what is the differance between ac induction motor and ac
synchronous motor?

Answer Posted / safeerudeen

Induction motor is the cheapest of all motors,which runs at
a speed less than synchronous speed.Induction motor works on
the principle of Faraday's laws of electromagnetic induction

synchronous motor which runs at synchronous speed, which is
costlier than induction motor,synchronous motor is not self
starting but induction motor is self sarting

ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]
