here's 4 more schematics of magneciters The plain 04sx and 06sx are shown in a picture posted a while back on this thread.

Thanks to Leon, I was able to literally piece this document together.

This is Onan's explanation of the Magneciter, from the J Line brochure.

Maybe no surprises by now, but it's nice to see it all laid out in one go.

Most interesting point: They claim the Magneciter is " Five times faster than brushless type generators"

"Regulation is literally instantaneous since rated voltage is restored
within two seconds after being affected by a load change."

How does that compare to a modern AVR?

I stumbled across this little gem of an E-book while trying to find some basic info on magnetic amplifiers.

And a direct link to the .PDF

Here's another "take" (gleaned from Marine Training Manual #932-0405 supplied by Richard L. - Thanks Richard) on the same information. See Attached.

If you need any info on the magnacitor or how to upgrade as the reactors are not
available, I work in the field for Cummins PG ( Onan) and have developed a few kits for our customers who want to keep the old gems running... I would be glad to share... It would make Gene Tadson smile from above to see his design still in use. Kilowatt.

I'd love to take a look at what you have come up with.

I think some of us are learning the dark art of coil winding - just in case.

Isn't it funny how the magneciter isn't designed with fuses in the circuit ???

Default Re: Magneciter differences -06SX

Hello Ted:

Just happened to review the Magneciter FAQs. Very interesting. Re your question: Does anyone know when/where/why the different 06SX magneciters were used? I think I found the answer in the Onan JB Operators manual, # 967-320. See page 23 for the appropriate the parts key number. And on page 44, the note indicates the 06SX series was used on the 50 cycle plants.


Leon

Onan magniciters are not like the Caterpillar SRCR gen sets . The Cats require over 40 amps DC to the rotor through the brushes, and any problems with the brush and slip ring contact causes sparks that will eat up the slip rings . Or cause the regulator to blow one ,or all of its three fuses or go out altogether. It was not a good design when compared to the Onan Magniciters .
One reason was the Onan didn't use the high amp excitation like the Cat did. And if you cant get your magniciter to work. You can remove it all together ,and contact Paul Huber at Powertronics in Kerville Texas and buy a UVR500 voltage regulator for around $225.00 .
Couple it up to a SE350 module for around $ 35.00 . Then just run off your old brush holder a set of F1 & F2 wires to the SE350 Pos and Neg post . You can mount this rig inside your control panel because it is about the size of a pack of cigarettes .
I still know customers that let us do this, and are still running the older brush type Onan gen sets over 250KW on their Farms and Dairy's with no problems at all .
Cant say that about the Cat SRCR gen sets .
