Training course overview

Electric motors are important machines in all electrical installation. The types and operations of the motors have been carefully selected in order to optimize its utilization. In this Coventry Academy training course, different type of motors construction will be discussed so as to understand their operating principles and characteristics includes single phase motors, three phase motors and drives.

In the AC single phase and three phase motors the various types design criteria, enclosures and methods of starting will be discussed in depth, so as to comprehend its starting and operational functionalities. Electric motors being an integral component in electrical installation the protection methods and maintenance are also emphasized.

Understanding maintenance and troubleshooting procedures of motor means that reduced downtime and increased productivity are the immediate benefits for the company and its management. Equally important, the protection requirements incorporating digital numerical relays along with their function and integration with the overall system ensures that such expensive apparatus, requiring high capital investment, is well guarded against failures further offering safety for operations personnel as well.

This Coventry Academy training course will feature:

  • The operations and characteristics of single-phase motors
  • Characteristics and construction of three phase induction motors
  • Operation of variable frequency drive motors
  • The importance and role of motor protection and numerical relays
  • The types of maintenance strategies for motors installation
