Another approach would be to use a single to three phase converter to convert the genset output to three phase, changing the shaft generator stator wires to three phase and then feeding the shaft generator the three phase out of the converter to make a nicely rotating field in the shaft generator. Then fire up the rotor current.
The shaft generator is essentially a three phase machine I have hooked up as a single phase.
