Chat Online· An induction motor is similar to a poly-phase transformer whose secondary is short circuited. Thus at normal supply voltage like in transformers the initial current taken by the primary is very large for a short while. Unlike in DC motors large current at starting is due to the absence of back emf.If an induction motor is directly switched on from the supply it takes 5 to 7 times its full
Chat OnlineEssential and Need of Starter with Motor. Motors below 1 HP (0.7457) is directly connected to the power supply without starter because their armature resistance is very high and they have the ability to afford and pass higher current due to high resistance. So the armature windings are safe from the high starting current while staring a motor.
