DIY Dynamo Lantern Educational Building model, Labs Demonstration Motor Activity Teaching Model Hand Cranked Power Electricity DC Electric Generator Physical Science Experiment Education - Hand Powered Specification: Item Name: DIY Hand crank generator model Size: 173 * 88 * 118mm \ 6.81 *3.46 * 4.64 in (L * W * H) Material: plastic and metal Color: Multicolor (White \ Red \ Yellow \ Green) How to Use: When using, use a belt to wrap the pulley and make the brush in good contact with the collecting half ring. Rotating the large pulley through the rocker drives the armature to rotate. At this time, one LED emits light, changing the direction of rotation, and the other LED emits light. It can be explained that a current is generated in the coil, and mechanical energyis converted into electric energy. Pay Attention: 1. The wire and the collector ring and the LED soldering area should not be touched by hand to prevent the line from being disconnected. 2. After the experiment is completed, the belt sleeve should be removed on one wheel to prevent the belt from being loose and slippery.
