24V 48V speed control electronically commutated EC external rotor motor in HVAC

100% controllable by 0-10V/PWM, available in 115V/230V/380V AC input or 12V/24V/48V DC input for centrifugal or axial fan blower What is an external rotor EC motor? Electronically Commutated (EC) motor is combines AC and DC voltages, bringing the best of both technologies. The principle is permanent-magnet brushless DC motor within the rotor, the stator is driven by electronic switches (which replace the Carbon brushes), controlled by a micro-controller..The EC external rotor motor is very compact because of its integrated bearing system which is particularly suited to meet the requirements of air moving solution. The integration of the motor inside the impeller results in extremely compact designs and high performance density. All rotating parts are directly finned to one component and dynamically balanced. This guaranteed low loads of the bearing systems. The high efficiency helps to keep the energy costs at a low level. Temperature rise is low since an EC motor generates approx only 1/3 of the heat loss known for conventional AC single and three-phase motors. This contributes to long motor life.  The electronics can be either integrated onto a PCB inside of the motor of can be separated unit.

How are EC motors “energy saving”?

EC motors are very high efficiency (65% to 80%) electric motors and maintain a high efficiency level at part speed. This means that in most cases they use from less than one third to one half of the electricity used by shaded pole or PSC induction motors used in the ventilation and refrigeration industries, which in turn translates into lower operating costs and short payback periods.
