Acceptance testing of electric motors and generators

A comprehensive inspection and acceptance-test program for electric motors and generators of 300 HP (225 kW) and larger is outlined. Induction and synchronous machines are included, and references are made to IEEE, ANSI, and NEMA standards for the electrical tests. 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 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
