Answer / saravanan

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

Answer / deepak gade

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
