Answer Posted / soutrick chakraborty
we can control the speed of the dc shunt motor by two
methods. but at first we should know there are two type
speed, 1> base speed 2> top speed. for reach the base speed
we increase the armature voltage maximum , which is
mentioned in motor nameplate. and reach the top speed we
should decrease the feild flux, it means feild current,
which is also mentioned in motor name plate.
