Product overview This permanent magnet rotatable armature generator is designed for hands on teaching of the basic structure and working principle of AC and DC generators in junior school physics and elementary school natural knowledge classes. The unit combines visible internal components with manual operation to demonstrate generator behavior and output characteristics. Key benefits Clear demonstration of generator principles: Visible stator, rotor, brushes and pole components make the electromagnetic and mechanical interactions easy to observe and explain. Practical classroom output: Produces measurable voltages at typical manual speeds, allowing students to perform noload and loaded experiments with realistic values. Simple operation and inspection: Manual mechanism and exposed components let instructors adjust rotor speed and explain effects of load and speed on voltage. Durable permanent magnet design: Twopiece barium constant magnetic material magnet assembly provides stable pole orientation and is arranged to improve conversion rates. Main features and specifications Function: Teaching instrument for the structure and working principle of AC and DC generators in junior and elementary school natural knowledge education. Construction: Permanent magnet rotatable armature generator composed of stator, rotor, brushes, base plate and manual mechanism. Magnet assembly: Two pieces of barium constant magnetic material; red marks N pole and blue marks S pole; includes pole whip to assist magnetic pole formation and improve conversion rates. Performance: At rotor speed 1200 to 1600 rpm the generator delivers a noload voltage of at least 6 V. Under a load of 0.3 A the output voltage is at least 3 V. Operation: Manual drive mechanism allows controlled rotor speed and direct observation of brush and commutator action. Practical applications and use scenarios Classroom demonstration: Use in physics lessons to show how rotor motion and magnetic poles produce alternating or direct current, and to demonstrate the role of brushes and commutator. Laboratory experiment: Students can measure voltage versus speed and load, compare noload and loaded outputs, and analyze generator efficiency and behavior. Student projects and science fairs: Suitable for experiments that require a tangible generator model to explain electromagnetic induction and basic electrical measurement. What is included and user guidance Visible components include stator, rotor, brushes, base plate and a manual rotation mechanism for hands on manipulation. Magnet configuration is provided as two barium constant magnetic material pieces with color coded poles for easy identification. Recommended operation range is 1200 to 1600 rpm for representative voltage outputs; measure voltages under noload and with a 0.3 A load to verify performance. Why choose this unit for teaching Specifically designed for educational settings to translate theoretical concepts into observable phenomena. Reliable permanent magnet construction and clear pole marking make it straightforward for instructors and students to follow causal relationships between motion, magnetic field, and electrical output. Compact manual operation supports classroom demonstration without need for external power sources.
