Question moved from Cars and Trucks.
Stand Mixers don't normally have belts and I don't believe this one does as I can't find spare belts. They are operated by nylon cogs that run in grease. The most likely reason is the she shear pin has sheared. This is a small pin like a nail that goes through a cog or shaft and shears if too much load is put on the mixer beater or dough hook. It often happens if you make bread and have the speed too high.
