Yes, as armine said that there is a diffrent method for
starting both the motores in single phase more it can be
driven as capacitor start, capccitor run ,also capacitor
start capacitor run motor.
Considering a three phase motor when three phase supply is
given to the startor winding rotating magnatic field is
developed which rotaes with syschronous speed ( NS =
120F/P ). now this magnatic field is connected to rotar bar
& as the rotar winding is shot ( in case of Squrell cage
rotor through copper ring & in case of sleepring rotor
through resistence ) so the current flows in rotor bar .
now as this in magnatic field . the force is applied on the
rotor . rotor start moving & as the magnatic field is
rotating rotor keep moving but is legs behind a bit then a
synchronous speed & this phenomina called a Slip.
please revert if any querry exists.
