FAQs:
Q: What are the advantages of an EC fan motor over a regular AC fan motor?
A: An EC (Electronically Commutated) motor is in fact a brushless, permanent magnet DC motor which is controlled electronically. The AC supply is rectified to DC and directed to the motor windings to achieve rotation and the optimal torque. In simple terms:

• The speed of the motor is infinitely variable (i.e. any speed from zero to maximum speed can be selected precisely, rather than chosen from a pre-set range).
• The energy efficiency of the motor is far superior to AC motors, using only the power required to produce the required speed.
• The motor runs far more smoothly and quietly than an AC motor regulated by a speed controller.
• Less heat, less noise and less stress on the motor contribute to greater motor longevity.
