A table fan working model is a simple project that demonstrates how an electric motor works to convert electrical energy into mechanical energy, resulting in airflow.
This project is ideal for explaining the basic principles of electricity and mechanics.
Key Components of the Model:
- Base and Frame: The structure, often made of cardboard or plastic, supports the fan blades and motor. This mimics the body of a real table fan.
- Electric Motor: The core component that drives the fan blades by converting electrical energy into mechanical energy.
- Fan Blades: These are made from lightweight materials like cardboard or plastic. The blades are attached to the motor shaft and are responsible for generating airflow.
- Power Source: A battery or a DC power supply is used to provide electricity to the motor.
- Switch: A small switch is included to turn the fan on and off, demonstrating how electrical circuits are controlled.
- Wiring: Thin wires connect the battery, switch, and motor, completing the electrical circuit.
How It Works(Table fan working model):
- Power Supply: When the switch is turned on, electricity from the battery flows through the circuit to the motor.
- Motor Function: The electric motor uses electromagnetic principles to create rotational motion. Inside the motor, an electromagnet interacts with a permanent magnet to spin the motor shaft.
- Blade Movement: The motor shaft rotates, causing the attached fan blades to spin rapidly. The angled blades push air forward, creating a cooling effect.
- Air Circulation: The spinning blades generate airflow, mimicking the function of a real table fan.
Applications and Learning:
- Demonstrates Principles: The model shows how electrical energy is transformed into mechanical energy.
- Educational Value: It helps explain the functioning of motors, circuits, and the basics of airflow.
- Practical Understanding: Students learn about energy conversion, simple circuits, and mechanical design.
This table fan model is a practical and interactive way to understand electric motors and their real-life applications.
