Comparative Study of Hybrid Excited Axial Flux Switching Machine with Conventional and Phase Group Concentrated Coil Winding

This paper presents a comparison of hybrid excited axial flux switching machines (HEAFSM) with conventional winding and Phase Group Concentrated Coil (PGCC) winding. This study investigates the potential of increasing the output torque using Phase Group Concentrated Coil (PGCC) windings in a hybrid excited axial flux switching machine (HEAFSM). HEAFSM consists of ferrite magnets and field windings, allowing for adjustable excitation. To evaluate the effectiveness of the proposed machine, a comparative analysis between the conventional model and the PGCC windings model is performed using three-dimensional Finite Element Analysis (FEA). The FEA simulations provide valuable insights into the machine's performance, particularly in load torque capabilities. The analysis results indicate a significant increase in the average output torque of the HEAFSM with the inclusion of PGCC windings. Overall, this research highlights the potential benefits of incorporating PGCC windings in the design of axial flux switching machines. The findings suggest that the hybrid excited axial flux switching machine with PGCC windings can increase torque production and enhance the machine's overall performance.
