Hi Everybody.
I heard that the speed of the DC motor can be controlled by sensing the back EMF of the motor. I read one article in EDN about it. The author sensed current through armature and used it
as a feedback for speed control.
But I know that current through the armature represents the torque not speed. And from 0 to rated motor speed torque supplied by the motor is same.
Can somebody help me clear confusion.
Thanks.
Vikas.
