Simulation and Performance Analysis of an Electric Racing Car Powertrain: BLDC Motor Control

Abstract

Electric racing cars require high-performance powertrain systems to achieve efficient energy utilization and optimal driving dynamics. This research presents a simulation-based analysis of an electric racing car powertrain, focusing on a critical subsystem: BLDC motor operation. A MATLAB/Simulink model of a three-phase BLDC motor is developed, incorporating a PI-based control mechanism to drive the motor at a specified speed. The simulation evaluates key parameters such as motor current, power consumption, and torque characteristics. Unlike previous studies that examine motor control and energy storage separately, this work integrates both components in a unified simulation framework, offering a comprehensive view of the powertrain operation. The results demonstrate that the BLDC motor successfully runs at the desired speed. This study provides insights into the operation of BLDC motors for energy delivery systems in high-performance EVs, making it valuable for the development and optimization of next- generation electric racing cars.
