Here are some photos of the brushes installed on my DC FB1-4001A series wound motor, rated at 72-144 VDC, (19kW) 25HP continuous ( 100 ft\/lb of torque \/ 48hp @ 500 amps ) which is \u00a0 9.1″ in diameter.<\/p>\n

My motor has a curved protective metal sheet that wraps around the front of the motor (the aluminum with diamond cutouts that has a cutout for the A2 post in this photo). It has a spring catch that releases it (not shown) on the other side of the motor.<\/p>\n

\"\"<\/a><\/p>\n

I use the metal sheet to hold down fiberglass screen material underneath the diamond cutouts to provide extra protection from road debris. The brushes are accessed after removing the sheet.<\/p>\n

\"\"<\/a><\/p>\n

The brushes are mounted in pairs, and each brush is held against the commutator by a metal spring and has two copper pigtails to transfer the current.<\/p>\n

Here is a closeup of two brushes where you can see the commutator which rotates under them.<\/p>\n
