Testing of large motors to API 541 and API 546 standards

A summary of test requirements for testing large AC induction and synchronous motors to API 541 and API 546 specifications is provided. An overview of testing facilities and methods necessary to address these requirements is given. Testing of special-purpose motors requiring more stringent tests is specifically addressed. The additional test requirements specified by the API standards, especially with regard to balance and vibration are examined. In order to satisfactorily test large machines to the present and forecast needs of the petroleum industry, a test facility with a capacity of approximately 50 MVA is assumed.<<ETX>>
