GE ECM wireing mods.

[Jerry]

Hi Roger>

Here are a few pictures of the ECM and laithe testing at 500 rpm. In these pictures the alt is Jerry riged.

You will see the 36 wires. Its not that hard to make the 3 goupings. Then wire each phase to its own bridge. Or you can wire star or delta.

Sorry can't find the load test #s. I don't remember if the voltage showing on the Fluke is under load or not?

I think I was geting 30 watts around 10 mph and 380 watts at 30 mph. This out preforms the 403 and its quiet. I'm sure I would have seen over 500 watts in yesterdays wind storm or more?

jerry i have a 1/2 hp ecm moter . i tried to hook up in star by bringing out the internal connection. but the output stayed about the same .how about showing a diagram showing how you joined all those wires up .thanks in advance.

Hey Jerry,

I have your lathe test post in my hotlist here's the link:

One question, does the GE ECM have a ferrite magnet rotor?

If that's the case then the performance is awesome.

Jerry,

Cool, and I do have a handle on this now. That's exactly what I thought. I'm going to make up a diode array and try that first. I have a pile of big stud diodes and a big heat sink just waiting in the engine room, left over from a alternator experiment. Thanks ever so much!

I wish I had a bin of these "burned out" motors and a pallet of your blades!

Will post my results soon. And Yes these have ceramics on them now. I have a pile of hard drive neos I'm thinking of break forming into new poles for its rotor. It might take a real big difference or none or lessen output. One thing at a time. :-)

did you run out of yellow wire, when you were winding this?

the coil just above three o'clock and the one above it , about two o'clock , have the same white color wires?

[Jerry]

Thats a prety sharp eye you got there Willib. It sure looks that way. You can also see a couple wites grouped with the yellows in the laithe test.

Good thing the phases and electrons are color blind.

I'll load up a quik scetch of a schimatic for 1 phase coil gruoping.

And yep these things use ceramic magnets.

Here is a quik schimatic of the 6 coils of 1 phase wired in perelell. Treat this as 1 phase do the same to the other 2 phases and wire as per your preferance and capability of your blade and wind location.

I belive I wind tested this unit with Jerry Blades and Jerry rigged and saw 380 watts at 30 mph?
