ABSTRACT
Brushless DC (BLDC) motors have become a crucial component in modern industrial, automotive, and robotics applications due to their high efficiency, low maintenance, and precise control capabilities. This paper investigates various speed control techniques for BLDC motors, including Pulse Width Modulation (PWM), field-oriented control (FOC), and sensorless control methods. Comparative analysis of control strategies is performed using both simulation and experimental results. The study also explores torque-speed characteristics, dynamic response, and energy efficiency of BLDC motors under different control schemes. The findings demonstrate that optimized speed control not only improves system performance but also prolongs motor lifespan, making BLDC motors ideal for high-performance industrial and renewable energy applications.
KEYWORDS: Brushless DC motor, PWM, Field-oriented control, Sensorless control, Speed regulation, Torque control.
