In recent years, electric vehicles (EVs) have attracted a lot of attention and are rapidly growing trends today due to their ability to compete with and overtake fossil fuel-powered vehicles among all electrified transportation tools. The primary focus of EV evolution is on improving driving range and optimizing energy consumption, both of which are essential demands achieved through improved and developing motor performance. The brushless direct current (BLDC) motor is one of the most superior choices for dynamic applications in EVs, providing the highest power density and capability of any motor. BLDCs are gaining popularity in EVs not only for their high performance in speed and position controls but also for meeting the requirements of smooth torque maintenance with torque ripple mitigation. This paper provides an overview of various advanced control strategies, such as field-oriented control (FOC), direct torque control (DTC), intelligent control (IC), controlling input voltage (CIV), current shaping techniques (CST), model predictive control (MPC), and sliding mode control (SMC). These strategies are used to regulate the torque ripples produced in BLDC motors, aiming to achieve energy-efficient EV performance for various applications. Additionally, it describes a cloud-based control system coupled with electric motor drives to address challenges in predicting current vehicle conditions for improved power distribution between the motor and battery systems. Furthermore, recent concerns and difficulties in advancing torque ripple mitigation control strategies are highlighted, with comparisons and discussions for future EV research. Finally, an evaluative study on BLDC motor drive in EVs with different control strategies reveals its significance and potential outcomes.

“…The parameters that influence the flux connection, stator groove flux density, and flux pulsating elimination include the total number of coils, thickness of the slot crossing, the dimension of the stator core, which are the size of the stator groove [5]. The stator grooves have a significant impact on various aspects of thermal energy preservation, such as stator leaking reaction, electromagnetic flux connection, and extra energy loss [6]. The development of a high-speed spindle drive can be achieved by employing several techniques such as expert stationary spindle architecture [7], the Taguchi approach, and finite element method (FEM) as well as response surface methodology (RSM) and FEM [8].…”

A novel approach was devised to optimize the stator slot semi-closed type in order improve the magnetic flux connection and minimize iron leakage in high-speed spindle drives. The concept was executed through a combination of response surface approach including the technique of finite element analysis. The primary objective of this investigation would be to provide an engineering approach which improves the functionality of stator criteria, including the stator slot geometry, coil turn per slot, and wire size. The purpose is to achieve higher flux connection and minimize iron leakage. This study presents an enhanced analytical approach that incorporates the analysis of stator flux connection, finite element calculation of flux connection, and iron leakage analysis of stator variables. The results are analyzed through the utilization of finite element computation, and their accuracy is verified through experimental measurements. The findings suggest the ideal design yields increased magnetic flux connection and reduced iron leakage in comparison to the industrial layout. The precision provided by the suggested model is confirmed through the comparison of the simulation and experimental information. In general, the percentage of errors is estimated to be around 7%.

“…The surface mount magnet configuration is the most common for permanent magnet motors, with a magnet located on the outer surface of the rotor core. However, this design is vulnerable to high centrifugal force, which might lead to catastrophic failure [7]- [9]. An interior magnet rotor is a feasible alternative that should be researched further to resolve this [10], [11].…”

<span lang="EN-US">The permanent magnet of brushless DC (BLDC) motor is ideally suited for high-speed application due to its superior performance and efficient as compared to other types of electrical motors. However, to operate in high-speed operation, the rotors that hold the magnet must be able to withstand high centrifugal force. Due to that, the main objective of this project is to design and develop the suitable rotor for high-speed BLDC motor through the finite element method (FEM) Ansys Maxwell modeling software. In addition, this project is also carried out to determine the ability of the modeled software to reach the high-speed performances in terms of cogging torque and induce voltage. In this project, the selected BLDC motor was fabricated and measured experimentally. The result showed that the designed rotor can achieve speed of almost 14,500 rpm.</span>
