How do you lubricate an electric motor?

What is the best lubricant for an electric motor?

A NLGI 2 grade grease is the most commonly used in electric motor applications. ASTM D 3336 oxidation life. require a grease with an EP additive. Dropping Point: The dropping point gives an indication of the temperature at which the grease will melt or the oil will separate from the thickener.

Is WD 40 safe on electric motors?

Yes, it can as WD 40 has oil base which can make winding insulation more weaker and can damage your motor. Also, WD 40 is not recommended to be used over electrical contacts.

Should I lubricate an electric motor?

Expert advice: When oiling an electric motor, be sure to use oil that’s specifically designed for motors. When oiling an electric motor be sure to use special oil for lubricating electric motors. Other oils could cause excess wear and premature failure.
