Intelligent Power Controller for BLDC Motor

Abstract

Now-a-days BLDC motors are used in many applications including electric vehicles. The battery-operated vehicles are gaining popularity as people become increasingly aware of the adverse effects of fossil fuel-powered vehicles on the environment. These battery- operated vehicles are equipped with the Brushless direct current (BLDC) motor due to its high efficiency. Many researchers carried out researches to regulate the operations of BLDC motors. In this research the control of BLDC motor is analyzed. While taking into account reliability and durability, the BLDC motor fails to provide an increased fault tolerance, with decreased electromagnetic interference, acoustic noise, flux ripples, and torque ripple. Torque ripple in a BLDC motor’s is mainly caused due to the variation in the interactions across the stator and rotor as well the electromagnetic fields. So, the research has come up with the solution to the torque ripple using the controllers. By using intelligent power controllers, the output performance can be improved with good power quality and efficiency.
