Hi we have a air compressor with a large electric motor 240 V 13 amp single phase 2 hp 1430 rpm and are in need of a replacement start capacitor wondering if anybody can help with Size and type. Any help would be appreciated, thanks.

 

I would start with at least a 20μf to 40μf motor start rated.
If you obtained a couple of 20μf you could test using single, parallel, series combo to get in the ball park, if it is a start capacitor, it is only in circuit for a few seconds just to initiate rotation.
Are you sure it is just start cap type, or start/run type? i.e. in circuit all the time.

No capacitor values unfortunately.

Good advice from Max.

Good luck, twohats..

Thank you for your help will try this today. The starting bindings on this motor are controlled by a mechanical centrifugal switch unit so all should be good with running start capacitor type thank you again.
