Abstract

Background

In response to the need for improved performance in electric machines, this paper introduces and evaluates a novel hybrid excitation partitioned stator flux-switching (HEPSFS) machine. This design optimizes output torque while considering power density, torque density, and overall efficiency.

Objective

The primary objective is to enhance electromagnetic torque production by minimizing flux leakage to the inner-stator core by creating an auxiliary air-gap in the inner-stator tooth. Additionally, a partitioned stator design is adopted to accommodate armature and field windings without space conflicts, allowing for increased windings and permanent magnets (PMs) to maximize torque density and flux regulation capability.

Methods

A comparative analysis is performed with a conventional HEPSFS (CHEPSFS) machine to evaluate the proposed design. Both machines share the same design dimensions and winding configuration to ensure a fair assessment. Finite Element Method (FEM) simulations using ANSYS Maxwell software are conducted to validate the results.

Results

The analysis reveals that the proposed HEPSFS (PHEPSFS) machine outperforms the conventional counterpart. It exhibits higher torque output, torque density, power density, and efficiency while minimizing torque ripple. Moreover, at a current angle of 0 degrees, the PHEPSFS machine shows substantial percentage improvements compared to the CHEPSFS machine: a 285% increase in torque output, a 281.39% rise in power density, a 283.82% enhancement in torque density, and a 9.14% boost in efficiency. Furthermore, the PHEPSFS machine design reduces torque ripple by an impressive 59.63% compared to the CHEPSFS machine design.

Conclusion

The study concludes that the PHEPSFS design effectively optimizes torque performance, making it a promising advancement in HEPSFS machines.
