Electronically Commutated Motors (ECMs)

Electronically commutated motors (ECMs) have quickly become standard in the HVAC industry. They can have unexpected operating characteristics that are very different than their predecessor; the alternating current (AC) permanent split capacitor (PSC) motor. An ECM is a brushless, direct current (DC) motor that operates at a synchronous speed. ECMs utilize integral inverters so they … Read more
