MAIN PURPOSE: This instrument is used by schools to scientifically demonstrate the working principle of generator, demonstrating that mechanical energy can be converted into electrical energy.<br/>2. WORKING PRINCIPLE: The armature rotor is rotated in a permanent magnetic field to generate current. When the hand wheel rotates to drive the armature rotor, the current is generated in the coil to make the LED light.<br/>3. COMPOSITION PARTS: The instrument is composed of base, armature, pole shoe, magnetic field, brush, hand wheel, and load plate, etc., with a compact structure, easy connection and operation.<br/>4. STURDY MATERIALS: The hand crank generator is made of excellent PVC and other materials, which has good toughness, high strength, large resistance, ensuring a longer service life.<br/>5. APPLICABLE SCENES: This hand generator is suitable for physics teaching in middle and high schools, electronic experiments, etc., provides a clear and intuitive demonstration process.<p><br/></p><p><b>Specification:</b></p>Item Type: Hand Crank Generator<br/>Material: PVC<br/>Use: This instrument is used for school scientific demonstration of the working principle of the generator, indicating that the mechanical energy can be converted into electric energy.<br/>Construction: The generator uses an armature rotor to rotate in a permanent magnetic field to generate current. The instrument is composed of base, armature, pole shoe, magnetic field, brush, hand wheel and load plate. The two ends of the armature coil are respectively connected to 2 copper rings, copper ring type flow collection and reversing linkage device. When the hand wheel rotates to turn the armature rotor, a current is generated in the coil to make the LED light.<br/><p><br/></p><p><b>How to Use:</b></p>When in use, the size of the belt pulley is set up with the belt, and the brush is in good contact with the collector half ring. By turning the crank the big pulley turns the armature and then one diode lights up, changes the direction of rotation, and the other diode lights up. Thus, it can be shown that a current is generated in the coil, and the mechanical energy is converted into electrical energy.<p><br/></p><p><b>Package List:</b></p>1 x Hand Crank Generator</div><br/> <p style="margin-bottom:6px; margin-top:6px;"> </p> <p><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><!--#list--><!--#if--></p><div style=" margin-bottom:6px; margin-top:6px;"> </div> <p style="margin-bottom: 6px"></p> <p>Many Questions about Dropshipping Services Are As Follows:</p> <p>1.How many orders can you handle per day?<br/> we are a large company in Shenzhen,China,with a large warehouse that can handle large orders everyday.We send out countless parcels everyday.We can guarantee the order you request.</p> <p>2.How fast can you process orders?<br/> We will arrange shipment as soon as possible after you pay the order.Priority delivery for dropshipping order</p> <p>3.Could you ship order without any receipts,invoices and promotional offer inside the package?<br/> Absolutely!No invoices,receipts,promotional offer if you leave notes on the order(if you want,we can provide.)</p> <p>4.If you need other products?<br/> We can provide most products you need as much as possible1</p> <p>If you have any other questions,please feel free to contact us.<br/> We are very grateful to cooperate with you.</p> <p>5.We can support CSV/Excel File Dropshipping.</p> <p>6.There is no limite</p></div></div></div></div>
