Basic DC motors rely on carbon brushes and a commutation ring to
switch the current direction, and therefore the magnetic field
polarity, in a rotating armature.
The interaction between this internal rotor and fixed permanent
magnets induces its rotation.
In an EC motor, the mechanical commutation has been replaced by
electronic circuitry, which supplies the right amount of armature
current in the right direction at precisely the right time for
accurate motor control.
Matters are further simplified by using a compact external rotor
design with stationary windings. The permanent magnets are mounted
inside the rotor with the fan impeller attached
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.
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.
