One of the cornerstones of developing energy-efficient policies in the field of electric mobility is the arrival of brushless direct current (BLDC) motors. In this paper, a detailed discussion of the BLDC motor systems is presented, including the design, modelling, and control strategies to ensure more efficient use of the motor system to achieve greater energy efficiency in car motors. The paper talks about the principles of the work of the BLDC motors as well as the use of position sensors, electronic commutation, and the dynamics of the inverter. The mathematical model of BLDC motors is described in detail, with the focus being placed on the reduction of the highly complicated 3-phase systems to simpler d-q reference frames to simplify the analysis. A range of control methods, including proportional-integral-derivative (PID) controllers, is also examined in the research, and the importance of their role in obtaining accurate control of speed and torque is mentioned. Introduction of power electronics, such as inverters and pulse-width modulation (PWM) methods, is also dealt with to enhance the efficient functioning of a motor. Moreover, the paper discusses closed-loop control systems that stabilise and operate under a diverse environment, and this is fundamental to the application of electric vehicles. Transient analysis and dynamic response of the BLDC motors are given special attention so as to optimise the use of energy. The work will be used as a reference guiding researchers and engineers who want to develop the current technology of the BLDC motors to achieve sustainable electric mobility systems.
