External Rotor Brushless DC motor for Fresh air system.
● The motor adopts Hall-less Scheme. The power supply and drive are mounted at the end of motor, it 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 outer rotor motor is a new-type product. Compared with the inner rotor motor it has advantages of high efficiency, large output power, low noise and compact installing structure. It is suitable for the super-thin fan and the special environmental ?eld.
