The motor worked !
  1. But your examination says it is glued ( something I never heardof  ) !
  2. Could you be mistaking a form of electrical contact for glue ?
  3. And could you have stressed the motor to get very hot and then it started to run rough afterwards ?
  4. Is there room ( volumetric space ) to use twist ties in the motor to join these wires ?
  5. How many wires come out of the motor for the AC inverter ??

If the wires look as though they are meant to have an electrical contact, then yes, soldering the joint will improve it. If not, they probably used glue for a reason. You can always unsolder them if you need to, so just start it up on low power and see what happens.

Some photos of the problem, or at least a part number would help people to give you some advice. If it sounds a bit rough while under power, it could be a fault in the driver circuit. If the problem persists while off-load or turning by hand, there could be an issue with one of the bearings.

Without seeing it, the only suggestion I can make about the actual wiring is that the wires may be to do with selecting the configuration of the motor, so don't need to be touched.

Also, you might want to add some more to the title so people know what you are asking.
