This, obviously, does not qualify as a standalone generator, since it

requires snigle phase input on L1-L2.



But can this motor somehow excite itself to generate electricity?

If you connect a internal combustion engine to a " phase converter " , and arrange the gearing between the phase converter and the engine so the engine puts power into the system, you will have a three phase generator. Could be useful if you wanted to run a honking big three phase welder and did not have an electric outlet that would provide enough power for the welder.
