Sl-bd22 motor I took out the motor and its making a grinding sound and spinning at various speeds.

That is an older turntable and may require a "phono" input (a designated input--not just an RCA phono plug).  Newer stereo systems may not have a phono input and you may have to feed the turntable through a pre-amplifier to get enough power to run it with a standard component line input (like Tape or Aux).

SOURCE: Technics SL-BD22 ground wire does not reduce hum. Any solutions?

I have found out that the female phono plugs on the turntable are sensative and have to have a solid connection and often adjusted from time to time to eliminate the 60 cycle hum.

First check the belt it could be causing the problem (I assuming it's a belt drive as it looks like one). Next check for obstructions. If you lift of the matt you should get a view inside. Apply Silcone Grease to the spindle area. If still no luck, remove the bottom cover to gain a better view and see what's what. Again if you think it needs a touch of grease then apply it.

Your turntable is probably belt driven so most likely motor is turning okay but belt is slipping.
They are easy to change, first just lift rubber mat on platter and you should be able to see the belt through a access hole in the platter.
