Description

Revision Standard – Active. Instructions for conducting tests to determine the performance characteristics of permanent magnet (PM) machines are contained in this guide. Motors and generators may have the described tests applied as needed, and no attempt is made to partition this guide into clauses applying to motors and clauses applying to generators. It is not intended that all possible tests, or tests of a research nature, shall be covered by this guide but only those general methods that may be used to obtain the performance data. The schedule of factory and field tests, which may be required on new equipment, is normally specified by applicable standards or by contract specifications. This guide should not be interpreted as requiring any specific test in a given transaction or implying any guarantee as to specific performance indices or operating conditions.
