Answer / baskaran.r

single phase motors are not self starting as stated. hence
they are fitted with starting device like capacitors,
inductors,shaded pole etc. the capacitors are provided to
split the single phase in to two phases with an angle of
about 90 degrees. if we can use two phases without the
capacitor the motor can be used, provided the motor winding
is rated for 440 volts or line to line voltage

Answer / pratheesh

No need to explain....2 phase motor are similar to
single phase motors in working. Those are self starting
like single phase motors.
