(ECM). EC motors have higher efficiencies with considerable energy savings over a standard permanent split capacitor motor. The ECM offered in RenewAire energy recovery ventilators (ERVs) are constant torque with a variety of speed control options. The motors operate at fixed speed or variable speed with speed inputs from fixed resistors, potentiometer, or 0–10 Vdc... -
