Answer / vishv shah

sry...for that wrong ans.......for
low voltage(1 phase - 230 volt)
operation! IM needs some mechanical
machine to start the motor but while
in high voltage(3 phase - 440 volt)
their is no any requirement like in
low voltage.....so........because
in high voltage rmf is generate to
start the motor

Answer / vishv shah

as u know that IM run only because
of rmf .....rmf is produce because
of 120degree phase difference
between r;y;b......in 1phase i.e at
230volt no rmf is generate so.....!
IM can't run.......
