Most electrical motorsused in household appliances such as vacuum cleaners , wash machines , power tools and more , have an armature with a commutator on top . As the armature spins around the driving force shaft , a carbon brushing on each side of the motor makes contact with the armature . Eventually , these brushes can wear down , causing the motor to fail . If you may get to the top of the motor , you may tally your motor skirmish and change them if needed .

Step 1

Disconnect the appliance ’s power corduroy from the electrical outlet .

Step 2

Remove any housing or electrical panel to gain access to the top of the electrical motor in your appliance .

Step 3

Locate the two brush housings . They should seem like a long , orthogonal tube on diametric sides near the top of the motor , pointing toward the center . Inspect one of the brush lodging . There should be a screw or a snip on the end of the housing that , once removed , will tolerate the bounce - load up brush to be removed .

Step 4

Remove the natural spring or snip , and pluck out the spring - loaded clash . acknowledge exactly how the skirmish comes out of the caparison , as it will need to be put back in precisely the same position . If you put back the brush , the new ones will want to be installed in the same style that the old ones are take out .

Step 5

Inspect the inner C peak of the brush at the close of the springiness . If it looks match or worn , it probably needs to be replaced with new brushes from the manufacturer of the motor .

Step 6

Slip the onetime coppice ( or the new one if the old copse is worn ) back into the brush housing just as it was remove , and tighten the screw propeller or clip to hold the brush into the housing .

Step 7

Remove , visit and return or replace the brushwood on the opposite side of the motor . Then , replace the housing or panel that you removed to reach the brush . Plug in the business leader electric cord , and screen the building block .

Tip

One sign that brushes may be wearing out is if you see some sparks in the motor near the top of the armature .

Warning

Do not seek to convert brushes in an electric motor without first disconnecting the motor from power .
