Clarke CL430M Lathe Single Phase Motor Wire Layout

[David McNamara 1Participant @davidmcnamara1]

Hello,

I have a Clarke CL430M and I mindlessly unplugged the wires at one point while trying to dissassemble it to transport it but didn't record what the original layout was.

I have pictures:

Where the wires plug in:

The wires:

The instructions:

So as you can see what it says in the manual is not true, there is no letters E, N or L marked. And there are also two other black wires it doesn't account for.

Could anyone tell me into which holes the respective wires are supposed to go into or give a picture of the layout on the same motor?

Thank you in advance for any help.

Regards,

David

Does the operators manual not include a wiring diagram?

The CL430 is the lathe, the CL500M is the combined lathe and mill, but the Operator Manual and the Parts List covers both machines.

The Parts List contains the wiring diagram, (Page 2  ) so you should be able to trace which wire comes from which terminal of the switch box..

The motor connections are identified, (Visible in your picture ) so having traced which wire is which, it should be possible to connect the wires correctly to the motor.

Your right, the correct name is CL 430. I have looked at all the diagrams I could find online. I couldn't work out how they corresponded with what is in front of me. There are four holes, labelled D1 (K1), D2 , D3(K2), D4. I couldn't see these labels mentioned in any of the charts. I couldn't even recognize the structure of the charts I could find. I definitely wouldn't be able to arrange the wires with any confidence based on them.

If anyone is able to interpret any of these charts I would be grateful for any insight.

Regards,

Jack

Best to put your pictures in an Album, it's easier for people to view all in the same place.

If you look in the Parts and Wiring Diagram (Google if you don't have hard copy ) Page 2 shows the wiring diagram. This shows the connections on the motor, which are visible in your picture, and the terminals on the switch box to which they should connect. )

You will find it listed as "cl430-500m_tech" if you search for Clarke CL430 and 500M Parts List and Wiring Diagrams.

The mains feeds are listed as X1 and X2, each of which appear to connect to three contacts in the switchbox

X0 is presumably the earth terminal in the mains plug.

You need to study the wiring diagram and trace the wires with a multimeter back to the terminals in the switch box which should allow you to connect the wires to the correct terminals and get the machine going.

It is actually pretty simple if you do that.

+1. With a bit of luck it may not be necessary to use a multimeter.

The disconnected wires connect the motor to the 3-way switch shown on page 2.

Jack/David's image shows the motor connections are labelled:

D4 | D3 K2

______________

K1 D1 | D2

Have a look at the switch : hopefully the wires are labelled at that end too, and it will be possible to identify immediately which is which.

If not, by convention the Green/Yellow striped wire is Earth, so it probably connects to the motor frame at the centre of the oval hole punched in the gasket, bottom of photo. Again by convention Brown is Line and Blue is Neutral, so these probably connect to the motor's Run Winding. Thus the two black wires probably connect to the motor's Start Winding.

The Start and Run Windings can be identified with a multimeter measuring Resistance on a low Ohms range. The Start Winding has a higher resistance than the run winding, so the black wires are connected to the higher resistance terminals. If the black wires are connected the wrong way round, the motor will run in reverse when switched to forward and vice versa. Just swap them over. Getting blue and brown the wrong way round shouldn't matter.

Hint: when dismantling equipment take plenty of photographs and/or notes!

I arranged the wires like this and it seems to be spinning now. If you see anything wrong with this layout then you could tell me but it is spinning now (clockwise). Thanks for your help.
