Cleaning / Polishing / Dressing Of An Electric Motor Commutator #Repair #DIY #HowTo

Today we show you a way to clean and polish the commutator of an electric motor. The electric motor seen in the video belongs to an electric drill I have found in a crate with its motor opened. I do not know what has caused the grooves on the commutator but they need to be removed for the motor to work properly.

► YOU WILL NEED
- Cleaning rag
- Sponge
- 400 or better, 600 grit Sand paper (aluminium oxide)
- Cleaning gear: Brush / air compressor / vacuum cleaner

► DISCLAIMER
Always make sure you operate in a safe and secure manner.
For this project, take your time, work slowly and check progress.
It is essential to thoroughly clean the motor after polishing the commutator since fine metallic particles left may create shorts in the engine.
