Abstract :
The use of AC adjustable-speed drives for rolling mill applications is addressed. AC motor characteristics and how they relate to adjustable-speed mill drives are described. A review of AC motor theory highlighting distinctions between induction and synchronous machines along with comparisons to DC motor performance is included. Constant power speed range performance and limitations, damper winding requirements, and the selection of motor variables such as terminal voltage and frequency are discussed
