Answer Posted / sambhu chandran

because in 1 phase induction motor the flux produced is
alternating. so the net torque is zero ,for making it as uni
directinal we use several methods like phase splitting
method,capacitor start capacitor running,etc

if any house we instaled a 1.5 ton ac and its phase cable of wiring is installed but netrual cable of wiring not instaed. my question is that is neutual of house(for other wiring is capable for ac load or a sepeart neutrual wiring required
