Abstract

Issues related tohouseholdor small-scale industrial waterpump systemsoften involve energy efficiency andthe reliability of motor control. One effective solution is the implementation of a Brushless AC (BLAC) motor, which offers advantages such as high efficiency, high torque, and precise speed control. This study aims to design and implement a speed control device for a single-phase BLAC motor applied to a waterpumpsystem. The speedcontrol systemisbased on Pulse Width Modulation (PWM) signals, utilizing key components such as a microcontroller, motor driver, speed sensor, and a TRIAC as the main actuator.The research methodology includes circuit design, simulation using Proteus software, and direct performance testing. The test results show that the system can smoothly regulate the speed of the BLAC motor and respond effectively to load variations.The success of this design is expected to provide an applicable solution for BLAC motor-based water pump systems, offering more flexible and energy-efficient speed control.
