whye the current increases in the motor when the load on the
motor increases
Answer Posted / s s nanal
Full load speed of Induction Motor is near the sunchronous
speed. (Ns = 120 f/P) With increase in load the motor slows
down.Hence back emf developed also reduces.Hence motor
draws more current from supply in order to retain its speed
near synchronous speed.

1) why a dg set shows variation of power factor and load when synchronised with other dgs? 2)Why the load sharing is not become equal in all dgs?. 3)When a dg set will not run on auto start?
At the starting of dc motor and syn.motor and induction motor high current flowing through the winding. Due to this the windings burnt out. To avoid this different types of starters are used. But incase of transformer what Will be used (At starting no emf is induced in the primary winding)?
