1. An overview of axial fans with external rotor motor

1. YWF series axial fans are external rotor motors. These motors have characteristics of compact structure, convenient installation and high efficiency.

2. YWF series external rotor motors have two kinds, single phase asynchronous capacitor fan motor and three phases asynchronous fan motor. They are suitable for commercial freezer and cold storage, ice machine, air cooling machine, water chiller, condensing unit, central air-conditioning and heater, etc.

3. The insulation class of motor is F or B, and the protection class of that is IP54 or IP44. All motors have thermal protector in the winding.

4. Voltage: The voltage of the single phase motor is 120V/60Hz, 220V/50Hz. The voltage of three phases motor is 380V/50Hz, we can also supply other fan motors with connection box for clients' choices.

5. The axial fans are available with fan guard grill and without guard grill, operating with 200mm to 900mm diameter fan blades.

6. The useable ambient temperature is from -30°C to 60°C.

7. The service life of motors is more than 30,000 hours.

8. Before operating the motor, make sure to put the earth wire of the motor connected with the external grounding device.

9. Most of External Rotor Motors have passed UL, CE approval in Europe and CCC safety certificate in China.
