Answer Posted / trupti
slip=(Ns-N)/Ns
wh Ns - sync speed
N - actual speed of rotor.
generally whn IM is acting as motor,rotor speed is always
less than Ns,but if it is acting as gen(a prime mover moves
rotor),N bcms gr8er than Ns.
hence 4m formula we can c that s bcms -ve.
it implies rotor is running faster than stator field.

generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
