This paper conducts a comparative study upon the performance of an electrical machine fitted with alternative winding conductor materials. The study focusses on an existing interior-mount PM machine (IPM), which is wound with copper (Cm) conductors in a single-layer “modular” topology. An analysis exercise is performed to investigate the impact of using alternative conductor materials, such as Aluminium...
We calculated the refractive index from Sparameter data for corrosion samples tested in waveguide from 12.4 GHz to 110 GHz. This approach minimizes the modal noise often seen in derived permittivity and permeability for low-loss samples in this range. Also, any resonance absorption due to atomic structure is made clearly discernible. We are interested in observing spectral signatures with network...
