One can use a Variac as a variable inductor, with a motor run cap, to vary the phase of a sync motor. John Freau pioneered this and is described on his web site: http://members.aol.com/futuret/page3.html
But I would first ask - are you really using a 2 HP motor? With what size power supply on your coil? 2HP to essentially turn a switch off and on seems a gross waste of power.
