Brushless dc fan use a permanent magnet excitation, eliminate the loss of induction motor excitation currents; realizing the small loss an high efficiency characteristics
Compared with the frequency control of induction motor, brushless dc ,motor is simpler and more controllable, easy to perform control
The components, such ac inverters etc, whose capacity is low, and circuit are simpler, the cost lower than ec blower’s
Furthermore, the electronically commutated motors are extremely quiet and operate at efficiencies of
up to 90 %. Thus they attain significantly higher values than most voltage-controlled asynchronous
motors, which have typical efficiencies of between 30 % and 60 %. At the same operating point, therefore,
the power consumption of the EC fans is considerably less.
With integrated motor electronics, the EC fans can be easily speed controlled via a 0-10 V signal or by
the use of a potentiometer. As an option up to three air flow values can be programmed in "Constant
Flow" mode.
OFAN provides the most comprehensive services, includes: product diversification, against the clock delivery, documents support, and technical consulting service. “Customer is partner” is key to our success; ”Win the contract for customer” is our ultimate goal.
Additional Functions
Constant pressure : Used in conjunction with a pressure sensor, the fan maintains the same pressure at varying airflow (ideal for ducted applications).
Operates with forward curved centrifugal fans without pressure sensor and with backward curved motorised impellers with pressure sensor (Available on Ecofit fans).
Constant airflow : The fan maintains the same airflow at varying pressure (ideal for filtered applications) (Available on Ecofit fans).
0-10VDC / PWM output : EC motors can be controlled by a simple, standard 10kOhms potentiometer on the integrated 0-10VDC output (Available on both Ecofit & Rosenberg fans)
Hall effect : A tachometric output is available, which can be used for an optional alarm relay (Available on both Ecofit & Rosenberg fans)
