Product overview This handcranked generator uses a permanent magnet to create the magnetic field required for armature rotation. It is built from a stator, rotor, brushes, bottom plate, and a manual drive mechanism, and illustrates both AC and DC generator principles in a single unit. Key features and functions Permanent magnet design: provides a stable magnetic field for clear demonstration of electromagnetic induction. Complete mechanical assembly: includes stator, rotor, brush assembly, bottom plate, manual mechanism, collector ring, and slip ring with copper halfrings. AC and DC outputs: AC output is taken through the collector ring and brushes. Moving the brushes to the middle of the slip ring, where the copper halfring is rectified, produces DC output. Ready to use: unit is preassembled. After delivery, install the pulley and adjust the brush position to begin experiments and demonstrations. Manual operation: handcranked design converts kinetic energy into electrical output, allowing direct observation of the relationship between mechanical input and electrical output. Why this product is useful Handson learning: makes abstract electromagnetic concepts tangible by allowing students to see and control rotor motion, brush contact, and output type. Demonstrates conversion and control: shows how brush position and commutation change output from AC to DC, reinforcing lessons on generators and circuits. Clear component visibility: exposed stator, rotor, and brush parts make internal generator structure easy to examine and explain. Compatibility, materials, and performance notes Components included: stator, rotor, brushes, bottom plate, manual mechanism, collector ring, slip ring, and copper halfring rectifier elements. Output behavior: AC delivered via collector ring and brushes; DC obtained by relocating brushes to the slip ring mid position where the copper halfring acts to rectify the output. Setup: minimal installation required. Install pulley and finetune brush position to optimize electrical output and conversion efficiency. Practical applications School physics classes: demonstration of basic structure and working principles of AC and DC generators for junior physics and elementary natural science lessons. Laboratory and classroom experiments: use for controlled experiments on generator behavior, commutation, and energy conversion. Science fairs and hobby projects: a reliable teaching aid for student projects and maker activities exploring electricity generation and mechanicaltoelectrical energy transfer. How to use Mount the unit and install the pulley. Turn the manual crank to rotate the rotor and observe AC output via the collector ring and brushes. Move and adjust the brushes to the slip ring mid position to produce DC output and study the effects of brush positioning on voltage and waveform. This generator provides a practical, handson way to study generator mechanics, commutation, and the conversion of kinetic energy into electrical energy without additional components.
