Use of FEM in the Design of an HTS Insert Coil for a High Field NMR Magnet

E. Bosque[1]
[1]Applied Superconductivity Center, National High Magnetic Field Laboratory, Tallahassee, FL, USA

High temperature superconductors (HTS) allow larger current densities through coil wound electromagnets, which produce higher magnetic fields. A high field HTS insert demonstration magnet is being built with high field homogeneity (~1 ppm) for application in nuclear magnetic resonance ... Read More

Prediction of Transformer Core Noise

R. Haettel[1], A. Daneryd[1], M. Kavasoglu[1], C. Ploetner[2]
[1]ABB Corporate Research, Västerås, Sweden
[2]ABB Transformers, Varennes, QC, Canada

Today, low noise is a mandatory feature for power transformers to comply with customer specifications and environmental regulations. Therefore, it is crucial to develop sound prediction tools with sufficient accuracy to avoid overkill margins in design and costly modifications after ... Read More

Prediction of Noise Generated by Electromagnetic Forces in Induction Motors

M. K. Nguyen[1], R. Haettel[2], A. Daneryd[2]
[1]KTH, Stockholm, Sweden
[2]ABB Corporate Research,Västerås, Sweden

Induction motors, as any other industrial products, have to comply with various requirements on noise levels. Therefore, it is essential to use an appropriate prediction tool to verify and optimize the design of an induction motor with respect to the acoustic performances. The paper ... Read More
