Cobham Technical Services has released a new version of its Opera electromagnetics and multiphysics design software that enables design engineers to considerably accelerate analysis time. By harnessing the parallel processing capabilities of multi-core processors, computational time can be significantly reduced using Opera-3d version 16.
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 to Cobham Technical Services.
Benchmark demonstrates >98% accuracy of simulated vs real-world results.
Ideal design tool for electromagnetic components in many emergent applications including high efficiency motors and generators.
Innovative magnetically coupled flywheel could save ~10% of fuel.
The Opera electromagnetic design tool has helped to accelerate commercial development of a new generation of innovative high speed flywheel energy storage systems. Created by the technology development company Ricardo, the new energy storage systems are designed to reduce the fuel costs of hydraulically-powered construction equipment such as wheeled loaders and excavators. Thanks to the speed and flexibility of Opera software, Ricardo investigated and characterised over 100 different design concepts in just three months, before settling on the final design solution which employs magnetic coupling to rotate a composite flywheel at around 45,000 RPM.
From superconducting magnets for particle research to a spectrum of applications – the Opera software package marches on!
Coinciding with Cobham’s 80th anniversary celebrations, the developers of the renowned Opera electromagnetic simulation software are celebrating the 30th anniversary of the Vector Fields Software business unit. Initially focused on making the design of particle accelerator magnets practical, their software tools remain at the leading edge of electromagnetic design today. This success is in large part due to continuing development of the founders’ pioneering ideas for numerical software – which made possible the first practical commercial solution for solving complex and three-dimensional electromagnetic simulations.
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 poles, could help GE to create advanced solutions for numerous emergent superconducting applications in markets such as wind, wave and hydroelectric power generation, and electric motors for ship propulsion.

Cobham Technical Services has extended the multiphysics capabilities of the well-known Opera-3D finite element software for electromagnetic design with a new solver that can be used to analyse natural vibration modes. The tool is expected to prove particularly useful for electrical machine developers, who can employ it to investigate and minimise forces that might cause oscillations close to the natural frequencies of the equipment and thereby avoid excessive vibration or collisions between rotating and stationary parts.
Radical new design aims to deliver a 20% reduction in the cost of wind generated electricity
Cobham Technical Services is helping Colorado-based Boulder Wind Power (BWP) accelerate development of a radical new permanent magnet generator through use of advanced electromagnetic design software. Based on a permanent magnet, direct drive design, BWP’s generator uses a unique axial flux, air-core architecture that increases efficiency and reliability, and will ultimately reduce the cost of wind generated electricity to compete at parity with fossil fuels.

A new web-based technical presentation from Cobham Technical Services helps designers of electric motors and generators use finite element analysis (FEA) techniques to accelerate product development and improve design accuracy. The presentation will also be of interest to electromagnetic and electromechanical analysts, as well as engineers who are currently using analytical design packages for rotating machines. First shown live to a pre-registered audience as a webinar, the 47-minute audio/visual presentation is now available – in English and French – for on-demand playback via Cobham’s dedicated motor design software website: http://www.motor-design-software.com.
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.
