Replacement Motor Wiring

[Gary LynchParticipant @garylynch39491]

HI Everyone
Seasons Greetings etc.

I am currently fixing my Clarke CL430 after a motor meltdown 🙁
I have bought a new motor from TEC but I need some help with the wiring.

The CL430 has wiring for 4 poles Live, Neutral, and 2 Black ones for the Fwd/Rev switch
Here it is

Here is what I’m seeing in the new motor

Black Wire at Z1 and Red wire to left is the capacitor

Now I’m not going to pretend I know what to do here so that’s what I have come to ask 🙂

What goes where?
Here is the book diagram

Here is what’s under the lid

I’m assuming that the
Live goes to U1
Neutral goes to U2

But I don’t know where the 2 Black wires for Fwd/Rev go 🙁

Thanks
Gary

It depends on what the F/R switch does. I suspect it is a double pole changeover switch. In one position it connects one black wire to live and the other to neutral. In the other position it swaps them over so that the first black wire is now connected to neutral and the second to live.

If this is a correct supposition, then (AFTER TAKING OFF THE LINKS) one black wire goes to Z2 and the other to V1. The F/R switch in effect replaces the links shown in the new motor diagram.

If the switch is in one position live is being fed to U2 & Z2 while neutral is connected to V1 & U1 and the motor will run clockwise. In the other position live is being connected U2 & V1 and neutral to U1 & Z2 and the motor will run counter clockwise.

Check very carefully using a meter that my assumptions/suspicions are correct. If not then the original motor is of different design to the new one and you will have to do some work to connect it up to the F/R switch.

U1 and U2 are the run windings Z1 and Z2 are the start windings. Your motor from what can be seen is a capacitor start, induction run, NOT cap start Cap run. To reverse rotation swap Z1 and Z2 but leave U1 and U2 as was. How this is done will depend on the reversing switch you have. One convention was U1 red, U2 black, Z1 yellow and Z2 blue. Using your meter you should be able to sort it out. Good Luck and Happy Christmas. Noel.
