Introduction to ME2D – Induction Machine Finite Element Model Construction & Analysis


Introductory video showing the use of the two dimensional machines environment (ME2D) with Opera-2d in building, simulating and post-processing a parametric model of an induction machine. The environments provide ready-made generic designs, together with application-specific data entry and advanced optimization techniques, all expressed in the language of the application. The environments provide a strategic framework […]


Innovative electromagnetic design tool for motors and generators is extended with new ready-to-use models and hysteresis solver


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 […]


New modelling tool simplifies development of next-generation automotive power steering


A new magnetic hysteresis solver for electric motor and electromagnetic design has been released by Vector Fields, a business unit of Cobham plc. The tool’s ability to accurately characterise hysteresis effects provides a powerful means to optimise the performance and fidelity of new-generation electrically-assisted automotive power steering systems, and other high-performance actuators.


Electromagnetic simulation advance helps electrical machinery designers to achieve ultimate efficiency


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 […]


Optimizing a Quadrupole Magnet


In this example the Optimizer is used with Opera-3d to optimize the performance of a quadrupole magnet used in charged particle beam lines. Auto-optimisation tools are not new, but they usually require manual intervention if a globally-optimal solution is to be found. And simulation times often make such a process impractical. A new tool – […]


Electromagnetic Simulator Cuts Time to Market for Pioneering Magnetic Drive Technologies


Advanced modelling capabilities in the Opera electromagnetic simulator are helping Magnomatics to bring ground-breaking magnetic power transmission innovations to market. A recent spin-out from the University of Sheffield, Magnomatics is currently working with numerous organisations on magnetic gearing and power transmission applications. Among the advantages of its magnetic linkage technology are long maintenance-free lifecycles, very […]


Electromagnetic modeling package speeds design of active electron optic X-ray tubes for Philips Medical Systems


The three-dimensional version of Vector Fields’ specialized electromagnetic modeling algorithm for charged particle beams is playing a key role in the development cycle of Philips Medical Systems’ first commercial X-ray imaging systems with ‘active optics’. Active beam technology supports dynamic focusing and positioning of the electron beam during investigation procedures, greatly improving the resolution and […]
