Remember though, the electric cars have motors in the class we are
talking about and they are not anywhere near that size.  So it can
be done.  Also That motor is probably made to sustain that 40 hp
without problems for years on continous running, so if someone
was willing to have a shorter lifetime it would be able to be
a smaller motor.  I have seen a fire pump motor about the same size
you are describing running three-phase and putting out more like
140 hp.  So I think it has something to do with how long you
want it to last.
