Testing of advanced permanent magnet machines for a wide range of applications

Permanent magnet machines are widely used across a wide range of applications. One of the key challenges is that there are no well-established standards for testing PM machines similar to those used for testing induction machines and wound-field synchronous machines. This paper will provide an overview of the key tests that need to be performed in order to fully quantify the PM machine performance. The paper also provides an overview of three distinct applications of advanced permanent magnet machine technologies. It describes the specific application benefits that are accomplished with permanent magnet solutions for automotive, and Oil & Gas. The details of the technology development for these three first-of-a-kind machines have been previously presented in other publications showing that each of which advances the state of the art in power density, torque density, or speed. The focus of this paper is the various tests that were performed on each of these machines as well as the test results.
