What is a Fan Motor & What Does it Do?
The objective of your air conditioner's condenser fan electric motor is to keep the compressor from overheating. Its job is to great the superheated refrigerant that movements through the condenser coils of your Air conditioner, which helps to cool your home.
How really does an AC motor function?
Unlike in a DC motor, where you send power to the internal rotor, within an AC motor you send capacity to the outer coils that define the stator. The coils are energized in pairs, in sequence, generating a magnetic field that rotates around the exterior of the motor.
How long will an AC fan engine last?
Usually, you can expect your air-con system to last anywhere from 10-15 years - in other words, the life of your automobile. The AC system is a sealed unit, and very little can go wrong.
What would result in a fan to avoid working?
Check the Fan Fuse
Like the circuit breakers in your house, these fuses are created to break the electrical connection when too much electricity causes your fan to overheat. When the 
fuse melts, it breaks the bond and cuts power to the enthusiast. Check the cord and the inside of your fan for this fuse.
How do you maintain an AC enthusiast motor?
Annually
Remove and renew grease in ball or roller bearing.
Test insulation.
Clean out magnetic dirt that may be attached to poles.
Check clearance among shaft and journal boxes of sleeve bearing motors.
Check the commutator intended for smoothness and slot harm.
Examine connections of commutator and armature coils.
