what is the difference between induction and synchronous
motor?explain in simple words?why 3 phase motor is given
preference over single phase motor.
Answer Posted / hrishikesh
main difference is that why IM doesnt run at synchronous speed?
coz of the slip.
ns= 120F/P
slip=(ns-1)/ns at synchronous speed
at standstill condition slip (%)will be 1
so as the slip increases speed of the motor decreases.
slip in the case of IM at standstill condition is 1. so
obiviously IM wont run at synchronous speed.
