TL;DR
Motor rewind
I have an AC brush motor it has 12 slots where copper wires go and 24 copper bars, if you take 12 wires and go in a slot and come out at different slot and as you go around you filled all the slots now you have 24 ends 2 wires out of each slot which you connect to the 24 copper bars. Heres the problem there are 2 wires connected to each copper bar, this means there are 48 ends so you need 24 wires or 4 wires sticking out of each slot, does this motor have 2 smaller wires runing in parreal?

You need to figure this out for your specific motor. The first step in rewinding a motor is to make a clear diagram of the existing winding. That includes the connections from commutator bar to slots to commutator bar, wire gauge, number of turns, how the end turns are laid in place, and more. This diagram is useful as a template of one way to make a rotor winding diagram, but it does not contain all of the necessary information:

Search terms rewind DC brush motor found several good hits.

I once spent a summer working in an electric motor rebuild shop. Take as long as necessary to fully understand the existing winding because you need to exactly duplicate it if you want the rewound motor to actually work.
