FEM-based Analysis of a Hybrid Synchronous Generator with Skewed Stator Slots
The paper presents a simulation study of a hybrid synchronous generator (dual excitation system - permanent magnets and electromagnets) with skewed stator slots. The main goal is to establish if the skewing of the slots brings a significant improvement of the air-gap flux density and of the induced stator voltage. The skewness angle is the parameter in discussion. The study is based on finite element method analysis. Due to the particular geometry of the stator slots, a multilayer approach is employed
