The best article I've ever seen on reversing a motor.

By the dude who designed my band saw.

I had linked to that in my original reply which got lost somehow. That guy is a mine of information. I lost a couple of hours to him the other night. I'm a bit too addled at the moment to follow everything he is saying and my motor seems atypical.

Why not use the belt in a figure eight configuration?

Can't take credit for the idea.

It looks very easy on the drawing, less so IRL

BigV · 11-17-2016, 03:00 PM

Can you skew the mounting of the motor at all to give you a little breathing room as the belt crosses itself?

What about a different belt?

Not your regular powertwist v belt, maybe round in cross section, a rubberized rope, tarred rope.... Thinking out loud here.

This is a temp solution to get you turning for this weekend's work/sales. You can get the motor rewired at your leisure later.. Or, things are different IRL.

There is literally no room for any solution apart from a CW running motor.

Last night I figured since the first motor was more or less fucked I decided to screw with it and see if I could get it working again. apparently I put something where it wasn't supposed to be and when I plugged it in there was an impressive arc, shower of sparks, and popped breaker. It's now in the copper recycling outbox.

Still waiting on my electrician friend. In the meantime I have some other paying work to attend to and I'm also scoping Craigslist. Saw a great (most likely stolen) Baldor 3 phase, 3HP motor for $100, new in box, only about 40 min away, and another new in box, single phase 1/3 hp motor for $50, but it's about 2 hours away.

They keep popping up on CL and I can also make a trip to the recycling place and pull another one out of a fridge there.

Here are some pics of the sewing machine motor, as you can see it doesn't even bear a passing resemblance to the drawing on the rod building site.

What are you going to do with a 3 phase motor? Surely you don't have access to that kind of power supply in your house. Way more trouble than it's work.

footfootfoot · 11-17-2016, 07:59 PM

Of course not, again, I'm not being clear because I'm addled. I meant I saw it it while looking for motors and was attracted to the price and quality until I saw it was three phase, etc.

glatt · 11-17-2016, 08:04 PM

Ah, yes. I've fallen for the same trap numerous times. You see a wonderful motor and get all excited only to notice a few minutes later that it's 3 phase.

xoxoxoBruce · 11-17-2016, 08:08 PM

There is an add-on box to change single phase into three phase, but it's bullshit you don't want to get into.
Guess I'll have to look at my whole shelf of motors tomorrow.

Gravdigr · 11-18-2016, 01:20 PM

I just broke a tooth, clenching my jaw.

God dammit.

BigV · 11-18-2016, 01:53 PM

Owwwowowwuch!

glatt · 11-18-2016, 02:51 PM

I guess that explains the banging your head against the wall icon in the day in history thread.

Seems like you could use some relaxin.

A shelf of motors? I am envy.
