Starting Requirements and Effects of Large Synchronous Motors

Modem cement plants require an ever increasing sensitivity toward the application of large synchronous motors. Choosing the correct drive, based on load requirements, necessitates a thorough investigation of power availability and its effect on starting, acceleration, and pull-in characteristics of the motor. Also of concern is how these characteristics can be altered by design; or by the installation of auxiliary equipment, which may improve conditions not totally possible by design alone.
