No matter what equipment or products, as long as the movement friction, it needs to be maintained, electric motors are no exception, if you want a motor to work well, then grease is essential, the lubricant for each kind of equipment is different, so how should the motor choose grease.

1, the motor can also lubricity, anti-wear good, not dump oil, not dry, not emulsified, not lost, grease itself should not contain solids.

2, working temperature, when the working temperature exceeds the grease allowable working temperature, the temperature rises by 10 degrees each, the grease life will be halved; when the grease base oil loss of 50-60%, the grease lubrication capacity is basically lost, so for the motor running temperature, must choose good anti-oxidation, small heat evaporation loss, high drop point of quality grease.

3, good oxidation resistance, after long-term use, the appearance of grease colour, acidity and alkalinity change is small, no obvious oxidation phenomenon.

4、Good fluidity, general requirement of using temperature in -25℃～120℃, small starting torque, low running torque, low power consumption and low temperature rise.

5, rust resistance, salt spray resistance, good water resistance, can be applied to the harsh working environment.

6、Filling volume, generally filled to 1/3 - 1/2 of the volume, low speed motors can be filled to 2/3.

7, suitable consistency, has a good vibration damping effect, can reduce the noise of the motor bearing, is conducive to environmental protection.

8、Motor can be selected for good adaptability, with high and low temperature performance, can be common in indoor and outdoor, south and north.

9, long service life, can extend the maintenance cycle, reduce bearing consumption.

The above is how to choose the motor grease sharing, if you want to know more information about it, please pay attention to this site.
