Speed Control of DC Motor

DC Motor speed control means to have full control on the speed of DC Motor. The variation in speed of DC Motor because of variation in load is not the speed control. Therefore intentional variation in speed of DC Motor is called Speed Control. As...

DC Motor Starter

D. C Motor Starting: Why Starter Needed: Let Vt  = Terminal Voltage Ia = Armature Current ra = Armature Resistance Ea = Back emf = KaØWm At the time of starting, speed of motor is zero hence Wm = 0, therefore there will not be...
