What Are The Factors That Influence The Life Of The Synchronous AC Motors?

The electric motor is a device that converts electrical energy into mechanical energy. It is the use of coil (that is, the stator winding) and act on the rotor of rotating magnetic field (such as cage closed aluminium box) form a magnetic dynamic torque, for the life of the motor, I believe is very important for many needs, the following June Motors small series to introduce factors that influence the life of the synchronous AC motors.

What are the factors that influence the life of the synchronous AC motors

Synchronous AC motor life and insulation deterioration or sliding abrasion, bearing deterioration caused by dysfunction of the elements related to the most depending on the bearing conditions. Bearing life is indicated in the following, agency life, oil life in two ways.

1, due to thermal degradation of lubricating oil oil life

2, operation fatigue caused by mechanical life

Synchronous AC motors in the majority of cases, due to heat the oil life the effect of allowing the effect of load on bearing weight on the mechanical life. Therefore, oil life projections motor life, because most oil life is temperature, temperature greatly affects the life time.
