Lathe Reverse

[blackburn mark]

No joy....
Now it will run forward but not in reverse...…
This has me baffled.


It will run forward but not reverse with the Cap on pin2
It will run reverse but not forward with the Cap on pin4




This switching scheme rotates the removed bus bars through 90 degrees, is there a way I could cause damage by trying the cap on the other two pins?

Have you seen this vid https://www.youtube.com/watch?time_c...ature=emb_logo

I take it, it is a single phase motor with a capacitor

When your motor runs up to speed do you here a click and another when it slows down.

Hi Clive
Its single phase according to the plate and it has a single capacitor
I hear no click on the run-up or run-down

Its an old Clarke motor that yields very little when run through google :(

Do you know how it was wired originally. Watch the vid till the end

In its original wiring, it runs counter-clockwise as I face the shaft.... I can get it to run clockwise by rotating the bus bars through 90 degrees BUT I have to also move the Cap from pin2 to pin4 which seems odd and I don't have enough pins in the tumbler switch I have in order to implement that.
I was hoping an expert would reveal how dumb I was and say something like "you reverse it by moving the cap only"



I did, I don't know much about AC motor schemes but that motor looked (and sounded) like a different beast to mine.

That is my question now too.

I would expect all motor wires on 1 side actually... may my bad.

Do we agree on the schematic?

I would too but I'm assuming its been dropped onto that pin for lazy convenience // the fact that it uses bus bars tells me all those pins are isolated so one is as good as another :)
