Ec, exterior rotor motor ec axial flow fan, dc brushless type centrifugal fan
EC fan can be divided into two kinds, one kind of EC fan power for ac 220 V, DC fan, we call this the EC is another kind of EC fan power supply for DC power supply, we call it a DC DC fan, power for 12/24/48 V.
Brushless dc fan characteristics
1. Energy saving
EC motor efficiency compared with the AC motor efficiency is much higher, the traditional AC motor energy saving 30-40%
2.0 100% speed regulation
By 0 to 10 v or PWM control, realize the linear speed.
3. Low noise
Due to the characteristics of motor itself, compared to the EC motor AC motor is running, low noise
4. With output feedback signal, and can realize centralized control
Air volume range: 500-3800 m3 / h
EC backward centrifugal fan series, has the following features:
1. Which has the function of ac input dc brushless fan, with the ac/dc conversion circuit, PFC circuit, BLDC drive motors integrated circuit, interface circuit design.
2. The fan has built-in ac to dc conversion circuit, can dispense customers in the power part of the investment, facilitate the overall power system design and use.
3. The motor is through the electronic commutator (with position sensing, without position sensor) for motor winding current commutation, speed control was achieved by PAM or PWM control, no mechanical brush dc motor (commutator).
4. Can choose according to the requirement of the customer load fan and fan with different levels of power system, guarantee the price with the best performance.Storm of shenzhen technology co., LTD.
