This study proposes a Switched Reluctance Motor (SRM) for high-speed cone crusher applications, utilizing a combined Discrete Element Method (DEM), Finite Element Method (FEM), and Response Surface Methodology (RSM) approach for design optimization. DEM simulations on a cone crusher model show increased speed enhances throughput and power consumption. Larger feed sizes perform well at low speeds, while smaller sizes benefit from high speeds. Based on these findings, an SRM with suitable power and speed ratings was designed using FEM. Geometrical optimization via RSM focused on minimizing torque ripple, maximizing average torque, and efficiency, resulting in a torque ripple reduction from 80% to 45% and efficiency improvement from 86% to 89%, with average torque near the rated 7 Nm. A prototype SRM was fabricated and experimentally validated. This study demonstrates the effectiveness of the DEM-FEM approach in accurately determining motor requirements for specific applications. |
