What kind of oil do you use in an electric motor?
The grease consistency preferred for electric motors is normally NLGI 2 or 3, with a base oil viscosity of 100-150 cSt @ 40°C. Other characteristics to look for include good channeling characteristics, low oil bleed, oxidation resistance, anti-wear additives, and mechanical stability.
Should you oil an electric motor?
Without proper lubrication, it will cause the bearings to wear out prematurely. Here are a few pointers on how to lubricate your electric motor’s bearings.
Can you use wd40 on electric motors?
