Web Server Based Soft Starter for DC Shunt Motor

Automation has become a significant topic in the 21st century, thanks to the advancements in robotics, artificial intelligence, and machine learning. It offers the potential to reduce human effort and time, resulting in improved productivity and efficiency. In this paper, we present an innovative idea for creating a web server-based speed control system for DC shunt motors using the ESP32 microcontroller. The system enables users to regulate the speed of a DC shunt motor from any location. in the world using a web browser or a mobile app. By integrating a web server with an ESP32 microcontroller, the system provides a flexible and versatile solution for industrial automation, home automation, and DIY projects. To use the ESP32 to develop web server-based speed control of a DC shunt motor, a web page will be created and hosted on the microcontroller. Users will be able to create a changeable duty cycle pulse-width modulation signal for the DC motor using an HTML slider on the website. The SEMIKRON kit module will be used to interface with the motor and convert the PWM signal to a variable voltage that controls the motor speed. This setup provides an intuitive and user-friendly interface for remotely controlling the motor speed. The duty cycle value is set by adjusting the slider. The PWM signal produced by the ESP32 will be set based on the position of this slider. In essence, this variable duty cycle PWM will regulate the DC motor's speed. The webpage in the mobile or laptop and the Esp32 controller should be connected in the same Wi-Fi. Within the Wi-Fi range the motor speed was controlled. This method of web server-based speed control offers several advantages over traditional methods. It reduces the complexity of the system by eliminating the need for extensive wiring and hardware. The use of the ESP32 microcontroller and SEMIKRON kit module provides a portable and scalable solution that can be easily adapted to various industrial automation systems. The system also offers greater flexibility for remote operation and control. Operators can connect wireless network and use HTML slider on the web page to the DC shunt motor's speed should be adjusted and observed. This provides a simple and intuitive interface for controlling industrial motors, saving time and reducing human effort.
