- Function and design: The motor is an induction-based device that electrifies via electrostatic induction. The electric brush is designed for user-friendly operation, with copper wire mounted on a spring to perform friction tests. This setup reduces abrasion on the electrifying plate and the conductive layer, providing a longer service life. - Size and frame: Starting plate diameter options are 235 mm and 260 mm. The electrostatic induction motor is mounted on a plastic frame for stable, lightweight use. - Conductive layer durability: The machine’s conductive plate features a conductive coating that is firm and long lasting, supporting repeated experiments with reliable performance. - Use value: This equipment serves as a practical physical laboratory aid, suitable for use in teaching demonstrations or as a decorative display in a lab, helping physical experiment learning become more efficient. - Use scenarios: - In a physics classroom, demonstrate electrostatic induction and friction effects with a clear, durable setup. - During lab demonstrations, illustrate wear reduction from the spring-mounted copper wire and the durable conductive coating. - On a bench as an educational display that reinforces physics concepts while remaining functional.
