in 1 phase i.m the stator is distributed wdg. & squirrel
cage rotor.When it is fed from 1 phase supply the sator
wdg. produces flux which is alternating i.e. alternates
along one space axis only.it is not synchronously revolving
flux as in case of 2 or 3 phase wdg.fed from 2 or 3 phase
supply.this pulsating flux acting on stationary squirrel
cage rotor can not produce rotation(remember:only revolving
flux can)so....it made self start by means of capacitor
with 90 phase split.ok.bye
