Three-phase asynchronous motor overload for a long time, lose insulation aging of insulation effect; Wire insulation damage; Winding be affected with damp be affected with damp decreased insulation resistance caused by insulation breakdown; End and not cushion layer insulation material or plastic damage; End connection wire insulation damage; Or been struck by lightning overvoltage insulation breakdown; Friction between rotor and stator winding end insulation damage; Too many metal foreign bodies fall into the inside of the motor and oil pollution.

The fan is usually the wind hood, motor and wind leaf of three parts, including motor as outer substructure, exterior rotor motor compared with the inner rotor motor its advantage lies in the structure stability, good protection, little vibration, low noise, reliable running. But due to the high power high speed for a long time, often can appear the motor load is too large, if special electric fan captain time in the high load condition, can cause irreparable damage to the motor.

At first, because of the auto industry decided to diamond coil as a best coil type, so using adjustable wooden model is common. Process is completed, around the original coil winding machine will use the leather made wooden hammer will coil model. Despite the coiler have made every effort, but the manual and very physical process means difficult to achieve consistency.
