Kavo spindle inverter

Would anyone know of an inverter circuit that i could cobble together for a
50000 rpm Kavo spindle model # 4050, it's specs are 24Volt, 100 watts, 83 to
833 hz, field windings are delta and .5 ohms DC each and it is an induction
motor as opposed to permanent magnet. I have a Kavo type 4444 inverter but
it's not a good match for this spindle if anyone is interested in buying it.
Thanks, Denis
