Ward Leonard Speed Control Overview by mansoor.ahmed100 is a document available to read on EtoBox.
The Ward-Leonard speed control system uses an AC motor to drive two DC generators. One generator provides a constant voltage to the field winding of the other generator, whose output voltage can be varied to control the speed of a DC motor. This allows wide and sensitive speed control but requires three machines. DC motor braking techniques include plugging, rheostatic braking, and regenerative braking. Plugging reverses motor connections to produce braking torque. Rheostatic braking dissipates energy in
