Braking of DC Motors: Controlled slowing or stopping of a motor and its driven load is as important as starting in many applications (e.g. cranes, traction on a slope to…

Series Parallel Control of DC Motor: Series Parallel Control of DC Motor - Here two identical motors are coupled together mechanically to a common load. Two speeds at constant torque…

Starting of DC Motors: At the time of Starting of DC Motors (n = 0), the induced emf of a motor is zero such that the current drawn from rated…

Commutation in DC Machine or Generator or Motor: One coil each under an adjoining pole-pair is connected between adjacent commutator segments in a lap-wound dc armature, while in a wave-wound…

Compensating Winding in DC Machine: Compensating Winding in DC Machine - It was seen from earlier section, that armature reaction causes the flux density wave to be so badly distorted…
