Durable AC Motor Factory

The motor life is generally in 15 years to 20 years, the motor life depends largely on the maintenance of the user, the use of the environment, and the use of motor in the use of electricity, magnetic, thermal, vibration and other factors. Specific motor should be specific analysis,


For small and medium power DC motor, motor permanent magnetic DC motor (the power except, don't talk about their life people), insulation life depends on the commutator and winding, bearing damage and brush polishing can be replaced, even after Yu Yongci demagnetization again rushed magnetic, which prolongs the service life of the motor. It is cheaper than buying new motor;


The single phase asynchronous, synchronous motor life, mainly depends on the motor in use by electric, magnetic, heat, vibration, environmental conditions, and users for maintenance, their life is damaged, it's the end of winding life. Usually take care of, and the selection of motor capacity, and the type of installation, will make the service life of the motor to achieve the design service life, even far more than design life;


The reasons are summarized as follows

1, the motor itself design temperature rise, if the motor design temperature rise is too high, plus the ambient temperature if exceed the insulation limit temperature, the motor life will be greatly reduced.

2, bearings, bearings, poor quality, short life, will lead to short life of the motor. The main reason is the mechanical failure of the motor life.

3. Insulating materials. The insulation material quality is poor, the motor temperature limit is reduced.

4. External voltage.

5. Environmental conditions and working conditions.
