Brushless dc fan use a permanent magnet excitation, eliminate the loss of induction motor excitation currents; realizing the small loss an high efficiency characteristics
The components, such ac inverters etc, whose capacity is low, and circuit are simpler, the cost lower than ec blower’s
Variable speed control of dC fan can be realized / achievedvia 0-10V speed adjustment and/or external circuit impulse modulation
EC fans includes AC input driven brushless DC fan with integrated design of AC-DC transformation circuit, the PFC circuit, the BLDC drive circuit, interface circuit. Due to the internal integration of the AC-DC converter circuit, the consumption of power will be reduced to facilitate the design and application of the overall power system in customer
