Hi Warrjon

Thanks

Just to Clarify, is this what you mean (see pic)

Also when I test Z1 & Z2 do I put one lead from the meter on Z1 and the other lead from the meter on Z2

and the the same with U1 & U2

 

Yes correct for all

 

OB one thing I forgot to mention - U1 and U2 are one winding and Z1 and Z2 are the second winding.

You will need to disconnect one end of each winding when you meter them.

 

Hi Warrjon

Can't wait to try it out and see if it works, I didn't know it was possible to reverse a motor like that, which shows how little I know about these things.

 

Hi Warrjon

Swapped the Wires but it still spins the same way as per the Arrow I marked on the case.

 

Put it back to the way it was Z1 back to U2 and blue capacitor back to blue 240V...... My fault when I redrew the circuit I transposed the coils.

 

Hi Warrjon

Cheers, I will give that a try.

 

Have you verified that you can't just use the motor as it is with the hydraulic motor. A lot of hydraulic motors are bi directional.

 

Hi Hitch

No I haven't done yet but I'd rather try and reverse it if that's possible but I have been so busy today, that I haven't had time to try and re-wire it.

 

Hitch, I know sod all about hydraulic pumps, and from the photo of the pump casting OB posted, it did look like the inlet and outlet parts of the casting were to same. BUT unless we can be sure the pump is bi-directional, OB, I would not want to be underneath anything it is holding up!

Hi Greg

Whenever I've lifted the Car up, I've always had Safety Props underneath just in Case but the fittings on the Side of the Pump don't look interchangeable from what I can see and in the event that were the case, I've heard you can mess all up the seals.

So I'll wire it up and see if it works and if it doesn't run Anti Clockwise, then I can always use it on a bigger Compressor and buy a complete hydraulic unit to go on the lifter.

 

Hi Warrjon (aka 'The Wizard of Watts')

I wired the Electric Motor just the way you said and its now running 'Anti Clockwise' just the way I wanted and I couldn't be more pleased.

So Thank You Again

For Your Help.


It looked like a piece of Scrap
but not anymore!

 

Great Al, now lest see this lift in use.........

 

Hi Warrjon

One more little problem to be overcome!

The other Motor Had a Thinner Shaft and this ones 20mm.

So the Fitting off the Old Motor will be too Small to go on the Shaft, so I could either drill a bigger hole through the Fitting or find someone with a Lathe to bore it out.

I think the fitting also has a Key Way, just to make things a bit more Complicated.

When I get the fitting off the Old Motor, I'll put up some pics and hopefully find a Solution.

Thanks Again!

Hope you enjoyed the Movie!

For reasons that cannot be explained, the Motor runs even smoother Anti Clockwise.

 

OB / Warren,

Sorry Guys, did I miss something in the posts here? If the wiring is back the way it was originally, how has the motor become reversed?

Tks

Hi Paul

The Fix came via email on a diagram to die for and now that little Motor is Spinning like a dream!

 

Perhaps you'd like to share just in case some other poor soul has the same problem?

 

Electrics and then electronics. In my limited lexicon, related. But the former less complex than the latter. I mess with the former fairly well, the latter, not nearly so much.


A couple of years ago, my son gave me a little old Atlas Lathe. Partly in pieces and one critical one missing. A successor company could furnish anything but the missing one. The pattern was lost.


I found one on Ebay. Hooray.


I had a nice little 1/3 HP 120v AC motor. Ugh, Wrong rotation.
As it would drive the jack shaft via a V belt, I could have swapped it 180 degrees. But, not a clean look and take up needed space on my bench.


Two other solutions came up.


A. Reverse the rotation. A visit to a friendly electric motor shop taught me how. And, they had the Vbelt in the size I needed.
The little Atlas purrs. Only the three dog chuck challenges me.
But, it has made swarf....


B. EBay again. Reversing switch. I bought one and got four. I decided to use one as an on/off as they were high quality. Sold one on CL.
Have two left.


That sure is a hefty saw. I would be tempted to fix it. I'd name that thing "tiger". Wicked blade...

More:


The left over bench. Decades ago, I got one at a yard sale. Similar
in size, etc. I made it in to a dual use piece. At another sale I got the power head of a radial saw. In great condition, but the ways were
stuck!!


I added some strap steel by welding to strengthen it and then bolted
on two striking surfaces. One a chunk of big I beam. The power head clamps to it. I installed a big wire wheel. Brush big old rusty stuff. I did a lot on it on a past project. Clamp on little vice to hold small pieces for welding. A flat for pounding metal. Done a bit of that.
It also has four holes bored in the corners. Bolt work down when needed.


The other part, a chunk of RR track cut to resemble a black smith's
anvil. Big hammer use here.


The thing is on casters, now. the lower part houses the power head when not in use a nd a bunch of clamps and the little vice.


I term it my "bash bench".

Hi Norri

That probably wouldn't be a good idea, as I doubt if all Electric Motors have a Wiring layout that is exactly the same.
