Avoid other lubricants – and tell your customers not to attempt to lubricate their motor with anything but motor oil.

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.

What spray is good for electrical connections?

The terminals and electrical connectors can be treated with a spray of WD-40® Specialist® Fast Drying Contact Cleaner which eliminates various types of residue and condensation on electrical or electronic equipment, including delicate materials.
