Acceptance testing of electric motors and generators

A comprehensive inspection and acceptance test program for electric motors and generators is outlined. Recommended electrical and mechanical inspections and tests are described, and bearing housing and shaft vibration limits are recommended for all types of electric machines. The mechanical test procedures and vibration limits as described are proposed for inclusion in future editions of IEEE and NEMA standards. An inspection and test matrix for highly critical special-purpose and less critical general-purpose machines is given.<<ETX>>
