I had a very similar problem with a Brent CXC I had just purchased for my wife. At low speeds, the motor made a horrible grinding sound and was jerky at best. I took the whole thing apart (including the motor) to find that the control and pedal where fine, but one of the magnets on the motor had seperated.
Now, for me, I was able to fix it by re-epoxying the magnet back in place and replacing the brushes and bearings (the last two were done because the wheel hadn't been used in 10 years, and the brushes were stuck/damaged and the bearings where making some noise).
Complications from magnet seperation could be costly; if the magnet is damaged, it has to be replaced, or if fragments nick the armature wiringing, it could cause a short. Either case, repair doesn't seem like a bad option depending on the motor. The 1HP motor that I had cost around 450$ from the original manufacture, but I believe Brent sold newer ones (different manufacture) for 350$. If it only cost 150$ to get the magnet re-epoxyed and armature rewrapped, then I would choose that as you basically have a new motor after all the work is done. In my case, it only cost me 20$ for brushes, 15$ for bearings, and a small amount of expoyed and time.

Margaret any electrician should be able to test the motor and controls to
see if there is a lose wire or if something is fried.
I have a number of Ceramic Monthlys, Clay Times, and Potters Illustrated you
are welcome to have. I live between Bennettsville and Dillon.
