The article evaluates the potential of electric commutated (EC) fan motors in boosting energy efficiency of ventilation and air conditioning systems. EC motors are run through a direct current voltage by a commutation electronics, where their intermediate circuit capacitors smoothed the rectified alternate current voltage. The EC motors by GreenTech has features that are unique on other motors, where they can cut current harmonics and can provide effective power draws in standby mode.
