What Kind of Oil is Motor Lubricant?

[DiGage]

Motor lubricant is composed of a semi-solid base oil, thickeners, and other additives. It not only reduces the friction resistance during motor operation but also protects against the effects of climatic conditions. To choose a lubricant that protects motor bearings, it should possess the following performance advantages: High-temperature lubrication performance and low grease volatility: Motor bearings, especially those near the output side, often operate in ambient temperatures exceeding 95°C. Therefore, the lubricant must maintain good lubrication under high-temperature conditions and should not experience significant grease loss due to heat. Corrosion protection: Motors operating in relatively high-temperature environments often generate water vapor, making the bearings more susceptible to corrosion, particularly in applications with intermittent operation. Thus, the lubricant is essential for providing corrosion protection to the bearings. Low-temperature startup performance: In certain usage scenarios, such as snowy winters, the friction resistance during startup can increase significantly. In such cases, a non-congealing lubricant is needed to help reduce startup resistance at low temperatures.
