Kiln drives are used in rotary kilns, typically found in cement plants, where they rotate the kiln for uniform heating of materials. The primary requirements for these drives are:
- High starting torque to overcome the kiln's inertia.
- Smooth speed control to maintain process efficiency.
- Reliability and durability in harsh environments.
Synchronous motors are not suitable for kiln drives as kiln drives need variable speed control where whereas synchronous motors run at a constant speed.
Synchronous motors have poor starting torque. They are not self-starting motors.
