generate 3 phase delta?

I have a small ac motor.. I looked up the part number... globe
75a120-2.. 3 wires... data*** says its a delta connection. I'd like
to understand how to drive this thing... seems like it would be simpler
if it had 4 wires and was connected wye.... but its not, so here I am
asking for ideas. I guess I need 3 'power amps' that will put out 3
phase sin waves. I guess the clever part is generating 4 or 5 bit sin
waves using pwm? I guess this is just like a synchro... will work at
10hz or 1hz or .1hz? The magnet just follows the field around?
