Electrical Motors & Variable Speed Drives Masterclass



Introduction:


The various drive features such as operating modes, braking types, automatic restart and many others will be discussed in detail. You will learn the four basic requirements for a VSD to function properly with emphasis on typical controller faults, their causes and how they can be repaired. The concluding section of the course gives you the fundamental tools in troubleshooting VSDs confidently and effectively.

 

The course covers all topics relating to both AC motors and their drives. AC motors represent 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 a requirement along with their function and integration with the overall system ensures that such expensive apparatus is well guarded against failures which further offer safety for operations personnel as well. This course will feature:

 

  • Understanding types of AC motors and their starting methods
  • Principle of operation of variable speed drives
  • Identification of the various types of variable speed drive
  • Trouble shooting and maintenance of variable speed drives
  • Protection of motors and drives

Course Objectives:


By the end of this course, delegates will be able to:

 

  • 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
