YWF series External rotor Axial Fan are external rotor fan motors with characteristics of compact structure, convenient installation, reliable operation, low noise, energy saving and high efficiency.
They are divided into single-phrase asynchronous capacitor fan motor and three-phrase asynchronous fan motor which are widely used in condensers, evaporators and other refrigeration equipments and ventilating cycle areas.
The insulation class of the YWF series axial fan motors is B, and the protection class of that is IP54. Each of the motor has a thermal protector in its winding.
Voltage/Frequency: The voltage of the single-phrase motor is 220V/50Hz, and that of the three-phrase motor is 380V/50Hz. We can also supply other fan motors with different voltages and frequencies according to clients' requirement.
The applicable environment temperature of the fan motors used in condensers is from -30 oC to +60 oC, and that of the fan motors used in evaporators is from -40 oC to 60 oC.
The average working life of motors is more than 30000 hours.
All motors in our factory have attained CE approval in Europe and CCC safety certificate in China.
