Abstract:
Brushless Direct Current (BLDC) motors are universally used in industrial and domestic applications owing to their high efficiency, reliability, compact design, and low maintenance. Conventional Hall-sensor-based BLDC motors provide precise rotor position detection feedback and closed-loop regulation. These techniques commonly lead to problems such as the nonlinearity of motor properties, complexity, and higher system costs. Moreover, the non-appearance of mechanical commutators in BLDC motors requires innovative microelectronic control systems for commutation and drive regulation. This paper presents an effective method via Pulse Width Modulation (PWM) driven BLDC motor speed controller. The developed system uses an ESP32-WROOM microcontroller for wireless control and includes components such as an Infrared (IR) sensor, Electronic Speed Controller (ESC), and a 16X2 LCD display for better monitoring, control, and speed measurement. The proposed technique is anticipated to provide a cost-effective, flexible, and reliable solution for advanced motor control systems.
