what is synchronous speed.? if an induction motor is made
to run at full load, then is this synch. speed too..?
Answer Posted / varun
the machine whose rotor's speed is equal to the speed of
rotation of stator's magnetic field, is called a synch.
motor,,,thus corresponding is the speed.
in an induction motor...
Nr=Ns(1-s)
Nr=speed of rotor
Ns=synchronous speed
s=slip
in synchronous motor s=0.

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.
