Applications of Synchronous Motors. usually, synchronous motors are used for applications where precise and constant speed is required. Low power applications of these motors include positioning machines. These are also applied in robot actuators. Ball mills, clocks, record player turntables also make use of synchronous motors.

Variable speed drive technology and the importance of controlling the speed of existing motors have fascinated many attentions in the last years with the advent of new power devices and magnetic materials. This paper is a comprehensive review on applications of VSD in electrical motors energy savings.

With a power rating of up to greater than 100 MW (or torques up to greater than 40,000 kNm), the specialized high voltage motors are designed to suit the specific requirements of a complex application or to maximize the performance and implementation with an application drive system concept.

The ripple content in the armature current and possi­ble discontinuous conduction further affect the commutating capability of the motor. Therefore for power ratings beyond this value, ac drives are suitable. Tubular mills for Cement Mill Process are very slow speed high power loads.
