Top 4 Benefits of EC Fans
An electronically commutated (EC) fan design delivers the combined benefits of AC and DC Fans . The EC fan's power comes from a brushless DC motor, but it offers the control that AC induction fans have over the fan rotor through a printed circuit board. The electronically commutated fan's DC motor has the advantage of a variable speed control built-in. An AC electrical supply powers the EC fan, but the on-board electronics convert the power to DC before reaching the motor. The secondary magnetic field generated by the permanent magnets makes EC fan motors considerably more efficient than AC induction motors. This blog post will discuss the four primary benefits offered by electronically commutated fans. Increased Efficiency The high energy efficiency of the EC fan motor comes from the reduction in energy consumption. Even at partial speeds, EC fan motors continue to maintain high levels of efficiency. The secondary magnetic field in EC fan ...
