What Are The Factors Affecting The Life Of The Gear Motor?
Effects of load current fluctuations .
If the motor circuit is switched on and switched over frequently, the load current will fluctuate frequently and cause the sharp change in a short time, thus producing obvious additional forces in the current wire and the motor winding, which are related to the current square and act on the fixture through the current conductor. As time passes, the insulation will cause short circuit or broken circuit, make the winding damage and shorten the service life of the motor.
rotation also changes and fluctuations and the impact of the reversal process.
These processes will produce additional mechanical forces in the insulation wire for moving parts, while mechanical connections such as stack group, Xuan shaft, etc., will also produce additional load, so that these moving parts and mechanical connections will be fatigued and lose working capacity.
thermal overload and temperature fluctuations.
Thermal overload will destroy the insulation material, because the highest temperature is directly related to the service life of the insulating material, so the operating temperature of the motor is not allowed to exceed the allowable limit temperature of the insulating material. Temperature fluctuations also have an impact on the service life of insulating materials. The so-called temperature fluctuation refers to the temperature difference between the motor in the cold and thermal state. The above effect is particularly evident when the motor is subjected to the alternating load. Usually, temperature fluctuations will expand the wire, insulation layer and bandage parts to varying degrees, which is also easy to cause off-paint and loosening, the action life of the field range motor.
reducer uses environmental conditions impact.
Such as locomotive motor. Electric motors for mines and chemical industry all work in different harsh environmental conditions and are susceptible to environmental influence and shorten their service life. For example, impure or corrosive gases and higher temperatures damage the electrical and mechanical properties of the motor. Therefore, when choosing the motor, the motor with the corresponding protective structure must be selected according to the environmental conditions. The gear reducer is suitable for ambient temperature of minus 10 degrees to positive 40 degrees and humidity below 90%.
