Contained in this trial-use guide are 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.

Diese Arbeit behandelt die Eisenverluste in permanentmagneterregten Synchronmaschinen und erarbeitet eine in der Ingenieurspraxis umsetzbare Simulationsmethodik, welche die praktische Charakterisierung weichmagnetischer Werkstoffe durch erweiterte Messmethoden mit Werkstoffmodellen zur numerischen Berechnung verknüpft. Des Weiteren stellt diese Arbeit eine neuartige Berechnungsmethode vor, um den Rechenaufwand der numerischen Berechnung zu reduzieren. This work contributes itself to modeling of magnetic core losses in permanent magnet synchronous machines and develops a simulation method for engineering practices. This method combines the practical characterization of soft magnetic materials and the material models for numerical finite element calculation by using extended measuring methods. Furthermore, this work presents a novel calculation method that reduces numerical simulation effort.

Die präzise Kraftstoffdosierung spielt bei der Benzin-Direkteinspritzung eine wesentliche Rolle im Hinblick auf Abgasemissionen und Verbrauch. Fertigungsbedingte Injektor-zu-Injektor-Streuungen und Bauteildriften müssen ausgeglichen werden. In dieser Arbeit wird ein neuartiges Kalibrierungsverfahren für Magnet-Injektoren vorgestellt, das den während der Kraftstoffeinspritzung emittierten Körperschall zur

This reprint is comprised of eleven articles that are screened by our hard-working peer reviewers. It mainly focuses on the recent advances in electric motors and drives, to adapt to the ongoing trends of electrification in both transportation and industry. New structural motors, such as the axial flux machine and the multi-phase machine, are introduced because of their enhanced reliability for use in next-generation electrified transportation. Special attention is also given to the micro PM motor, which has a broad use in many areas. In addition, advanced control techniques, such as position sensorless control and fault-tolerant control, are also incorporated to fulfill the demand for safe crucial applications, and the modeling of the bearing voltage and a line-start permanent magnet motor can be of particular interest to the industrial sectors. Through this reprint, we hope to provide a new perspective for the readers to manage their encountered problems, as well as stimulate innovative ideas for the electrified transportation of the next generation.
