1. EC is easy
Permanent magnet motors running on high voltage direct current (DC) electricity with built in AC to DC conversion allowing them to run direct from single phase or three phase mains supplies. There are several suppliers of such motors
Control options
To control the motor accurately and efficiently the integrated electronics have to continuously monitor the motor speed and adjust the control input. By making this circuitry available to external sources it’s possible to provide simple speed control options. Dependent on the motor type, any sensor which can provide a 0-10V/PWM or 4-20mA input can be directly connected to provide closed loop control for temperature, pressure or whatever parameter you choose to measure. No need to worry about DC supplies for the sensors either, this is provided by another connection on the motor. In fact, simply connect a potentiometer and you have infinitely variable speed control. No triacs, no frequency inverters and no whining noises! An EC motor under speed control is virtually silent.
How does this affect energy efficiency?
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
