Auger motor question

[Nukemall]

This auger motor very slow to start, just hums for ages then trips thermal cut out. Am assuming I need to replace capacitor.
Does this have two different capacitors on it, and can anyone point me in the direction of suitable replacement.
Thanks N.

Could be the windings also?

Capacitor UF is 100-13+20, doesn't hurt to go bigger especially on a well used motor. I'd google for a 150uf and see what turns up in the search

Here's a ( cough ) starting point

Here's a british supply.

Having said that it could be a sticking centrifugal switch inside the motor, and having two fitted it could be a cap start, cap run motor.Sticking TDA motor in to Google suggests it's cap start,cap run

Capacitor Start / Capacitor Run (TDA) single phase electric motors are able to handle ... that are too demanding for any other type of single phase electric motor.

You can test the caps with a multimeter if you have the uf function on it

I usually test them inadvertently with a thumb or finger

Thanks for the replies.

The picture is of my spare motor, that I have now swapped out. The sick one has a hole burnt in the larger of the two capacitors.

I have three identical motors, so could swap capacitors to check.

Does the uf rating on the motor plate apply to both capacitors, if so why are they different physical size?

 

[Fergieman]

The Capacitors are different ratings, one for starting and one for running. The numbers are usually stamped or printed on the capacitor, but looks like 130 and a 20 would suit.

Hole burnt in side of capacitor is a sure sign it is fecked.

Thanks all.

It could have a centrifugal switch in the end of the motor for the start capacitor, worth checking

If it's critical , a NEW motor can't be that expensive -- can it?

Most times at the cost of a repair no, labour costs are expensive, if it's simply a capacitor maybe worth repairing.
