For standing a DC motor a starter is required because
A. it limits the starting current to a safe value.
B. It starts the motor.
C. it limits the speed of the motor.
D. None of the above.
Answer: A
Share your understanding of this question with the correct explanation.
or starting a DC motor, a starter is required because it limits the starting current to a safe value.
When a DC motor is initially turned on, it experiences a high inrush current due to the low resistance of the armature winding. This high starting current can cause damage to the motor and other electrical components in the circuit.
A starter is used to control and limit the starting current of the DC motor. It typically includes various protective devices such as overload relays and contactors. These components help regulate the flow of current and protect the motor from excessive current draw.
By limiting the starting current to a safe value, the starter ensures the smooth and controlled starting of the motor, preventing damage to the motor windings and other electrical components.
Therefore, the correct answer is A: It limits the starting current to a safe value.
