What is EC technology? EC stands for Electronically Commutated and it combines AC and DC voltages, bringing the best of both technologies. The motor runs on a DC voltage, but with a normal AC supply. DC motors already have low power consumption but if used in an AC application. The power needed converting AC to DC, using a bulky, inefficient transformer. The EC motor incorporates voltage transformation within the motor. The non-rotating part of the motor (stator) is extended to make room. For an electronic PCB board which includes power transformation AC to DC, as well as the controls.
