 2023 Originally,... four "S" cells in series. An "S" cells is ⅔ of a volt. Four "S" cells in series would be ⅔ x 4,...which is 2⅔ Volts. I know many collectorsrun their C-frames on6 volts and I don't thinkit's detrimental. Quote Link to comment Share on other sites More sharing options...

Curt Davis Posted April 14, 2023 Share Posted April 14, 2023 For later model C-frames with 12 sections on the armature they can definitely run just fine at ~2.8V (see first video below) which is in agreement with the excellent documentation provided by @Jim Kovar For the earliest C-frame's with only 6 sections on the armature I believe that 6V is needed, but I don't have any documentation to back it up, just an experimental observation (see second video below). 1 Quote Link to comment Share on other sites More sharing options...

Steve Stephens Posted April 14, 2023 Share Posted April 14, 2023 I have found that my later C-frame Edison likes 3-4 volts I think. I run on a variac to where it seems happy and not running too fast. Quote Link to comment Share on other sites More sharing options...
Jim Kovar Posted April 14, 2023 Share Posted April 14, 2023 (edited) I'd at least try the cheap and easy way first. An electro-geek would prob'ly have such a thing in his stash? I'd think a 3A rating would be enough? Most switching power supply wall-warts protect themself from over current (a shorts or heavy inrush currents) by shutting down.

George Durbin Posted April 16, 2023 Share Posted April 16, 2023 I use power supplies all the way up to 32v.dc... Great for odd dc voltages... I find nearly all of my dc power supplies at Good Will stores... dc measurements on the power supplies are in milliamps... So you need 1500 milliamps = 1.5 amps dc...
