For most of us, small motors are the unsung hero of the motor world. Their main purpose is...simply to work. We only pay them attention when they start having issues and shut down.
Since the US passed motor efficiency legislation in 2015, the market of run capacitors have changed. This law made a new requirement that 2 capacitors are needed for each small motor, to increase efficiency. This will increase both up-front cost and complexity for this key part. Not to worry, knowing just a little bit about capacitors will put you in the know and make the change something to welcome.
Small motors generally have one start capacitor that helps bring the motor up to speed when it's using all of its force to start a pump, compressor, or other machine. Adding run capacitors can often increase efficiency, by ensuring that excess electricity is absorbed and used when electrical delivery may "lul" in later moments. This keeps electricity from being lost as waste heat.
The United States Department of Energy (DOE) estimates that, on average, motors with 2 capacitors can increase efficiency by 1 & 1/3 percent, and this change will save the US $35 billion in energy production over the next 30 years. This means that you are likely to save money over the life of your motor, and decreased heat throughout the life of your device. This also means that potential failures of additional capacitors may require future purchases of replacement capacitors. As always, please be sure to contact a professional for capacitor installation, and check all dimensions and specs to ensure that you are buying the right capacitor. If APR doesn't have your capacitor in stock, send us an email and we will let you know what other website does...even if it's a competitor.
