Of course, the motor above will do - but one can get old
washing-machine motors for free (or nearly free) and they
do have variable-speed drivers as the washing machine has to
do several angular speeds.. The one I have even has the
ability that it will first turn a while (seconds) at low speed and
after that switch to full set speed..

One might even get quite good set-up by using the skeleton of
the washing-machine as well and replace the drum with spark-gap
set-up.. :)
