In this Article dispersion characteristic of conventional optical waveguide with helical winding at core – cladding interface has been obtained. The model dispersion characteristics of optical waveguide with helical winding at core-cladding interface have been obtained for five different pitch angles. This paper includes dispersion characteristics of optical waveguide with helical winding, and ...

In this article, a circumscribing polygon integrated modular motor drive topology with shared cooling for the power converter and electrical machine is proposed benchmarked nonintegrated version. The applied on an axial flux permanent magnet synchronous machine. capable of mechanically mounting converter, sufficiently both machine, combining them into same housing. mechanical thermal design are...

Machine stator winding insulation degradation is one of the main results machine aging. It non-negligible once this process becomes asymmetric between phases. The traditional way to determine state health a partial discharge test. However, method requires system offline, which causes production loss and extra administrative burden. This paper presents an idea for better characterizing machine's...

Partial discharges (PD) are recognized as the main cause of the inner insulation deterioration process in power transformers. Therefore, the optimum inner insulation design is one of the challenges a transformer designer is faced with. Transformer strength, especially during transient conditions, is a criterion for transformer insulation designers. This challenge has made designers initiate and...
