Investigation into the impact of geometric parameters on cogging torque and efficiency in brushless DC motors has highlighted significant considerations for motor design. Cogging torque, a crucial factor in the performance of brushless DC motors, arises from the interaction between the permanent magnets and the slots of the stator, leading to variations in angular speed and torque ripple. By analyzing different geometric parameters, researchers aim to optimize motor design to reduce cogging torque, thereby enhancing efficiency and performance. This study outlines methodologies for evaluating these parameters, providing insights that can inform the development of advanced motor technologies with improved efficiency and reduced noise, contributing positively to the overall reliability and functionality of brushless DC motors in various applications.
