Abstract
Electric vehicle (EV) technology depends on efficient motor systems to optimize performance, reliability, and sustainability. Among the various motor types, Brushless DC (BLDC) motors have become a primary choice due to their high efficiency, durability, and minimal maintenance needs. Recent advancements in BLDC motor technology have focused on improving design, control strategies, and fault tolerance to meet the growing demands of EV applications. Studies have shown that the use of six-phase BLDC motors can enhance power output and reduce vibration at high torque loads, which is critical for smooth operation under diverse driving conditions . Moreover, advanced control techniques, such as closed-loop speed control and field-oriented control, have been integrated to optimize motor efficiency and responsiveness, contributing to better energy management and smoother vehicle operation. In addition, hybrid energy systems combined with BLDC motor drives are being explored to extend the range and performance of electric vehicles by efficiently managing energy from multiple sources. The development of fault-tolerant systems is also crucial, allowing BLDC motors to maintain operational stability in case of component failures, thus increasing the overall reliability of EVs. This paper reviews the latest advancements in BLDC motor design and control, underscoring their role in enhancing the performance and reliability of electric vehicles
