For Exhaust fan cooler motor, the closed-loop control of its drive system can directly feed back the signal of motor encoder, and sample and analyze it. Moreover, position loop and speed loop are formed inside the fan motor, which makes the control performance more reliable.
Exhaust fan cooler motor is a capacitor operated motor with large power factor, good starting performance, high efficiency, strong overload capacity and stable operation. At present, most fans are capacitor operated motors. The fan motor has excellent speed overload and torque overload capacity, with strong performance. Because of its good low-frequency characteristics, it can effectively avoid low-speed vibration.
Commercial exhaust fan , Electric fans, washing machines, refrigerators, air conditioners and other household appliances are used single-phase asynchronous motors.
