3 phase induction motor:
v giv 3phase supply to 3 phase stator winding, rotating
magnetic field running at synchronus speed is
produced.initially rotor is at standstill position (@ zero
rpm).this rotating magnetic field vil sweep over rotor.
thus there is cutting of flux lines. an emf is induced.
bcoz of this emf,a current is induced.now A CURRENT
CARRYING CONDUCTOR PLACED IN A MAGNETIC FIELD PRODUCES A
TORQUE.thus motor runs.

As we use capacitior bank in 3ph ckt for improvement of PF, why not we use capacitor in single phase domestric use, at our house their are many inductive equipments,like fan,mixer,tube choke,air conditioner they also draw PF... by using capacitor can they improve PF. if yes--what are advantage and how to connect a capactor in single ph,and which type of capacitor if no- what are disadvantages.
