how to make the electricity generator using dc motor

In this article we show you how to make the electricity generator using dc motor | working model | inspire award science project

Creating an electricity generator using two DC motors, where one acts as a generator, is a great way to understand the basic principles of electricity generation.

Here’s a step-by-step guide to help you build this model:

Materials Needed:

  • 2 DC motors
  • 9V battery
  • Battery clip with leads
  • LED light
  • Wires
  • Alligator clips (optional, for easier connections)
  • Tape or glue
  • Cardboard (for mounting the components)
  • Scissors or craft knife
  • Soldering iron (optional, for secure connections)
  • Small plastic gears (optional, for better motor coupling)

  1. Prepare the Base Structure:
    • Cut the Base: Cut a piece of cardboard to serve as the base for your model. A piece about 12 inches by 6 inches should work well.
    • Mount the Motors: Attach the two DC motors to the base using tape or glue. Position them so that their shafts are aligned and can be connected. If you have plastic gears, attach one to each motor shaft to mesh them together.
  2. Connect the Motor Shafts:
    • Direct Coupling: If you don’t have gears, you can connect the shafts directly using a small piece of rubber tubing or a flexible connector.
    • Ensure Connection: Make sure the connection between the motor shafts is secure, allowing one motor to drive the other.
  3. Wiring the Motors:
    • Motor 1 (Driver): Connect the leads of the 9V battery to the terminals of the first DC motor. This motor will act as the driver, converting electrical energy from the battery into mechanical energy.
    • Motor 2 (Generator): Connect the output terminals of the second DC motor to the leads of the LED light. This motor will act as the generator, converting the mechanical energy back into electrical energy.
  4. Secure Connections:
    • Alligator Clips: Use alligator clips to make the connections between the motors, battery, and LED light if you have them. This makes it easier to adjust connections.
    • Tape or Solder: Ensure the wires are securely connected. You can use tape for a temporary setup or solder the wires for a more permanent and reliable connection.
  5. Test the Generator:
    • Power the Driver Motor: Attach the 9V battery to the first motor (driver). This motor should start spinning, driving the second motor through the connected shafts.
    • Observe the LED: As the second motor (generator) spins, it should generate electricity, causing the LED light to illuminate.

Explanation of the Science:

  • DC Motor as Generator: A DC motor can function as a generator when its shaft is spun, producing electricity due to electromagnetic induction.
  • Energy Conversion: The first motor converts electrical energy from the battery into mechanical energy. This mechanical energy is transferred to the second motor, which converts it back into electrical energy to light the LED.
