    If "only half the power" would be fine for you, then there's maybe an easy option. Use a 230V:115V stepdown transformer/rectifier/smoothing cap for the field winding, and a PWM regulator run off rectified 230V AC for the armature - last time i looked for one these they were available as an off the shelf module from a few suppliers. This will only give you 325V tops on the armature but hey that's still 4000...4500 rpm and at least 75% power.
