Answer Posted / umang
in case of SQ motors, the rotors are shorted and in case of
slip ring motors the exterrnal resistance added with rotor
ckt. to get high starting torque along with limiting
starting current.So when the rotor achieves its full speed
hthe resistaces are shorted by slip rings.which help to get
high stating torque.

As we use capacitor bank in 3ph ckt to improve PF, can we use capacitor in single ph domestric use, in house we have Fan,Mixer,electric cooker,iron,tube choke they also lag the system,because it is inductive load. if it is possible to improve PF of single ph system-- if yes- type of capacitor to be used,connection diagram, working in detail. if no-- list it.
