Abstract

This study aimed to enhance students' scientific understanding and creative thinking through experiments designed to explore the operating principles and performance of electric motors. Electric motors are essential components widely used in various electronic devices and machinery in households and industries. They are also key topics in middle school science curricula. However, students often lack a deep understanding of the internal structure of electric motors. To address this, this study conducted experiments measuring the revolutions per minute (RPM), disassembling electric motors, and evaluating the strength of their magnets. The results showed that higher RPM values indicated better motor performance, with a strong correlation between magnet strength and motor efficiency. In the experiment involving the creation of simple electric motors, it was observed that increasing the strength of the magnets and the number of wire coils led to faster rotational speeds. Students gained a deeper understanding of the structure and principles of electric motors through activities involving disassembly and performance comparisons. These activities were confirmed to have educational benefits, fostering interest in real-world applications and enhancing their engagement with the subject matter.
