This trial-use guide contains instructions for conducting tests to determine the performance characteristics and machine parameters of permanent magnet (PM) machines. The tests described may be applied to motors and generators 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 this guide shall cover all possible tests, or tests of a research nature, but only those general methods that may be used to obtain the performance data and machine parameters. 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.
The term specified conditions for tests as used in this guide will be considered as rated conditions unless otherwise agreed upon. Rated conditions apply usually to the quantities listed on the machine nameplate.
Instructions for conducting tests to determine the performance characteristics and machine parameters of PM machines are covered in this guide. Additional tests can be required by the customers and operators to satisfy specific performance indices.
This guide consists of seven clauses. By tiillowing the IEEE 2012 style guide. the first three clauses are mandatory clauses for all new standards. Clause I gives an overview of the entire guide using the scope approved by the IEEE Standards Board. (‘lause 2 lists the normative references. (‘lause 3 includes the definitions. Clause 3 through Clause 6 arc written in two parts, by following the structure of IEEE Std 115TM)
Clause 3 through Clause S constitute Part I and describe the steady-state and transient performance test procedures. Clause 4 describes the condition and integrity tests, some of which may precede the performance testing described in Clause 5 and Clause 6. Many of these tests are performed to assess the overall health of the machine. Since the PM excitation is usually employed in the rotor, the stator construction is often similar to the stator of the wound-field synchronous machincs. Therefore, many statorspecific tests can be applied to PM machines by following IEEE Std 115. Clause 4 describes the steady- state performance tests. The term steady-state is defined for these tests in 4.5.1. Clause 5 describes the transient tests. These tests include retardation and sudden short-circuit tests.
Clause 6 constitutes Part II of the guide and describes the machine operating characteristics, such as losses, efficiency, thermal capability, torque-speed characteristics, and torque ripple. In the initial ballot, a Clause 8 was included to describe the test procedures for determination of model parameters. The Working Group decided not to include this clause for this ballot since there are many issues for different rotor configurations that have not been fully resolved to recommend the tests to the user. The publication of this guide should encourage users to contribute to the futurc revisions to resolve the testing issues for parameters in PM machines of various rotor configurations. References [B2], [B6], and [BX]3 can be used as the basis for the next revision.
Where the test procedure for a PM machine is the same as that for a wound-field synchronous machine, reference to the test procedure in IEEE Std 115 is provided in lieu of duplicating the same information in this guide. Consequently. the use of II’F.F. Std 115 in conjunction with this guide is recommended.IEEE 1812 pdf download.
