The grease consistency preferred for electric motors is normally NLGI 2 or 3, with a base oil viscosity of 100-150 cSt @ 40°C. … The preferred thickener for most electric motors is polyurea. However, aluminum complex, lithium complex or calcium sulfonate thickeners are also good options.
How can I make my electric motor quieter?
Capacitors are usually the most effective way to suppress motor noise, and as such we recommend you always solder at least one capacitor across your motor terminals. Typically you will want to use anywhere from one to three 0.1 µF ceramic capacitors, soldered as close to the motor casing as possible.
Can you use wd40 on an electric motor?
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.
What damage can be caused by over greasing?
Overgreasing can lead to high operating temperatures, collapsed seals and in the case of greased electric motors, energy loss and failures.
