AAAARRRRGGGGHHH !!!!!!!!!!Soldering prob.

[BrianG]

Typical motor wires are simply the extensions of the coil wires and so have an insulating varnish coating on them. Makers leave the last ~1/2" unvarnished to solder, but if you cut that off, you are gonna have a heck of a time soldering to them. You will need some kind of solution to dissolve the varnish off the ends. Just be careful to keep the solution from wicking up into the motor, because if that happens, the only thing it would be good for is a refrigerator magnet.
