In one sentence, describe what the following article is about:

Wedge the tip of a flat-blade screwdriver underneath the thin metal tabs, then pull up gently on the handle to lift them enough to loosen the coiled wire. On some motors, there may be as many as 12-16 tabs in total. Try to bend the tabs as little as possible to avoid damaging them. If one of them happens to break off, you may have trouble keeping the replacement windings in place later on. Depending on the type of motor you’re working on and where the problem lies, the faulty windings may be found on either the stator or the armature. Snip each coil of wire where it connects at the top of the protruding posts.  Cutting out the spent windings can be painstaking work. It may be necessary to sever one wire at a time to make removing the coils more manageable. Be sure to count the number of winds in each coil so that you can rebuild the motor in the exact same configuration. Once you’ve cut every last connection, the old windings should come out with a couple of tugs. If you're having trouble getting them started, use the tip of your screwdriver or a pair of pliers for extra leverage.  Before you handle the cut coils, pull on a pair of thick work gloves to safeguard yourself against cuts and scratches. If the coils refuse to budge, it's possible that they haven't been severed completely. Look for connections around the posts or bottom of the coil that you might have missed. First, pull out the old paper out of the slots in the stator using a pair of pliers or tweezers and make sure the empty slots are free of debris. Then, measure the width of the slots and cut a sheet of insulation paper into strips of the same width. Fold the strips gently and slip them into the slots in the stator individually by hand.  If the insulation paper that’s already in place appears to be in good shape (it should be clean and intact), you can simply leave it where it is and begin the rewinding process. If it appears burnt or otherwise damaged, it’s a good idea to replace it before proceeding.  Do not, under any circumstances, attach the new wire directly to the bare steel stator or armature posts. The coils must be insulated at all times. You can order electric motor insulation paper online from suppliers that carry electrical materials.

Summary:
Use a screwdriver to pry open the tabs on the brush pads. Cut the old windings free using a pair of wire cutters. Pull the cut coils free of the armature or stator by hand. Replace the insulation paper lining the stator if necessary.
