Description: Electronically Commutated Motors (EC Motors) also known as Brushless DC Motors (BLDC) are synchronous electric motors powered by direct-current (DC) electricity and having electronic commutation systems, rather than mechanical commutators and brushes. The current-to-torque and voltage-to-speed relationships of BLDC motors are linear. As mentioned EC Motors are always synchronous & the conventional AC motors are not synchronous.
Unfortunately, EC motors are inherently more expensive to produce due to the addition of an electronic commutation circuit, however, with advances and demand in the semi-conductor markets increasing, the controls are often straightforward and relatively low cost. Centrifugal ventilation fans with brushless dc motor can adapts the market development trend.
