If it's really the spindle motor, they can often be fixed. The fault is very often some carbon accumulated at the brushes, shorts out or opens up. There are usually little slits at the bottom of the motor. One uses an electronic cleaner - lubricant with a plastic extender, spray into the motor, aiming at the brushes, and rotate the motor. Use a compressor to blow out the excess. Might take several tries, or if the brushes are actually damaged, then it wouldn't really work at all, of course.

One can use a small variable power supply to run the motor while spraying stuff in there. Be certain that you get the motor running in the correct direction, which would be clockwise as viewed from the top of the motor. This is because some motors are so CHEAP that the brush feeler barely extends beyond it's contact point. Running in reverse runs the risk that the end of the brush will catch on the commutator slits as it rotates, damaging the brush feeler.

P.S.

Best not to remove the motor from it's subchassis. The motor platter height is very critical.
