Lathe Motor Capacitor

You got it, motor shop or internet. Should be start on a 1/2 horse.

Match capacitance / voltage.

Mike,

I suspect it is a run capacitor. A starting capacitor is switched out of the circuit once the motor reaches a predetermined speed. This is accomplished by a centrifugal switch. Often you can hear a click from the switch when the motor speeds up. Generally it is easier to hear the switch close when the motor is turned off and is slowing down.

If this cannot be heard it is fairly safe to assume the capacitor is in the circuit all the time. (This is probably cheaper to manufacture since it eliminates the centrifugal switch.)

Just match the value, 25 uF and rating, 250WVAC and you should be good to go. You should be able to find it at a industrial supply house that handles electrical items.

Hope this helps,

Harry

I would sure look somewhere else. I need bearings for my Jet mini, and Jet quoted me $38 bucks plus shipping for them. I would have been looking at something just under $46 for more Chinese bearings.

Got a quote from a local bearing shop for Timken bearings - $20 for both.

I am thinking that Jet is trying to make a little extra kick on the "genuine Jet" Chinese parts line.

Go to a motor repair/rewinder/parts store and they will have what you need.

Lathe seems a poor choice for a permanent split capacitor motor, but realizing that he wrote 25 microfarads makes it likely. Wouldn't provide a lot of starting torque at all. As a run capacitor, it'll be more expensive. Read the question, George.

I had this issue on my bandsaw. Took the capacitor off a motor I picked up for $1 at a garage sale and everything has worked fine for four months now. Brad

Mike.. how old is the mini?

I had the motor and switch/capacitor changed on mine under warranty... I've heard that they had a problem with motors for a while in 05... Mac

I think you got your money's worth, then.. *g*

Might be like taking a hamster to the vet... they tell you to just get a new one.. I paid $225 for my mini and if the motor hadn't been covered by the warranty, I'd of just bought a new one before I paid them over $130 for a new one...
