Reworking the commutator after the formation of grooves

Moderate scoring or burn marks do not affect the operational reliability of the machine. The

commutator only needs to be overhauled if it is seriously scorched or grooved and/or is out-of-

round.
● Grind the commutator in the mounted position with a commutator grinder of medium grain

size, grain number 80 (210 - 177 μm).

● To do this, lift most of the brushes and operate the motor at a speed of approximately 600

rpm.

● Place the grinder on the brush holder.

Note
Suck or blow the dust out
Dust inside the motor can cause winding damage. Suck or blow the dust out.

● Remove the grinding dust with dry, oil-free compressed air. Deburr the edges of the

segments if necessary.

● Where the commutator is severely out-of-round, remove the rotor and skim the commutator

on a turning machine. You can skim the commutator down to the smallest permissible

diameter (d

min

) given in the following table.
