I'm not sure about yours, but on mine, the motor that turns the bowl,,,yeah, a separate one,, burned up after about a month of use.
After hours on the net, trying to find the replacement parts site for kitchenaid, I finally found it,, and the part number,, only to be informed that the part was obsolete.
By the way,,, the same mixer is still being sold.
Some parts are available, but remember,, it's made in China, so the parts may be hard to get shipped correctly.
Good luck,
