Rotary three phase converters

[Mark Harriss]

Anyone know of any good books or websites on building a rotary three phase
converter suited to Australian conditions?. Most American designs use 220V
which is
two active wires taken from the pole transformer with neutral being the
center tap
if I understand it correctly.

It would be possible to build an exact cop of a yank design and feed it
240V
single phase but the way they are wired means you'd be connecting neutral
to one of
the motor phases: http://www.metalwebnews.com/howto/ph-conv/fig1.html

My motor is a multivoltage motor so it can run off 240V three phase
instead
of 415 Volts.

It might be worth looking through the archives of, or asking at
