Ahhh. It's a synchronous motor, so it not only wants AC, but it wants AC at 50/60 Hz and it probably wants at least a modest approximation of a sine wave. A square wave will probably make it unhappy...

Is efficiency a big issue? Gonna plug it into the wall, or run it off a battery?

If efficiency isn't really an issue, then a hardware solution with an op-amp based sinewave generator feeding an audio amplifier type driver is probably easiest.
