AC Large Motor Maintenance
Course Content
EASA'S newest technical seminar covers horizontal and vertical squirrel cage induction motors in the 300 to 5,000 horsepower range, low and medium voltage. Many of the principles covered will apply to other sizes and technologies, as well. While the focus primarily is on motors built to NEMA standards, much of the material is also applicable to IEC motors. This seminar was produced by
Austin Bonnett, EASA's education and technology consultant.
