Commutator Grinders morgancarbon

2017-8-24  The Martindale Commutator Grinder assures concentricity of the commutator or slip-ring by precision grinding while it is turn-ing in its own bearings at operating speeds and temperatures, with centrifugal force holding each bar in place. Either tool (Fig. 1 or 8) can be quickly changed from right to left hand operation.

In the absence of this tool, the second preferred method is to use a grinding stone and to turn the commutator. This operation would also be performed in the motor shop. If the commutator is not too far out of round, and the motor needs to be back on the line quickly, a handstone specified for smoothing commutators can be used.

Method for trueing commutators and slip rings

The grinding wheel on the motor shaft is traversed across the face of the spinning commutator or slip ring on a compound mount. Use of a 6 inch 150 to 180 grit grinding wheel, for example, safely operable at least at 4,500 rpm produces a surface speed of at least 7,000 feet (2,100 meters) per minute.
