Publication date: 
August 2015
Type of media: 
Book

This valuable instructional/resource manual is available in printed, downloadable and CD-ROM versions.

For this second edition, the manual has been reorganized, updated with new information, including revised standards and published articles, and edited extensively. The manual includes drawings, photos and extensive text and documentation on AC motors, including how they work, specific information on enclosures, construction of components and applications. Many of the principles included apply to all AC motors, especially those with accessories that were associated with larger machines in the past (such as encoders, RTDs, thermostats, space heaters, vibration sensors, etc.).

While the manual 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.

Sections in the manual include:

  • Motor nomenclature & definitions
  • Motor enclosures
  • Typical motor applications
  • Safety & handling considerations
  • Basic motor theory
  • Motor standards
  • Stators
  • Squirrel cage rotors
  • Shafts
  • Bearings & lubrication
  • Motor accessories & terminal boxes
  • Test & inspection procedures
  • Motor alignment, vibration & noise
  • Storage procedures
  • Synchronous machines
