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.
