N2 - Challenges such as the demagnetization of permanent magnets (PMs) due to high temperatures in high-speed applications, alongside the potential advantages of soft magnetic materials, offer new opportunities for improving electrical machines from a materials perspective. In this paper, the utilization of semi-hard (SH) magnetic material in the rotor of the switched reluctance motor (SRM) leads to a novel topology designed for 24,000 rpm. The topology is designed to reduce the stator core losses while maximizing both average and peak torques at high-speeds, aiming for high efficiency. An overview of the SRM's design, including the core loss model is presented. The Jiles-Atherton (JA) method is chosen for dynamic calculations. Electromagnetic characteristics of the studied motor is obtained by the finite element method (FEM). The contributions of hysteresis and reluctance torques in the novel SRM are identified to validate the effectiveness of the proposed strategy.
