چکیده
Radial flux brushless DC motors with surface-mounted permanent magnets offer several advantages, but they are also characterized by a significant drawback: high cogging torque. Mitigating cogging torque is a critical challenge in the design of brushless direct current motors, particularly in applications such as electric vehicles. This article presents three approaches to reduce cogging torque in radial flux permanent magnet brushless motors: teeth edge inset width variation, magnet tip depth variation, and a hybrid approach combining both techniques. The teeth edge inset width variation method involves reducing the inset width of the stator teeth, while the magnet tip depth variation approach addresses the depth of the magnet's edge inset on the rotor core surface. The hybrid approach integrates changes to both the stator teeth and rotor magnet poles. Additionally, the study investigates how these approaches affect the average torque and flux density distribution. Finite element analysis was conducted to simulate and analyze a 1000 W, 510 rpm radial flux brushless DC motor. The results show that the proposed methods effectively reduce cogging torque, demonstrating their potential to enhance the performance of these motors in practical applications.
