[3]Institute of Materials Sciences, University of Connecticut, Storrs, CT, USA

3D finite element analysis model has been constructed for testing the directional dependence in a novel form of nanowire array gas flow sensor. Single nanowire (p-type single crystal Silicon) model is developed using fluid structure interaction and piezoresistivity components in the MEMS ... En savoir plus

3D Modeling and Analysis of a Mock-up Ironless Stator Design for Electrical Machines

T. Aravindakshan¹, Dr. P. Masson²
¹Florida Institute of Technology, Melbourne, FL, USA
²AML Superconductivity and Magnetics, Melbourne, FL, USA

With the evolving trend of electrification in transportation, electric machines with higher power density and higher efficiency are demanded which results in the thermal limit of the stator winding becoming more of a key constraint. The achievable current density in stator windings is ... En savoir plus
