EC Fan Introduction
EC(Electronically Commutation) motors, as built-in DC inverter
driver three phase AC external rotor permanent magnet synchronous
motors, its efficiency and low noise is considered to be ultimate
fan energy technologies.
Core Technology Of EC Fan Controller
1. Sensorless vector control software
2. High-performance power electronic circuits
3. Security and reliability design(Standards, Certification)
4. Embedded design

How does this affect energy efficiency?
Doubling the speed of a motor increases its power input by a factor
of 8 so it’s very wasteful to run a fan faster than is required. If
you can tailor the fan speed to match the demand, the potential for
energy saving is huge. Even when compared to on/off operation, EC
speed modulation is much more efficient.
EC fans can also contribute to increasing the overall efficiency of
an application. In a cooling system for example, keeping the
refrigerant pressure constant rather than having it rise and fall
as fans switch on and off has been found to reduce the load on the
compressor resulting in even greater energy saving.
