Does anyone know where I can buy a commutator cover for an ADC FB1-4001A 9 inch electric DC motor? The perforated metal band that goes around the commutator. I think it’s also called a brush cover screen and cover band, funny enough.
Cut out a template out of paper until it fits nicely around the motor. Then trace it onto a piece of galvanized sheet metal and cut out using shears. Finally daisy chain a few hose clamps (unless you find a huge one that fits all around) it to fix it to the motor. Just wear decent gloves when working with sheet metal, and ideally debur the edges after you cut it out so it's not razor sharp.
