Re: [TCML] 3 phase mot dc coil first light



Thanks Ted, yet another thing I forgot to mention. The MOTs have their bottoms removed (open ended cores), so saturation should be pretty much impossible. Tonight I might try and pull three of them out of the oil and disconnect the cores. I'm dreading trying to sand the insulation off the HV wire though.

Well Greg looks really good. The machine will be interesting when configured 
for full power.

I was not too sure if you gapped your ring up inductors or not but I believe 
it is quite important if they will be running more than about 300mA . The 
cores saturate quite easily and gapping made a big difference.

In some less than well documented experiments I set up a MOT to measure the 
actual inductance as the DC component in the secondary was increased against 
various gapping from zero gap thru to about 0.5mm which is why I am sure 
gapping is the way to go and to array them up to get the inductance 
required. Thanks for the post

At low power, low coupling and limited tuning.... few gremlins to iron out 
though:
