As the rotor is mounted to interior, the external rotor fan is more compact constructed, smaller and easy to abstract heat., thus ensure to maximum the reliability of fan operation,
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
The basic parameters of field programmable: Maximum speed, minimum speed, maximum power, maximum current, resonance avoid
Constant air pressure controlling function
Embedded design
Electro magnetic compatibility (EMC)
