The first part of Senli motor Xiaobian for everyone to tell a simple storyThree-phase asynchronous motorInsulation materials and temperature rise, the impact of temperature rise on the life of asynchronous motors, today we will talk about the impact of environmental temperature and other factors, will cause what damage to the motor.
In the normal production operation of three-phase asynchronous motor products, theoretically under the rated load, its temperature rise and the ambient temperature is not much impact, but in the actual production work, in fact, is affected by the ambient temperature, when the temperature drops, the normal motor temperature rise will be slightly reduced, this is because the winding resistance is reduced, copper consumption is reduced; Like some self-cooling motors, the ambient temperature increases with each increase10℃Then the temperature will rise1.5-3℃Around, this is because copper loss increases with rising temperatures.
The humidity in the air also has an impact on the temperature rise of the motor, and the humidity is high10%, becauseThree-phase asynchronous motorInternal thermal conductivity change-Good, the temperature will drop0.2℃Around; As the motor specifies the altitude range to1000mAltitude is the standard if ascending100mThe temperature rise will increase the limit value1%.
The temperature of rolling bearings generally does not exceed95℃To be appropriate, the temperature of the rolling bearing is not excessive80℃Because if the temperature is too high, it can easily lead to changes in oil quality; The surface temperature of the casing is not hot. Like the surface stray loss of the squirrel cage rotor is large, so the temperature rise is generally relatively high, and generally does not endanger the adjacent insulation.
