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 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.

Stress Analysis Software Helps Engineers Evaluate the Effect of Forces in Electrical Devices

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.

Cobham Technical Services and Boulder Wind Power collaborate to accelerate development of revolutionary wind turbine technology

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.

On-Demand Presentation Demystifies use of FEA for Motor and Generator Design

Available in English and French

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.

Research programme targets next-generation electric motors for luxury automobiles

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.

Advanced simulator speeds implementation of direct-drive electric motors in new automotive, marine and powergen applications

An innovative electromagnetic simulation tool is speeding the commercialization of a breakthrough direct-drive technology for electric vehicles by Magnomatics. The Opera simulator has been used by Magnomatics – a company that was set up to develop new forms of magnetic power transmission – to design a novel direct drive system that integrates a permanent magnet motor with non-contact magnetic gearing.

Called the Pseudo Direct Drive, this new form of traction motor offers such an exceptional torque density that it can even be packaged within a vehicle’s wheel. The technology has already been demonstrated on a 22-inch city-bus wheel where it generated a continuous rated torque of 4000 Nm and speeds of up to 750 RPM – which equates to a top speed of around 80 km/hour. Magnomatics is now engaged in several other Pseudo Direct Drive design projects in areas including marine propulsion, defence vehicles and direct-drive electricity generators for wind turbines.

Innovative electromagnetic design tool provides short route to motor perfection

Optimal design solutions to rotating electrical machine requirements can now be created in hours, by non specialists, using a new version of design automation software from Cobham Technical Services.

Cobham’s Machines Environment introduced a new level of user friendliness when it was launched by providing a design entry system that allows precision finite-element analysis (FEA) models of motors and generators to be created and solved in minutes. The two-dimensional (2D) version of the software has now been integrated with Cobham’s unique optimization tool which automatically finds the optimal solution within a design space – even for multiple or competing design objectives.
