Answer / erharisheee51

BY CONTROLING THE VOLTAGE , WE CAN CONTROL THE SPEED OF THE
MOTOR.

Answer / 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.

if power factor comes in leading & showing -0.95. Is there any effect on electrical system? if yes, then please tell me what would be the effects. & how long we keep power factor in leading. Keeping power factor in leading shows more KW & less KVA is it correct or not.
