The QC nut (collar) is attached to the end of the spindle. I think you are confusing the terms ''quill'' and ''spindle''. The spindle is inside of the quill, the spindle turns, the quill does not.
Turning the nut by hand counterclockwise until it's tight should start turning the spindle, and through the drive system, the motor. If everything is free, you should be able to turn the motor with the QC nut. If you are not able to turn the motor by hand, then maybe you have a stuck brake or something else mechanically screwed up.
But first, I would disconnect power, pull the main fuses and check them with a meter. You could have a lost phase due to a blown fuse.
