'Application of AC motors and drives in steel
At many places, the type and configuration of electric drives need to be reviewed keeping in view the recent developments in the area and improvements in similar applications in other industries.Mill Drives: Requirements of mill drives are: High starting torque. The starting current must be limited to a maximum of two times the full load value to minimize voltage dips. An overload capacity of 50% for 1 min occurring for 4 times an hour. f Three starts from cold conditions and two consecutive starts from hot.Cement Mill Drives PDF Transmission (Mechanics) Engines

Electric Drive Block Diagram, Types and Applications ElProCus
Classification of Electrical Drives. Usually, these are classified into three types such as group drive, individual drive, and multi-motor drive. Additionally, these drives are further categorized based on the different parameters which are discussed below. Electrical Drives are classified into two types based on supply namely AC drives & DCPower requirement is very high. Speed control ratio is 1:10. Very low creeping speeds of 1 rpm may be required. Starting torque should be in the range 200 to 250% of full load torque. The acceleration of the drive should be completed in about 15 s. For small periods an overload capacity of 200-250% may be required.Cement Mill Process Requirement of Mill Motors Kiln Drives

Drive selection for rolling mills Russula
Rolling mill DC motors are best at low speed, high torque applications, while AC motors typically need to run above 800rpm to be cost effective. Also the case for higher efficiency of AC motors is many times negated by the wasteful braking methods of some AC drive systems. All this being said, for motors below 200-300kW, or when new The Siemens Drive Technologies Division has developed a new drive system for a cement mill as part of a joint project with Gebr. Pfeiffer SE. With an overall power rating of 11,500 kW and producing 450 metric tph of cement, the vertical mill is the most powerful of its kind in the world today.Siemens Multi-Drive System Powers Holcim Mill Cement Products
