SECTION 3 - BRUSH THEORY AND CHARACTERISTICS

Question 3:13 Is It Good To Let A Motor Run On No Load?

 

Some people believe running in new brushes on no load is a good idea but, as a general rule, this is not advisable as current flow is particularly important in the build up of temperature and the composition of the patina. Running with only mechanical friction may cause glazing of the commutator surface and do more harm than good. 

 

In an ideal world it would be nice to bring a machine up to full load gradually to let the brushes settle in but this is rarely practical.

 

Although the running in of brushes to achieve the full polished face condition can take a few days of continuos operation, motors which have the brushes properly bedded in, and brush gear set up correctly, can go onto normal load immediately and will usually develop the patina without any additional procedures. A clean with a rubber bonded cleaning stone may occasionally be needed if the Patina is building up unevenly.
