Energy Conservation MeasureElectronically Commutated Motors (ECM)Fan Speed Controller

An Electronically Commutated Motor (ECM) is more efficient than a motor that uses the shaded pole or Permanent Split Capacitor (PSC) type technology. This is due to the fact that the motor is a permanent magnet motor which has fewer losses than a standard induction motor. With an integrated electronic control, similar to a Variable Frequency Drive (VFD) in larger applications, the motor can be programmed to operate in various modes. For the fan powered terminal boxes, the motors are programmed for either a fixed torque or variable speed, depending on the desired control method or desire to integrate with a building automation system.

The fan speed controller will allow for precise airflow/CFM to be dialed into individual terminal boxes in order to meet airflow/CFM requirements at a localized area and/or help balance the building airflow/pressure. A fan speed controller can also work with a building automation system
