Description:
- Product Name: DIY Dynamo Generator Model Wooden Science Experiment Toys For Children Physics Learning Educational Kits STEM School Projects
- Material: Wood + electronic components
- Size: 12*6*9cm
- Condition: 100% brand new and high quality
Features:
Kids get to learn about principles of electricity through building their very own electric generator. Just turn the handle to make the pullies spin an electric motor and turn on a light.
Working Principle:
The connecting wheels of the large and small transmission wheels increase the engine speed. There are magnets and copper coils inside the generator. The copper coil rotates to cut the magnetic induction line motion, thereby generating an induced current. Light up the small lamp beads by boosting the voltage through the booster board.
Package Include:
- 1 x set of Dynamo Generator Model Kit
Assembly steps:
Step 1: Use white glue to glue the four small squares to the four corners of the board.
Step 2: Use white glue to glue the frame. At this time, the glue is not dry, you need to handle it gently.
Step 3: Connect the whole frame with glue. [Wait 15-20 minutes for the glue to solidify]
Step 4: After the glue has solidified, assemble the transmission shaft and lock it with the yellow sleeve [the small white rotating shaft part faces inward]
Step 5: Install the swing arm and driving wheel, and use the yellow sleeve to lock it.
Step 6: Tie the motor bracket under the inclined beam with a cable tie. [Or put it flat on a wooden board] Install the motor
Step 7: Install the belt, install the short belt on the upper wheel, and connect the long belt to the motor wheel.
Step 8: Fix the USB board with double-sided tape. Connect the red wire to the positive electrode and the black wire to the negative electrode. The assembly is complete. Because the circuit needs a stable current from the start, you should speed it up a few times [or lift the belt a few times] at the beginning to reduce the speed after the light is on.
