A short update, thanks to your help the engine is working, wired to the converter.

It's so silent! I even didn't know it was running...

Found a wooden case in the garage that should perfectly adapt to the motorized mill build. Since now it's full of things, I have just to convert it night time, when my wife is sleeping... :tank:

It does run quietly, once the mill is crushing its gets a little louder, but not much. Looks good!

This weekend I had enough free time to finish the build, some pics to show what I did

Probably in the next future I'll make some fine tuning, but first I have to use it a few times.

Thanks a lot to copbrew for his great help, this couldn't be done without him!!!

cheers

Really looks great, let me know how the crush goes. I adjusted mine down to .035 on the gap setting and wet milled the second time I used it. That along with batch sparging for the first time got my efficiency up 11%. Good luck.

The controllers you guys have are known as variable frequency drives or
vfd's. They will take your single phase and convert it to three phase, and give you variable speed control to boot. It varies the speed by varying the frequency (Hz). Your motor is great because it is made as inverter duty and variable speed. You are right that your motor runs at 170 rpm at the rated frequency of 60hz. But look at the spec sheet and that motor will run from 18 to 229 rpms at a frequency range of 10 to 90 Hz. Your controllers are also programmable, meaning you can set the upper frequency range above 60. If you set the upper frequency range to 90, your motor rpm will then be able to go up to 229 rpm's. Just letting you know in case you need the extra rpm's.

Thanks, I saw something like that on the motor info, and the VFD can be programmed to run higher, but I haven't needed to run higher rpm's due to getting a really nice crush as is. I appreciate the heads up though.

You guys made my day. Already had a bodine, and was trying to figure out the couplings. The links in this thread right to the l bracket and applied.com had everything I needed. Cheers!
