If speed is decreased in a DC motor, what happens to the back end and armature current

Answers

Answered by SUMANTHTHEGREAT

In case of DC motor, the speed is proportional to the back emf (Ea ∝ N). So, with the increase in speed, the back emf also increases. Therefore, armature current is also decreased, in case of series motor, armature current is equal to the line or load current.
