What is the best oil for electric motors?

Mineral oils are adequate for most electric motor bearing applications. However, synthetic base oils may be required for extreme temperature applications or where longer regreasing intervals are desired. The thickener primarily serves as a carrier for the oil and prevents it from leaking out of the application.

What is the best lubricant for an electric motor?

Electric motors require lubricants with specific characteristics. Use of the wrong grease often leads to early electric motor failures. The grease consistency preferred for electric motors is normally NLGI 2 or 3, with a base oil viscosity of 100-150 cSt @ 40°C.

Can a commutator be repaired?

Mold-type commutators are not repairable and must be replaced if damaged. When a commutator comes in for a repair, units are disassembled and rebuilt with new copper and mica segments using the same quality assurance processes applied to new commutators.
