Efficiency Refrigerator Cooler Axial Flow Fan 12V DC Brushless Cooling Fan

Product Description

Product Description MD9225 DC Fan MOTOR specifically designed for refrigeration and air conditioning systems. lt provides superior efficiency, precise control, and long-lasting reliability for demanding applications.
Features:
1. Characteristic
Characteristic is measured by rated voltage, rated frequency, the value of the characteristic must be in standard value in the characteristic table.
2. Insulation
a. Insulated resistance
The insulated resistance must be more than 200MQ at the time of normal temperature and humidity.
b. Electric strength
The motor is under 1500VAC for one minute or 1800VAC for one second.
c. Damp proof
The insulated resistance must be 100MQ or more when the test piece is exposed to the temperature of 40±3C and humidity of 90% for 48 hours.
3. Life
When driving at the normal rated ,normal load conditions, continuation drive is possible, the operation time is 60000 hours or more.
4. Supply voltage
When the supply voltage changes at the rate of±10%, the motor keeps operating normally.
5. The lead wire tension strength
When the lead wire is pulled at the force of 5.0N per one wire for 3 second, it must that no failure occurs on the connection.
6. Temperature condition
The temperature for use:-40ºC~60ºC .
7. Relative humidity
The relative humidity in the dampest month is 90% (The lowest temperature every month is 25ºC or less.)
8. Noise
When the motor is operating under no load, the noise is less than 45db(A)
Measuring Manner: Taking the corresponding motor to the Un-echoic Room, obtains internal environment noise is 10dB first, again uses a decibel reflectoscope reflector to survey the motor's sound, demonstrated the data subtracts the environment noise, is the motor's noise.
As long as you are a manufacturer of super-market refrigeration equipements, or beverage cabinets, or beer coolers etc, you will be in need of our electric motors for Fan.
