Abstract

This paper analyzes the performance of a brushless direct current (BLDC) motor for agro electric vehicle (agro-EV) applications. Agro-EV technology is being developed in response to increasing environmental pollution. Various types of electric motors are in agro-EV, one of which is the BLDC. With its good capabilities, it has been chosen for further exploration in this research. On the other hand, some issues limit the usage of the conventional BLDC motor in heavy applications, such as low torque performance caused by weak magnetic energy. Therefore, this research aims to analyze the effect of magnetic energy based on slot-pole combinations to evaluate the BLDC motor's performance. Three BLDC models with different slot-pole numbers are designed and simulated using a fixed structure size, permanent magnet volume, and magnetomotive force (MMF). Finite element method (FEM) software known as Altair Flux 2D is used to compute the cogging torque, back-electromotive force (BEMF), magnetic flux density, and the torque produced. As a result, an 18/20 slot-pole was chosen for its high torque (105 Nm) and BEMF (35.9 V). In conclusion, this research simulation presents guidelines and an overview regarding the effect of slot-pole numbers on the performance of the BLDC motor for agro-EV applications.
