Abstract

lowering dependency on non-renewable energy sources and encouraging a more environmentally In this research, a multilayer inverter powered by an Arduino Uno microcontroller is used to build and implement an improved speed control system for Permanent Magnet Synchronous Motors (PMSM). Because of their great efficiency, portability, and dependability, PMSMs are being utilized more and more in vital applications including electric cars, renewable energy systems, and industrial automation. It is still difficult to provide accurate and energy-efficient speed control under different load circumstances. By integrating a multilayer inverter, which drastically lowers harmonic distortion, eliminates torque ripple, and enhances overall motor performance, this project overcomes these difficulties. The core controller is an Arduino Uno microcontroller that has been configured to interpret real-time output from a Rotational Position Sensor (RPS). Closed-loop control for accurate motor speed changes is made possible by this feedback. An SMPS powers the system, highlighting its low power usage and operational effectiveness. Furthermore, the solution makes use of sophisticated Pulse Width Modulation (PWM) methods, which allow for more precise control over the motor drive and inverter. The project demonstrates the benefits of a modular design, where scalability and cost-effective prototyping are made possible by the use of easily accessible components like the Arduino Uno. In addition to enhancing power quality, the multilayer inverter construction guarantees compatibility with a broad variety of operating frequencies and load situations. Applications for this technology include electric propulsion systems, precise manufacturing facilities, and renewable energy installations such as wind and solar power generating. The system's capacity to produce improved stability, less electromagnetic interference, and smooth motor performance is confirmed by the testing findings. By integrating cutting-edge hardware and software techniques to push the limits of motor control technology, this study represents a step toward developing sustainable and flexible motor control solutions for contemporary engineering difficulties.
