Design and Fabrication of an Inductive Motor with Spike Suppression Mechanism for Power-On Stability

This study focused on the design and development of an inductive motor equipped with a spike suppression mechanism to address the challenges of power surges during startup, enhance energy efficiency, and improve operational reliability. Inductive motors, widely used in industrial and residential applications, often face issues with electrical spikes that compromise their efficiency and lifespan. The developed motor controller system integrates an inverter circuit and spike suppression mechanism, resulting in significant improvements in minimizing peak current, reducing energy consumption, and preventing mechanical failures. The research followed a systematic process, starting with material selection and procurement, followed by conceptual design, fabrication, and testing. The final system was tested under two configurations: direct circuit and inverter circuit. Results demonstrated that the inverter configuration significantly reduced the peak current from 8 amperes to 2 amperes and the running current from 1.5 amperes to 0.4 amperes, showcasing the system’s economic and operational benefits. The design also includes a PCB layout for optimized power regulation using PWM and IGBT modules. This study provides a practical solution to energy inefficiencies and operational instabilities in water-pumping systems and lays a strong foundation for future innovations in motor control technologies. Recommendations for improvement include integrating advanced algorithms, real-time monitoring, and user-friendly interfaces to expand the system’s adaptability and performance.
