Induction motors drive a variety of applications in a cement manufacturing plant such as kilns, crushers, ID fans, separators, cooler fans etc. Motor manufacturers serving cement industry needs are often faced with challenging tasks of designing motors suitable for various operating conditions and requirements which have to be not only reliable, but also cost competitive. During starting, several transient thermal and mechanical forces arise in a squirrel cage induction motor. Transient stresses due to starting, thermal and mechanical forces severely impact the overall life of the induction motor. The nature and effects of these forces and stresses are discussed.
