EC Motor – Principle
With an EC motor the electronic circuitry stands in lieu of the
traditional mechanical commutation meaning the right amount is
being supplied in the right direction at exactly the right time
providing precise motor control

How does this affect energy efficiency?
1. 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.
2. 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.
3. If two motors are producing the same output but one has a
greater power input then you can be sure that the surplus energy is
being dissipated as heat. If an application is designed to remove
heat then it will have to do extra work just to remove the heat
produced by the fan motor itself, so EC fans will improve the
efficiency of the whole system.
