An Analytical Model for Detailed Transient Fault Analysis of Doubly-Fed Induction Machines
Maurer, Frederic; Nøland, Jonas Kristiansen (Chapter, 2020)This paper presents an exact analytical solution to the two-phase and three-phase short-circuit events of the doubly-fed induction machine (DFIM). The contribution is intended to strengthen the predictability of DFIMs under ... -
Generalized and Reduced Analytical Formulation for Ultra-Fast 3-D Field and Vector Potential Calculation from Arch-Shaped Axially Magnetized Bodies in Electrical Machines
Maurer, Frederic; Kawkabani, Basile; Nøland, Jonas Kristiansen (Peer reviewed; Journal article, 2020)Arch-shaped axially magnetized bodies tend to appear frequently in electrical machine analysis such as in overhang parts of classical radial-flux machines as well as in main parts of axial-flux machines. The calculation ... -
Rapid 3-D Magnetic Integral Field Computation of Current-Carrying Finite Arc Segments with Rectangular Cross-Section
Maurer, Frederic; Kawkabani, Basile; Nøland, Jonas Kristiansen (Journal article; Peer reviewed, 2020)The computation of three-dimensional (3-D) magnetic fields is a demanding task in the analysis of electrical machines and other electromagnetic devices. In this context, integral field calculation provides a smooth solution, ... -
A Rectangular End-Winding Model for Enhanced Circulating Current Prediction in AC Machines
Maurer, Frederic; Nøland, Jonas Kristiansen (Peer reviewed; Journal article, 2020)The end-winding region is usually overlooked in the roebel design of large AC machines. However, saturated stator slots cause overhang parts to impact the circulating currents significantly. In fact, a precise knowledge ...
