Radial Force Analysis and Optimization of Interior Permanent Magnet Traction Motor for Reduction of Electromagnetic Vibration
TL;DR: In this article , the radial force harmonics were analyzed and effectively reduced by rotor notching and asymmetric stator slotting techniques, and the results showed 97.0% and 54.7% amplitude reduction on 48th temporal harmonic of total radial force for open-circuit and on-load operation.
Proceedings ArticleDOI
Proposed methodology to combine design concept and manufacturing process selection for distributed wound stator cores
TL;DR: In this paper, the authors quantitatively assess conventional and novel stator core design features and the available manufacturing technologies, and propose a method of motor component design and process selection which enables multiple novel component design features to be effectively combined and assessed for their manufacturability and their electromagnetic performance.
