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

Posted on September 18, 2012 by admin

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

Posted on June 14, 2012 by admin

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.

Innovative electromagnetic design tool provides short route to motor perfection

Posted on February 1, 2012 by admin

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.

Genetic algorithm and finite element analysis for optimum design of slotted torus axial-flux permanent-magnet brushless DC motor

Posted on August 11, 2011 by admin

Abstract – This paper presents an inside-out axial-flux permanent-magnet brushless DC motor optimized by Finite Element Analysis (FEA) and Genetic Algorithm (GA) that uses sizing equation. The double-sided slotted-stator designed TORUS motor has sinusoidal back EMF waveform and maximum power density. The GA obtained the dimensions that gave the motor its highest power density. Field analysis of the dimensions was then put through FEA, to obtain and re-optimize the motor’s characteristics.
