What type of grease do you use on 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.
Can I lubricate an electric motor with wd40?
Yes, WD-40 is safe to use on electronics. It is used frequently to dry out auto ignition systems as it it non-conductive, displaces water, and lubricates the parts without getting sticky. I also use it to clean up and dry out computers and power supplies.
How often should a motor be greased?
In general, for oil bath lubrication where the operating temperature is 50°C (120°F) or less, oil should be replaced once a year. When the operating temperature is between 80°C – 100°C (176°F – 212°F), oil should be replaced at least every three months.
Why do electric motors not need oil?
Vehicles that run completely on electric power don’t require oil changes. This is because they lack the internal combustion engine found in gasoline-powered model. An electric car like the 2022 Chevy Bolt moves thanks to electric motors and a battery.
How often should electric motor bearings be greased?
Using the chart and the formula, the bearing only needs 8 grams of grease every 10,000 hours. If your grease gun delivers around 1.35 grams per stroke, that means the bearing needs 6 strokes every 13 months; you could average it out to a stroke every 8 weeks or so.
What is the most popular way to grease an electric motor bearing?
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.
Why use polyurea grease in electric motors?
The new grease helps bearings run cooler and last longer, increases motor efficiency by decreasing drag, and offers excellent mechanical stability for a long service life – even in high-moisture environments.

How can I make my electric motor quieter?
How to Reduce the Electrical Noise
- A disk varistor (D/V), a disk capacitor, a rubber ring resistor (RRR), and/or a chip capacitor to the inside of the motor ⇒Effective for higher frequency band.
- Electrolytic or ceramic capacitors and/or the choke coil to the outside of the motor ⇒Effective for lower frequency band.
Can you use silicone spray on electric motor?
DO NOT USE SILICONE SPRAY ON ELECTRICAL CONNECTIONS, SWITCHES, RELAYS, ETC. There have been numerous reports that silicone spray can cause contact problems in switches, noted in multiple posts regarding automotive problems.
