How Does DC Motor Start?
DC motors have specific starting characteristics due to the low resistance and inductance of the armature circuit coupled with rotor mechanical inertia. Upon switching on, the initial armature speed and corresponding back electromotive force are minimal, leading to a surge in starting current, which can be 15-20 times the rated current. This can cause grid interference, machinery impact, and commutator sparking.
To mitigate this, a variable resistor can be connected in series within the armature circuit, gradually decreasing resistance as the motor starts. This method, known as series resistance starting, limits the starting current to a permissible value. While it's effective for small and medium-sized DC motors, it's not ideal for conventional or larger motors due to its high energy consumption. However, certain applications, like frequent tram startups in large cities, employ this method for its simplicity and efficiency.
