Application

External rotor Fan

Structure

● The motor adopts Hall-less Scheme. The power supply and drive are mounted at the end of motor. Forward or backward impeller is riveted inside the rotor, and the whole unit passes the precise balance test to ensure the smallest vibration feeling by hand. The drive can start or stop the motor when customer supply AC voltage and 0-10VDC speed regulating voltage. Analogue signal speed regulating and PWM signal speed regulating are available for  choice. Meanwhile the speed -regulating of the communication serial port can be customized to realize centralized control.

● The External rotor fan has advantages of high speed, strong wind blow under high static pressure. It is suitable for super-thin fan and special environmental field, and is widely used in FFU fresh air system.
