Can I reverse this motor?

Can I reverse this?

 

[winchman]

From memory yes, I am sure a proper leccy will be along soon

 

[daleyd]

Is that a 3 phase motor wired with a cap for single phase operation?

 

[daleyd]

No, it's single phase from the start.

Yep, right enough I couldn’t make out all the winding wires earlier as I was on my phone, I wasn’t sure as it’s a 3 phase terminal block.

Some motors have a picture on the inside of the cover showing the connections needed for different directions of rotation

 

[carbon]

Most of the single phase motors I see have a six post terminal block

Permanent capacitor single phase?

6 post blocks are used on most these days, easy to source and easy to set up for switching direction.

Yes I thought as much, but I’ve wired about 2 single phase motors and hundreds (probably thousands...) of 3 phase. To say my single phase experience is limited is an understatement

 

[dannyp]

swap the wires over on one of the windings

Here, wire it this way and you'll only need to switch the jumper positions to reverse...

Colours annotated are only for this motor...

If it's required to be switchable, that's fairly easy so anyone can just ask.

What’s going on Pdg???
Mix of capital and little letters, missing dots on i’s and two corrections made (white and direction). Tut tut.
Only kidding mate. Couldn’t resist.

I was up until stupid o'clock wrapping (which is now unwrapped)

I have a cold (well, the wife says it's a cold, I'm quite sure it's a mix of an aneurism, influenza and ebola or similar)

There's probably other things too

Wine and beer Pdg. Always blame the booze whether it’s true or not. It’s the best Christmas excuse there is

 

[RichardM]

I have a cold

probably man flu - women don't understand it - you need time to yourself and whisky

 

[Brad93]

Yes, you can.

If you can furnish me with where all the wires were originally connected (specifically, the incoming neutral and the right hand white wire going into the motor) then I'll draw you a crappy picture

My dad thought changing the live and neutral would reverse it

 

[Brad93]

Thanks for you diagrams PDG I’ve sent them over to him. I’ll let you know how he gets on

 

[Brad93]

No probs.

Wire it like that and it'll turn one way with the jumpers one way, and the other will switch it

I didn't label "fwd" and "reverse" because those terms are only relevant once it's driving something, and because without knowing which way it's wound there's no way to tell until it's powered anyway.

Is it a one time change of direction or is he likely to want to keep swapping?

One time. He thinks a hydraulic pump powered by this motor has been setup wrong and is turning the wrong way.
He is gonna reverse the motor to see if the pressure increases.

He hasn’t had a Chance to try yet will update when he has a go
