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.
What Do Participants Learn?
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
Who Should Attend?
