Hey Ed, Can We Use the Acronym ECM to Describe All Electronically Commutated Motors?


In this edition of "Hey Ed", Ed discusses if you can use the acronym ECM to describe all electronically commutated motors

Hey Ed, can we use the acronym ECM to describe all electronically commutated motors? No when we should, essentially there is two ECM technologies that we currently use, one would be referenced as a constant torque motor which has a fan curve that's similar to a standard induction motor that we've used for 50 years I think would be a good estimate, the other type of ECM technology that we use as a constant airflow motor, also referred to as variable speed and it maintains airflow hence the name constant airflow and the way those two technologies consume power is very similar they’re very efficient motor, but the way they deliver airflow is not safe, so we have to specify, constant torque or constant airflow and that's the way I see it.
