Les concepteurs des machines électriques tournantes d’aujourd’hui sont l’objet de pressions pour offrir des moteurs plus efficaces, robustes et innovants et dans des délais toujours plus courts. Au cours de ce webinaire Cobham Technical Services – Vector Fields Software montrera comment la Suite Opera peut être mise à profit pour apporter l’exactitude de l’analyse par éléments finis (FEA) avec la facilité d’utilisation des logiciels de conception analytique.
Next-generation electric motors for low carbon emission vehicles are the target of a new collaborative research programme to be led by Cobham Technical Services. The project, ‘Rapid Design and Development of a Switched Reluctance Traction Motor’, will also involve partners Jaguar Land-Rover and engineering consultancy Ricardo UK, and is co-funded by the Technology Strategy Board.
As part of its work in the project, Cobham will develop multi-physics software and capture the other partners’ methodology in order to design, simulate and analyse the performance of high efficiency, lightweight electric traction motors that eliminate the use of expensive magnetic materials. Using these new software tools JLR and Ricardo will design and manufacture a prototype switched reluctance motor that addresses the requirements of luxury hybrid vehicles.

Cobham Technical Services – Vector Fields Software and its product Opera have been at the forefront of finite element electromagnetic analysis for more than twenty-five years.
Opera is a general-purpose finite element software suite for the design and optimization of electromagnetic devices in two or three space dimensions. The software has been in continuous development since 1984, and its accuracy and capabilities for multiphysics analysis has made it a firm favourite in both scientific and industrial communities. The ability to couple electromagnetic analysis to built-in thermal and stress solutions, along with drive circuits, mechanical drives and system representations allows in-depth analysis. Remove assumptions and bottlenecks from your design process and deliver right-first-time products.

Cobham Technical Services is launching a 3D version of its rapid electromagnetic design tool for rotating electrical machines – the Advanced Machines Environment. The new software combines the extreme accuracy of finite-element analysis (FEA) simulation with a design entry system that creates full 3D models of electric motors or generators within minutes.
provides ultra-fast design entry for powerful FEA electromagnetic simulation
At CWIEME, Cobham Technical Services is releasing a new version of its Vector Fields Software tool for designing rotating electrical machinery. The electromagnetic simulation software combines the accuracy of virtual prototyping using finite-element analysis with a rapid front-end design tool that allows users to create models of motors and generators in minutes — allowing users to achieve radical new levels of development productivity.
Vector Fields, a part of Cobham plc, has extended the accuracy of its Opera electromagnetic simulator for electrical machinery applications with a new finite-element hysteresis solver for soft magnetic materials. Believed to be unique, the new Hysteresis Solver provides designers of motors, generators and other electrical machinery with an accurate means of accounting for losses and predicting performance changes due to hysteresis effects in the specialty electrical steels that are increasingly being used to enhance machine efficiency.
