1.Speed control of shunt motor
(a)Flux control method - By decreasing the flux, speed can be increased. Flux is controlled with the help of a rheostat.
(b)Armature control method - The voltage across the armature is adjusted by a variable rheostat.
(c)Voltage control method (Ward leonard system)
2.Speed control of series motor
(a)Flux control method
(b)Variable resistor method
