Foredom 1/6 hp motor brushes are for all 1/6 horsepower M.SR, M.SRM, M.SRB, M.SRH, M.SRMH and M.SRBH models, both 115 Volt for domestic use and 230 Volt for international use.

Earlier models of Series SR motors (built prior to November 2005) are 1/8HP and use different brushes, part number: 2019P. Brushes should be checked for wear periodically.

When new they are approximately 5/8″ long. Replace them when they have worn to 1/4″. Be sure to replace both motor brushes even if one of them is less worn than the other. 1/6 hp motor brushes help your 1/6 horse power engine run smoothly and efficiently by keeping the metal connecting parts lubricated and free of debris build up. 

How The Foredom Brushes for 1/6hp SR Motor Work

Motor brushes help to transfer electrical current from the armature to the commutator, and they also help to brush away any debris that might be on the commutator. Over time, they will wear down from this continuous contact and will need to be replaced in order to keep your motor running properly. Replacing your motor brushes regularly will help to extend the life of your motor.

Motor brushes are one of the most important parts of an electric motor. They are responsible for carrying the current from the power source to the armature or rotor, which creates the magnetic field that makes the motor run.

Motor brushes are made from a variety of materials, but the most common type is made from graphite. Graphite brushes have low resistance and low friction, which helps to prolong the life of the motor. In addition, they are easy to replace if they wear out. For these reasons, graphite brushes are the preferred type of brush for use in electric motors.

What Are They Made Of?

Foredom motor brushes are specially designed to provide long brush life and consistent performance in Foredom flexible shaft tools. The heart of the motor brush is a flexible copper pigtail that's imbedded in the brush and terminated in a U or disc terminal. Surrounded by a coil spring, the pigtail ensures proper brush pressure on the commutator as the brush wears.

The free end of the brush is curved to match the curvature of the commutator, and when the brush is inserted in the brush holder and the screw cap is in place, the pigtail contacts the inner metal tube to provide a current path to the brush.

Foredom motor brushes are available in a variety of sizes and styles to fit your specific Foredom tool.
