Why We Need to Install a Starter with a Motor? Electrical ...

Essential 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.

liquid starter used for mill motor - kloofcpf.co.za
