Induction vs. synchronous motors — Different perspectives end user/motor manufacturer

This paper will review the many factors involved in the successful selection and operation of medium voltage (2300 V and above) induction and synchronous motors for use in the petrochemical industry. Among these are the power requirements of the driven load, start-up and normal operating conditions, and plant power restrictions. In addition, consideration must be given to maintenance requirements, necessary training and skills for site personnel, and the ability of the manufacturer to provide services to maximize the reliability of the machine. These areas will be discussed to give readers a better understanding of the subject, and field experiences from multiple petrochemical plants will be reviewed.
