Is it an older mechanical machine (not computerized)? Bet it needs a good oiling. Old oil will dry out and turn to glue/varnish and actually prevents parts from moving and dragging on the motor. Use only fresh good quality sewing machine oil or Tri-Flow Synthetic Lube. Open the top, left side, and bottom of the machine. Slightly rock the handwheel and apply 1-2 drops of oil every place metal rubs on metal. Do NOT oil rubber, leather, or synthetic/nylon parts.
If it is still sluggish, you can direct hot air from a handheld hairdryer into the interior mechanics of the machine to help loosen things.
Older machines do need frequent oiling--ie, every time a new sewing project is begun or every six months if not in use. If a large project like a quilt, more frequent oiling may be needed. When you become familiar with the pleasing sound of a well-running machine, you will recognize when it needs some TLC.
