TEMCo Heavy Duty Starting Capacitor for Single Phase Motor Applications
Get Factory level pricing! Most models of Start Cap stocked for Same Day Shipment.
Single phase electric motors use a device called a starting capacitor to create a large phase shift to produce necessary torque during start up. Single phase motors will commonly have both a run capacitor and a starting capacitor. Starting capacitors differ from run capacitors by their relative capacitance value being much higher for a given physical size. The starting capacitor will usually be identified as having a black phenolic or plastic case and a recessed top where the connections are located.
As a byproduct of high capacity, they are only intermittent rated and can only be energized for a few seconds at a time. For this reason, a starting capacitor is usually one of the first components to fail on single phase electric motors.

Is it time to replace your Electric Motor’s Starting Capacitor?
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, all every motor's starting capacitor will eventually have to be replaced.
How do I know if my Electric Motor's Starting Capacitor is bad?
Most electric motor starting capacitor failures are one of two types:
"The Starting Capacitor 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 starting capacitor. The top of the starting capacitor has literally been blown off, and the insides have been partially or fully ejected. Similarly but not quite as dramatic, a starting capacitor may just exhibit a ruptured pressure relief blister. In either case, it's easy to tell that the starting capacitor is in need of replacement.
"My motor is slow to start. Is my starting capacitor 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."
