1. After the commutator of permanent magnet DC motor runs for a long time under the load, a hard dark brown film will be produced on the surface. This layer of film can protect the surface of the commutator from abrasion, so it should be protected. 2. The surface of the commutator should be smooth and clean. There should be no mechanical damage and spark burn marks. If there are slight burn marks, you can use abrasive paper to carefully grind the surface of the commutator rotating at a low speed. 3. The surface has severe burn marks or rough surfaces. When the surface is not round or there are local bumps, it should be removed and turned again; 4. After use, remove the metal chips and burrs on the surface of the commutator, and finally use compressed air to clean the entire armature surface. , And then assemble.
