Speed control methods of DC motor | electricaleasy

Speed control methods of DC motor | electricaleasy

Speed of a dc motor is directly proportional to the back emf E b and E b = V - I a R a.That means, when supply voltage V and the armature resistance R a are kept constant, then the speed is directly proportional to armature current I a.Thus, if we add resistance in series with the armature, I a decreases and, hence, the speed also decreases. Greater the resistance in series with the armature .

FAQ: What are DC shunt motors and where are they used?

Dec 29, 2015 · Therefore, the starting torque of a DC shunt motor is low, meaning that the shaft load must be small at startup. In a DC shunt motor, torque is proportional to armature current (as shown in the torque equation below). In contrast, for a series-wound DC motor, torque increases as the square of armature current.
