Optimisation of Synchronous Reluctance Motors (SynchRels) using Opera

In the last few decades, the synchronous reluctance motor (SynchRel) has been relatively neglected in industrial, domestic and traction application because of the ascendency of permanent magnet (PM) and the ubiquitous induction (IM) motor. Recent vitality in rare earth PM prices and the unavoidable losses in IM’s have renewed interest in SynchRels – especially for [...] Posted in Motors,Synchronous Machines

Measurement, Simulation and Calculation Using Fourier Transformation of Iron Losses for Electrical Steel Sheets with Higher Frequency and Temperature Effects

Authors: N. Yogal, C. Lehrmann, M. Henke and H. Zheng Abstract: The losses present in electrical machines are of major concern in modern industrial applications, very high speed drives, aerospace applications and the automotive industry. This paper presents the magnetic characterization of non-oriented steel sheets used for manufacturing permanent magnet synchronous machines and synchronous reluctance machines when these […]

Topology comparison of ferrite magnet synchronous machines with consideration of low inertia

Authors: Christian Heister and Markus Henke Abstract: In order to replace rare-earth magnets five different machine topologies are considered, designed and studied in detail. With a synchronous reluctance machine (SRM) a machine without magnets is included in this comparison. The improvement by the insertion of cheap ferrite magnets in a SRM is studied by designing […]

Characterising lifecycle behaviour of permanent magnets is critical to emergent electrical machine applications

Permanent magnet materials are now being used in many designs of new electrical machine applications, and a lot of this equipment will be expected to have long lifecycles. If performance and lifecycle targets are to be met, then detailed characterisation at the design stage using advanced electromagnetic and multiphysics simulation technology will be critical, according […]

Simulation accuracy helps pioneering superconducting generator developments

Factory testing of a pioneering superconducting generator for hydroelectric applications from GE Power Conversion business has demonstrated a high correlation between the accuracy of the Opera electromagnetic simulation tool used during the design process, and the performance of the finished product. The proven fidelity of the simulation, for such a complex electrical machine with 28 […]
