The design and analysis of a Brushless DC (BLDC) motor system driven by renewable energy sources, including solar photovoltaic (PV) and battery storage, are presented in this paper. A voltage source inverter (VSI) is used by the system to effectively drive the BLDC motor. BLDC motors are energy efficient and are a better option for agricultural motor drive applications due to their optimized efficiency and speed modulation capabilities. The efficiency of the solar PV source employed, has been improved through effective incorporation of metaheuristic maximum power tracking technique, ensuring the operation of the solar PV panel at the peak power point in dynamic environments. The implementation of tracking the maximum operating point of power has been done based on Whale Optimisation algorithm, which continuously monitors and adjusts the solar panels operating point to maximize energy output. An interleaved boost converter has been employed to regulate the PV output and feeding the battery. The combined battery-solar PV is efficaciously integrated with the VSI to provide a stable power supply to the BLDC motor with electronic commutation. The regenerative braking operation of the motor has been simulated and results analyzed. Also the comparison of the boost converter and interleaved boost converter has been substantiated.
