Analytical Iron Loss Evaluation in the Stator Yoke of Slotless Surface-Mounted PM Machines
Leandro, Matteo; Elloumi, Nada; Tessarolo, Alberto; Nøland, Jonas Kristiansen (Peer reviewed; Journal article, 2022)One of the attractive benefits of slotless machines is low losses at high speeds, which could be emphasized by a careful stator core loss assessment, potentially available already at the pre-design stage. Unfortunately, ... -
Analytical PM Eddy Currents Loss Evaluations in Inverter-Fed Slotless Machines Induced by SVM Control Using Polar Coordinates Formulations
Leandro, Matteo; Nøland, Jonas Kristiansen (Peer reviewed; Journal article, 2023)Space vector modulation (SVM) is a widespread method for controlling PM machines. However, the switching harmonics contribute to eddy current losses in the magnet region. In the analytical modeling of slotless PM machines, ... -
