Whenever a DC MOTOR starts, it poses unique challenges. The primary issue being the requirement of a starting current that is 5 to 6 times the load current. Such huge starting current can be damaging as it overheats the motor’s armature winding and results in a sudden voltage drop in the power supply.
Thus, it is essential to lower this starting current and a starter does exactly the same. It safeguards the motor’s circuit by working like a variable resistance in series with the armature circuit. In addition, it also reduces the load and torque of a motor when it starts. There are different types of starters namely 3 point starter, 4 point starter, no-load release coil starter, etc.
