Tóm tắt

This paper investigates how multiple flux barriers (FBs) affect the magnetic flux distribution and torque performance of Spoke-Type Interior Permanent Magnet Synchronous (SIPM) motors for electric vehicle (EV) applications. A 5-kW conventional SIPM motor serves as the baseline for comparison. The study first explores how multiple FBs influence the magnetic flux density, air-gap flux density, cogging torque, and inductance characteristics (Ld and Lq) under both no-load and load conditions. Applying a positive Id current lead to flux enhancement, increasing the effective PM flux density in the rotor. This results in higher torque output and reduces the risk of irreversible magnet demagnetization. Integrating multiple FBs into the rotor core yields significant performance improvements over a wide speed range. All findings are validated through finite-element method (FEM) simulations.
