Unbalanced Torque Signal Generation for Kinetic Energy Harvesters

L. Kurmann [1],
[1] University of Freiburg, IMTEK, Freiburg, Germany

The problem of an unbalanced mechanical torque signal generation using nonpolar repulsion techniques is studied. To achieve such an unbalanced torque, several stator and rotor geometries, consisting of nonlinear permanent magnet spring batteries are investigated. It can be shown that an ... En savoir plus

Seat Motor Design Optimization

S. Qi [1], H. Cheng [1], L. Yang [1]
[1] Dare Auto, Inc., Plymouth, MI, USA

In this work, the production intent design of a motor with controller inside a car seat for head restraint function is analyzed and optimized using the COMSOL Multiphysics® software and the Application Builder. Parameter based multiscale FEA models were developed by using external CAD ... En savoir plus

Finite Element Modeling of a Microwave Cavity under Resonant Conditions

T. W. Krause [1], F. Liu [1], S. Gauvin [2],
[1] Department of Physics and Space Science, Royal Military College, Kingston, ON, Canada
[2] Department of Physics, Engineering Physics and Astronomy, Queens University, Kingston, ON, Canada

A tapered cylindrical microwave resonant cavity, a frustum, also commonly known as an EM Drive, has been reported to produce thrust by the generation of EM radiation within a resonant cavity without using any propellants. In order to determine how a sealed microwave cavity can produce ... En savoir plus

Analyzing Electromagnetic Modes of Integrated Busbars Implemented as Printed Circuit Boards (PCB)

A. Pokryvailo [1],
[1] Spellman High Voltage Electronics Corp., Hauppauge, NY, USA

This report addresses design of a PCB intended for use as a busbar integrated with multiple DC-link (rail) capacitors in a high power inverter. The geometry and current ratings are typical of a 50 kW unit operating at 60kHz in an intermittent mode. First, circuit aspects are analyzed. ... En savoir plus

Modeling of Electro-Thermal Microbolometer for Thermal Imaging

A. Nowicki [1], A. Bennecer [1],
[1] Mechanical Engineering, University of Northampton & Gdańsk University of Technology, Gdańsk, Poland
[2] Engineering, University of Northampton, Northampton, United Kingdom

A Microbolometer is a specific type of uncooled infrared radiation detector used in thermal cameras, which converts the incoming energy into a proportionate electrical signal, which is then amplified, processed and displayed, typically on the thermal camera’s LCD viewer. The main ... En savoir plus

[1] JPM Silicon GmbH / Technical University of Braunschweig, Braunschweig, Germany

As a high-tech silicon producer, it is our goal to provide efficient and sustainable production technologies. This requires to constantly upgrade our production concept. Thus, material and design innovations are an inevitable part of our everyday work, which leads our microwave ... En savoir plus

Multiphysical Simulation of an Induction Sealing Process for Cups with Laminated Aluminum Foil

C. Hollenbeck [1], Z. Jildeh [1], P. Kirchner [1], T. Rydlewski [1],
[1] Imagine Engineering GmbH, Bergheim, Germany

The filling process of thermoformed cups with food like yogurt is followed by placing a laminated aluminum foil for hermetic sealing on top of the cup. By today’s standards the sealing of the thermoformed aluminum foil with the cup is primarily realized by contact heat with a hot stamp. ... En savoir plus

Design and Optimization of Power Cable Accessories Using COMSOL Multiphysics®

A. Lewarkar [1], D. Bergsma [1], S. Madhar [2],
[1] E&D Department, Lovink Enertech B.V., Terborg, Netherlands
[2] Electrical Engineering Department, Delft University of Technology, Delft, Netherlands

Power cable manufacturing is limited by the maximum length of cable that can be produced and stored on cable drums. This creates a need or rather an opportunity for a cable accessory, namely 'Cable Joints'. Joints are an impeccable component in the power cable network that necessitate ... En savoir plus

Simulation and Visualisation of Shielding Gas Flows During Wire-Arc Additive Manufacture

I. Bitharas [1], A. Moore [1],
[1] Heriot-Watt Univerisity, Edinburgh, UK

One of the challenges associated with the wire-arc additive manufacture (WAAM) of metals is to provide adequate inert gas shielding, not only for the molten pool, but also for the long reactive metal surface that follows it. For Ti-6Al-4V, it has been shown that increased levels of ... En savoir plus

Finite Element Method based Investigation of IPMSM Losses

M. Schmidtner [1], C. Markgraf [1], A. Frey [1],
[1] University of Applied Sciences, Augsburg, Bavaria, Germany

INTRODUCTION: This paper investigates the design of IPMSM as drive motor for an electric race car in the competition called Formula Student. A key parameter for electrical motor is the power density which is very important for the performance of such race vehicles [1] to keep the overall ... En savoir plus
