A motor Start Cap
is used to briefly shift phase on a start winding in a single phase electric motor to create an increase in torque. Most electric motor start capacitor applications use a rating of 50-1200 uf capacitance and voltages of 110/125, 165, 220/250 and 330 VAC.Round Start Cap, 110/125V, ¼" Flag Terminal, 50/60 Hz

Is it time to replace your Electric Motor's Start Cap?
Depending on the frequency of starting of a piece of machinery, the relative load during start-up and the temperature of environment that it is operated in, every motor's start capacitor will eventually have to be replaced.
How do I know if my Electric Motor’s Start Cap is bad?
Most electric motor start capacitor failures are one of two types:
"The Start Cap blew its guts out!" This is what we call catastrophic failure. It is usually caused by an electric motor's starting circuit being engaged too long for the intermittent duty rating of a start cap. The top of the start cap has literally been blown off, and the insides have been partially or fully ejected. Similarly but not quite as dramatic, a start cap may just exhibit a ruptured pressure relief blister. In either case, it’s easy to tell that the start cap is in need of replacement.
"My motor is slow to start. Is my start cap bad?" The answer to this question is maybe. Your start cap may have lost its capacitance rating due to wear and age, or you may have other non capacitor related issues related to other motor components.

"My experience with TEMCo was very smooth...
The shipping was very reasonable, and the liftgate charge was surprisingly low compared to what is usually charged. Another nice perk was that my order was upgraded to the next size for no additional charge.
I am extremely pleased with ... my purchasing experience as a whole. Do yourself a favor, and consider one of the TEMCo converters; you won't be sorry."
Dave Moore, Precision Machine Service - Huachuca City, AZ 
"Excellent advice, service & product. The staff helped determine exactly the size converter I needed, answered any questions I had thoroughly. The unit was shipped quickly & was very welled packed. The product is so well designed that installation was a breeze & the converter works great. Got me up and running very quickly."
Michael Hall
"You guys were referred by our electrician as well as our local light/electric company. Very friendly, very knowledgable."
