A regenerative energy working model using two DC motors, a 9V battery, a switch, and toy car wheels can demonstrate how mechanical energy is converted into electrical energy and then reused.
This model gives a practical demonstration of regenerative energy by recycling some of the energy from a mechanical system into electrical energy!
Here’s how you can create this model:
Materials Needed:
- 2 DC motors (one as a generator, one as a motor)
- 9V battery
- Switch (to control the flow of electricity)
- 2 toy car wheels
- Connecting wires
- Cardboard or wooden base (for mounting)
Video Steps to Build the Model:
1. Prepare the Base:
- Create a sturdy cardboard or wooden base to mount the components.
- Attach the two DC motors securely to the base, keeping them apart from each other.
2. Attach Wheels to the Motors:
- Fix one toy wheel to the shaft of each DC motor.
- Ensure the wheels are tightly secured and can spin freely.
3. Wiring the Motor to the Battery:
- Connect one of the DC motors (Motor A) to the 9V battery. This motor will act as the drive motor.
- Insert a switch between the battery and the motor so you can control when the motor runs.
4. Connect the Second Motor as a Generator:
- Wire the second motor (Motor B), which will act as a generator, to the first motor (Motor A).
- The output terminals of Motor B (generator) can either be connected back to recharge the battery or to another small load (like an LED) to show electricity generation.
5. How It Works:
- When you flip the switch, the 9V battery powers Motor A, which spins the toy wheel.
- The spinning wheel is attached to Motor B, and as Motor A drives the wheel, Motor B also spins when we bring near to Motor A
- Motor B acts as a generator here, converting the mechanical motion from the spinning wheel into electrical energy.
- The electricity generated by Motor B can be sent back to the battery (regenerative effect) or used to power something else, like lighting up an LED.
Regenerative Effect:
- Motor A (drive motor) consumes battery power to rotate the wheel.
- Motor B (generator) captures the rotational energy and converts it into electrical energy.
