Answer / ashok kumar

in DC motor speed control is very easy and for kiln
operation it required high starting torque , so we go for
dc motor but at the present scenerio we go for Ac motor
because initial cost of dc motor is very high and its
maintenance cost is also high.

Answer / saravanan

its because of High torque. but now a days AC motor is also
applicable for Kiln Drives

Answer / deepak gade

Hi

Kiln need high starting torque,and DC motor have capability
to produce high torque for kiln rotation

Also dc drive have speed accuracy, we can increse/decrese
speed upto 0.1 v dc

Answer / anam uddin

High Staring Torque & Speed Accuracy place an important role in kiln operation & DC drive can deliver both almost precisely so DC drive is preferred over others.

Answer / yaseen

dc drive is used for the following reasons
1 we need high torque.
2.we require speed.
3.ac can be used ,but there r some problems(due to high
cost)
4.cost of ac is more as rms is continues.
