EC Fan What is EC technology?
EC stands for Electronically Commutated, and it combines AC and DC voltages bringing the best of both worlds; the motor runs on a DC voltage, but with a normal AC supply.
EC motors have several benefits. Because EC motors have no brushes, they do not spark or have a short life due to brushes. Other advantages include the fact that they do not waste power because the electronics control the stator; they provide better performance and controllability, and they run cooler than induction motors; In terms of size, small motors can achieve the same output as traditional DC or AC motors.
Power distribution is much cleaner with an EC motor. Brushless DC motors depend on a separate DC power supply. And an AC motor’s power supply usually adds extra cost and complexity. EC motors can connect directly to AC main power supply with their integrated electronics. They do not completely depend on voltage or frequency; hence, small changes in voltage do not affect motor output.
The EC fan is more windy than the AC fan, more energy efficient, and can work in the 70V - 270V voltage range, such as work under on 110V, 115,120V, 220V, 240V ,the fan speed are the same.
