Year: 2026
Type: conference-paper
Abstract: This paper investigates the impact of torque ripple on energy loss and efficiency in low-voltage brushless DC (BLDC) motors for two-wheel electric vehicle applications. A detailed electromagnetic analysis is conducted using the finite element method in ANSYS Maxwell under both no-load and load conditions at rotational speeds of 200 rpm, 520 rpm, and 550 rpm. Key performance indicators, including phase current characteristics, electromagnetic torque, torque ripple, loss, and overall efficiency, are evaluated and compared. The results indicate that torque ripple is significantly pronounced at low speed, leading to increased current distortion and higher energy losses. In contrast, more stable operation with improved efficiency is observed in the medium-speed range. The findings provide valuable insights for improving the energy performance and operational stability of low-voltage BLDC motors in two-wheel electric vehicle applications.
