Course Introduction

The course covers all topics relating to both AC motors and their drives. AC motors represent the industry's workhorse in all applications. It is no exaggeration to suggest that more than half of the energy consumed worldwide is converted by AC motors into work, and these are controlled by drives.
 

Understanding maintenance and troubleshooting procedures of such vital industrial equipment means that reduced downtime and increased productivity for the company. The protection is a requirement along with their function and integration with the overall system, ensuring that such expensive apparatus is well guarded against failures, which further offers safety for operations personnel as well.


Course objective

  • Understand the various types of AC motors and starters
  • Determine the components and operations of variable speed drives
  • Explain the different types of variable speed drives
  • Analyze the common faults in a variable-speed drive
  • Design the protection requirements for motors and drives
