Thread: Need help finding a capacitor for my lathe motor

Hey guys my lathe recently died on me while machining it has done this before were it would slow down then stop but all i would do was just turn it off then on again and it would work fine all though this time nothing happens not a sound or anything. I took the capacitor out, but some of the info on it has rubbed off and don't have much of a clue what im really looking at hahaha :/ So would some one be able to point me in the right direction i also added a picture of the capacitor. (only assuming that its the capacitor.)

The capacitor has all the information on it you need, the values shown are pretty standard. K.D. Fisher in St Marys, or anybody else that sells capacitors, should be able to help you out. They're only about $20, or $10-$12 bucks on line. You didn't mention how many capacitors the motor has.

You are looking for a 16µF (micro farad, sometime written as "MF" or "uF") motor capacitor for 380 or better still 450VAC. The rest of the lettering is not that critical.

If you turn it on and spin it by hand for a couple of turns does it eventually get up to full speed?

If it does keep spinning then it is definitely the "start" capacitor, if not then it may or may not be the "run" capacitor.

The capacitor in the picture is a motor running 16 microfarad (mfd) 450 V jobbie by the look of it.

These are a common motor capacitor just do a search on the web or flea bay

I guess you don't need me to tell you to be careful.

Ahk cheers guys i got really confused when i saw the 315v and 450v ahahah :/ the motor only has the one capacitor.

a air con place should have it

Big difference in prices, who's trying to rip who off ?? Australia the most expensive country in the world.

could be capacitor? but could also be something else.

I can test capacitor for you, what area are you in?...without looking in the odds n sods bin, may also have 1 if yours is crook

That old cap was made by Ducati, the motorbike company.

Jordan

Ahhhh, made in Italy.

That explains a lot.

Your lucky it went this long.

What Jhovel said....

Also, you will also probably be able to find a suitable replacement from Radiospares and/or Element 14 ( formerly Farrnell ) Thats where I get mine from. Best not to skimp on Capacitors as they work hard and I don't trust the chinese ones....
Capacitance is not critical, just something relatively close will do and as long as the voltage rating is as high or higher, would suit.
Buy two and you will have a spare.....

K.D Fisher are otherwise known as Plessey Capacitors. Plessey have been around for years.

I think the Romans might have a bit to say about that.

well i ended up buying this 16uF Multi Purpose NEW RUN Capacitor Suit 240V Motors | eBay should come by Friday, didn't want to wait a couple of weeks for one to come from china but ill be bidding on this motor Vintage Electric Motor | eBay just in case but if it works ill just use the one ill buy on the drill press since it needs a new motor Ill let you guys know if all is well!

check the rpm may be the wrong one usually 1440 or 2850 rpm drill press maybe different from lathe
