One of the most viable options presented for eliminating environmental concerns while keeping energy efficiency in the field of mobility and transportation, is electrical vehicles (EV). The overall performance of the electrical vehicles can be determined by their electric motors. The utilization of the permanent magnet brushless direct current (PMBLDC) motors as an applicable selection for the electrification of the vehicles. In this research, a deep examination and performance evaluation of the use of PMBLDC motors in electric vehicles, in precise a comparison of a simplified and complex models of a three-phase, 4-pole Y-connected PMBLDC motor was performed. Performance evaluation and enhancement and assessment of behavior under ambient temperatures and various controlling algorithms, was done by creating the models using MATLAB/Simulink environment. The research resulted in optimizing the overall performance of the motor as well as the full electric powertrain.
