How to design an induction machine

The Induction Machine (IM) is the most widely used type of electrical machine. By some estimates it accounts for 90% of all small size motors (10 – 750W) and 60 -70% of medium size motors (0.75 – 375 kW). This is mainly due to their reliability, low cost and wide range of torque / speed [...] Posted in How to...,Induction Machines,Motors

Optimisation of Synchronous Reluctance Motors (SynchRels) using Opera

In the last few decades, the synchronous reluctance motor (SynchRel) has been relatively neglected in industrial, domestic and traction application because of the ascendency of permanent magnet (PM) and the ubiquitous induction (IM) motor. Recent vitality in rare earth PM prices and the unavoidable losses in IM’s have renewed interest in SynchRels – especially for [...] Posted in Motors,Synchronous Machines

NDT Device Design

Non-destructive testing or evaluation (NDT or NDE) is a process used in industry to evaluate properties of a material or a system without damaging it. Some of the uses of NDT are flaw detection and evaluation, leak detection, location determination, dimensional measurements, structure and Microstructure characterization, estimation of mechanical and physical properties, stress (strain) and [...] Posted in NDT Papers

MRI shielding webinar

In this webinar, we show the benefits Opera Optimizer offers when used in conjunction with magnetostatic analysis for MRI shielding applications. We also demonstrate the benefits of the new “thin plate” boundary condition, which increases efficiency without compromising accuracy, and how Opera provides the ability for shielded room designers to customize the Modeller and Post-processor [...] Posted in Magnets,MRI / NMR Magnets

EUGM 2017: Opera Update 2017

Presenter: Eddie Moor, Programme Manager, Cobham Technical Services Abstract: In this session the Opera Programme Manager will outline key updates in Opera. This will include an overview of recent and future developments as well as a sneak peek at some of the longer term projects for the Opera Roadmap, allowing users the opportunity to give [...] Posted in General

How to design a linear machine

In this blog I will take a look at the design of linear machines, where advanced material models are being used in order to investigate the effects of hysteresis on the machine characteristic. Linear machines are electrical motors or generators which transform mechanical energy into electrical energy and vice versa, through the use of linear [...] Posted in How to...,Linear Motion,Motors,Motors Papers

Electro-mechanical System Analysis using Opera and RomaxDesigner

Presenter: Dr. Melanie Michon, Romax Technology Abstract: The design of integrated electrified drivelines requires a holistic electro-mechanical approach. However, often electrical and mechanical components are designed separately, and problems don’t occur until the complete system is assembled and tested. In particular NVH problems are often caused by interactions between the electrical and the mechanical sub-systems [...] Posted in General,Motors,Motors Papers

How to simulate industrial designs for multi-physics applications

Opera is a suite of multi-physics analysis programs that includes electromagnetics, stress and thermal analysis. To highlight the main points that make it suitable for industrial designs: Opera includes an easy-to-use 3D Modeller, allowing models to be created or imported -in a wide variety of standard CAD formats; Scripting in the Modeller makes it a [...] Posted in Charged Particle Devices,CPD Papers,How to...,Induction Welding

Simulation of the H-injection system for the CERN Proton Synchrotron Booster in Opera-3d

Presenter: Jonathan Speed, CERN Abstract: The simulation of magnets for CERN particle accelerators is an essential part of the design process of new units, the analysis of the functionality of old ones, and even to guide the identification of magnet faults. One such application is the analysis of the future H- injection system for the [...] Posted in Accelerator Magnets,General
