[VERSATILE APPLICATIONS] Ideal for science projects, physics learning, and teacher demos. 4. [EDUCATIONAL TOOL] Helps students grasp motor structure, rotation principles, and more. 5. [CLASSROOM SAFE] Low power consumption and suitable for AC/DC circuits in educational settings. Specification: Item Type: Electric Motor Model Material: PVC Application: The 24018 small electric motor model is an essential teaching and experimental instrument for high schools, which can be used for both AC and DC circuits. Its main purpose is to familiarize students with the main structure of the motor after disassembly and assembly. Verify the relationship between armature rotation and the direction of current and magnetic lines of force. Master the rotation principle of electric motor operation. Main Technical Performance: 1. The permanent magnet size is 22 x 20 x 20mm / 0.87 x 0.79 x 0.79in (approx.), with a magnetic induction strength of Br not less than 72mT. The N pole is painted red, and the S pole is painted blue or white. The end face should be ground flat. 2. The electromagnetic iron coil should be flat and marked with winding direction. The coil should be multi stranded flexible wire, with red at one end and blue at the other end. The front end should be welded with a wiring fork. How to Use: 1. Assemble according to the diagram. 2. Connect the assembled and adjusted motor to the power supply: A. When conducting a DC motor experiment, connect the 3V‑6V DC voltage to the two terminals, that is, operate normally, and the speed increases with the voltage. If it does not rotate, you can adjust it with your fingers. B. When conducting experiments on DC motors, an excitation coil is used between the two pole shoes to replace a permanent magnet, and its function is completely the same. C. Before connecting to the power supply, it is important to avoid connecting the two brushes to the same commutator to avoid short circuits. D. The permanent magnet N pole is red, while the S pole is white or blue. Pay attention to the color during installation. packing list: 1 xElectric Motor Model
