Bit more than that. Like 2-2.5x scrap price.

I was wondering where you were going heading South towards Honeoye yesterday.. you passed our convoy when we were headed to the barn.

both motors on the mill run well, but pop the breakers after running for a while. And pop quickly subsequently, so it's like they need cooldown time.

I wonder if I somehow have my phases mis-identified and I'm backfeeding something?

phase-o-matic is labeled A-B-C and I've treated that as 1-2-3.
Guess I need to do some wiring research?


yall have any tips? maybe on identifying a mis-wiring? I do absolutely definitely have everything wired for 208/240 low voltage not 440 high voltage. one of these motors WAS test run after lead change so should assuredly be good. The other was short a support bearing to be test run after wiring.

Motor is to run on 208 or 240v?

My electrician friend told me a bit while ago that 208v motor *can* run on 240v but its not recommended. Motor will run hot and shorten lifespan

phase dont really matter, switch any two and it changes the motor direction.

208/220/230/240 meh same in house voltage, you probably have 218-225v at your termination anyway.


get a clamp meter and see whats pulling where.  maybe your breaker is crap or something is undersized.

Just re-verified wiring is consistent

I’m running no transformers, just rotary phase converter. Haven’t measured wall voltage.
My idler motor does not have a data plate.
Both mill motors marked as 220/440.
Lathe motor older than dirt and has no data plate.

Disconnects that are popping are identical for both mill motors and are this. I think this was running on 220 at the brewery, but I don’t remember for certain

No amps on b/2 which is the phase converter’s created leg.

Voltages are 200/210/235 between the legs.

The light on the phase converter acts as it did before I blew the capacitor and resistor. The motors work and sound right which they did not before I replaced the blown parts.

I guess I’ll check my wiring at the reverser switch and at the motors to see if I have an open on green and they’re running on 2 legs

i meant amperage readings to learn something.  a clamp on amp meter.  AC ones are common, mine goes to 600amps DC too :)

Finished drilling a hole on the mill. Ran for 2ish minutes before shutdown.
Zero power going from idler motor on the dead leg. Confirmed wiring from switch to disconnect.

Swapped 2 wires to reverse crossfeed motor, now it works as it should - but also still draws nothing on the dead leg and also pops its disconnect breaker.

I don’t understand how I have no draw on one leg with the idler motor going. Even if I did something wrong in fixing the phase converter, the idler should be doing its thing. It has no current on the dead leg at all.

I haven’t checked that leg with my lathe running.

I also haven’t tried pulling out the idler motor and going to just static converter.

Hrmph.

reread the phase-o-matic documentation and saw it indicated to put a SPST in the B wire if using an idler motor. I just did that, and symptoms did not change.

I didn't have a good angle to get the clamp around the B wire, but I expect it still has no draw, and that the differential draw is what's popping the 3ph breaker.
