Where can i find a belt for my necchi model 534FB

Question edited for clarity and all the typos.
Question moved from Televisions to make model category.

The whirling noise is the motor. It may be that the drive belt has broken?

When was the last time it was professionally cleaned, serviced and timed? With moderate use, they need doing every 2 to 3 years. The inside workings of sewing machines are very tough and seldom 'break'.

The is usually an adjustment to tighten the belts by moving the motor. There are other ideas here, clutch, the knob in the handwheel or the screw in the needle bar..

Hm, I'm not able to locate a manual but may be able to offer some suggestions.

Remove the top thread from the machine.
AVOID OLD OR BARGAIN BIN THREAD!
Use the same thread in top and bobbin.
Be sure to use a brand new needle--needs to be compatible with the thread and fabric of the project..
ALWAYS RAISE the presser foot and rethread from the beginning.
Set the top tension to the midway point.
Verify the bobbin is loaded and threaded correctly and it turns the correct direction.
Pull the bobbin thread up through the fabric before taking the first stitch. It also helps to hold both thread tails in your left hand when taking the first stitches.
Test your machine and tweak the top tension until the top and bobbin threads meet in the middle of the fabric. (Increased top tension will pull the bobbin thread up. Decreased top tension will allow the bobbin thread to pull the top thread down.)

Is the bobbin wheel actually turning? If so, the bobbin winder is still activated. Have you tried turning the inner wheel on the handwheel to de-activate the bobbin (see video)?

If that doesn't help, you may need to take the machine for service.
