Everyone,
I wanted to post a couple of things on coil wire size. in speaking with John we were discussing the 3pole Kit I sent him, he said "the wire is too small, coil to small, magnets wrong, rick is selling chargers not energizers" one is low cop the other is hi cop. the 3 pole kit is good for 1.2 amp hour batteries, that is all. the tiny window motor is not a window motor, it is an SG, and it will NOT charge hi capacity batteries in any decent amount of time, you just have a fancy whirling motor, that will light led's
23 and 26 wire will not work for larger batteries, the wire is too small. this is one reason why the 10 coil was such a pain to get decent charging from, the wire was too small at 23awg.
the minimum wire size on a bike wheel SG is 19 awg for the trigger, and a pair of 21awg in parallel for the power winding. 150 feet is a good start. litz the 3 wires together, then onto the spool. better is 18 awg power and 18 or 19 trigger. remember inductance is a function of turns so use the pittsfield spool you see everywhere, 3/4 inch core is the size i believe.
then use a 470 ohm resistor on the base, no bulb no potentiometer, until you know what you are doing. get the energizer running, see how it charges then change resistors. 120 milliamp current draw maximum to start with.
this is for lawn tractor batteries from napa. big bike wheel 20 magnets good scalar south between the norths.
Thanks JB
