About the program
"Principles of Medium and Large AC Motors" is highly rated by attendees. The seminar and its companion second edition manual, was originally produced by Austin Bonnett, EASA's education and technology consultant, in collaboration with EASA's Technical Support Specialists.

While the course covers horizontal and vertical squirrel-cage induction motors in the 300 to 5,000 horsepower range, low- and medium-voltage, most of the principles covered apply to other sizes as well. This manual focuses primarily on NEMA motors.

Seminar highlights include:

• Motor nomenclature & definitions
• Motor enclosures
• Typical motor applications
• Safety & handling considerations
