[Editor's note: As most readers of this blog already know, one of the legacies of President Obama's administration will be the enacting of new energy efficiency standards for the electric motors that run numerous appliances, both residential and commercial. Some of these standards are already in effect and the clock is ticking on compliance; others will go into effect in the next two years. Here's a link to a tool on the Department of Energy website that offers much more detail about guidelines and compliance.
The following post was originally posted in July 2015. We are planning future blog posts about Electronically Commutated Motors (ECM) over the next few weeks to talk about why now is the time to move forward in addressing your compliance needs.]
What's the difference between a Permanent Split Capacitor (PSC) motor and an Electronically Commutated Motor, also known as an EC Motor or ECM? A PSC motor is one of the most commonly used motors that can run at single or variable speeds. An ECM is much more energy-efficient than a PSC and features an internal smartboard for better motor control.
