Any CD motor should do, as long as you can attach to correct size
pulley to its shaft. You might have to construct a bracket that
attaches the motor to the sewing table, but that's a easy enough, or
it may simply be a bolt-in replacement for the AC motor.
Permanent magnet DC reversible motors are available all over, and you
just need to find one that meets the same RPM and HP ratings as the AC
motor, and that will mate with the drive belt pulley (or acquire a
another pulley of the same size that will mate with the new DC motor).
It's also nice if you can match the mounting hole configuration,
avoiding the need to build a custom bracket, or any additional hole
drilling.
Price ranges from $5-$500. It all depends on what you find when you
shop on the net. www.surpluscenter.com might be a good place to start
shopping, but lots of other places as well-- here is an example of a
motor that might work:
