Abstract – The design process of a double-sided slotted TORUS axial-flux permanent-magnet (AFPM) motor suitable for direct drive of electric vehicle (EV) is presented. It used sizing equation and Finite Element Analysis (FEA). AFPM motor is a high-torque-density motor easily mounted compactly onto a vehicle wheel, fitting the wheel rim perfectly.
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.
Les concepteurs des machines électriques tournantes d’aujourd’hui sont l’objet de pressions pour offrir des moteurs plus efficaces, robustes et innovants et dans des délais toujours plus courts. Au cours de ce webinaire Cobham Technical Services – Vector Fields Software montrera comment la Suite Opera peut être mise à profit pour apporter l’exactitude de l’analyse par éléments finis (FEA) avec la facilité d’utilisation des logiciels de conception analytique.
Opera is a general-purpose finite element software suite for the design and optimization of electromagnetic devices in two or three space dimensions. The software has been in continuous development since 1984, and its accuracy and capabilities for multiphysics analysis has made it a firm favourite in both scientific and industrial communities. The ability to couple electromagnetic analysis to built-in thermal and stress solutions, along with drive circuits, mechanical drives and system representations allows in-depth analysis. Remove assumptions and bottlenecks from your design process and deliver right-first-time products.
Today’s designers of rotating electrical machines are being pressured to deliver more efficient, robust and innovative motors and generators in ever-shortening timescales. In this webinar Cobham Technical Services – Vector Fields Software will show how the Opera Suite can be used to deliver the accuracy of Finite Element Analysis (FEA) with the ease-of-use of analytical design packages.
* ability to run 1000s of optimisation searches helps Siemens make breakthroughs such as permanent magnet generators.
Cobham Technical Services has been awarded a contract for its powerful Opera electromagnetic design tool by Siemens Wind Power, a leading supplier of wind turbines for onshore, offshore and coastal sites.
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.
Abstract — This paper presents the optimal design and development of an axial flux motor for blood pump application. With the design objective of maximizing the motor efficiency and torque, different topologies of AFPM machine has been examined.
Abstract – This thesis consists of two parts, the first dealing with the design of iron-powder synchronous machines, and the second with the analysis and prediction of the acoustic noise in electrical machines.
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 and predicting performance changes due to hysteresis effects in the specialty electrical steels that are increasingly being used to enhance machine efficiency.
