How to maintain the generator?
(1) commutator maintenance: ① if there is a slight burning marks, you can use No. 00 emery cloth in the rotating commutator on the fine grinding; ② such as the commutator surface serious burning marks and rough, the surface is not Round or partial convex and concave phenomenon, you should remove the armature in the lathe heavy truck; ③ commutator under long-term operation of the load, the surface will produce a layer of hard dark brown film, this film can protect the change The device is not worn, so to save this layer of film, should not be worn.
(2) Brush and slip ring maintenance: ① brush and commutator (or slip ring) should be good contact, the normal pressure of 0.15 ~ 0.25kg / C ㎡, brush and brush with the grip frame should not be too tight , And need to leave no more than 0.15mm gap; ② brush wear or fragmentation, the need to change the same specifications of the brush, the new brush assembly should be smooth after grinding to achieve with the commutator (or slip ring ) Coincides with the contact surface.
