WebJun 21, 2002 · Torque sharing between drives is coordinated through a dedicated communication link. The benefits of the conversion were impressive. Starting torque was … Webmotor. This must have high starting torque in order to start the kiln with a large eccentric load. A 6 x 60 m kiln requires around 800 kW to turn at 3 rpm. The speed of material flow through the kiln is proportional to rotation speed, and so a variable speed drive is needed in order to control this.
