Abstract
The performances of a novel flux reversal claw pole machine (FRCPM) using soft magnetic composite (SMC) cores is analyzed in detail. The developed FRCPM uses both a flux reversal permanent magnet machine (FRPMM) and claw pole machine (CPM). In this paper, the main dimensions are optimized to ensure that the FRCPM can achieve maximum torque. In addition, the rotor skewing technology applied in the paper leads to a reduction in cogging torque and torque ripple of the machine. The main electromagnetic parameters and performance are obtained using the 3D finite element method.
Highlights
As a special kind of permanent magnet machine, flux reversal permanent magnet machines (FRPMM) have a particular topology: the permanent magnets (PM) and windings are both located on the stator side of the machine, while the rotor side only has an iron core [1,2,3,4]

Summary
As a special kind of permanent magnet machine, flux reversal permanent magnet machines (FRPMM) have a particular topology: the permanent magnets (PM) and windings are both located on the stator side of the machine, while the rotor side only has an iron core [1,2,3,4] Such structure displays some advantages, such as high torque, high fault tolerance, and mechanical robustness. This paper will focus on the optimization of a new flux reversal claw pole machine (FRCPM) with SMC cores to weaken its cogging torque and torque ripple. Thethe main parameters andand performance areare obtained. 1b shows the main dimenvery robust andand satisfies thethe high-speed requirements.
