I would swap the motor out for a DC type and use a simple analogue servo.
AC motors have to be manufactured to operate at variable speed from new otherwise they are likely to produce poor torque or overheat. The AC machines that many of us pick up for home use were built from new for production use and the fiddly speed changing was only ever carried out between production batches.
It is not going to be easy.
