Stirling Engine with Generator and LED Diode Functional Model of Hot Air Engine 16.5 x 8.5 cm Aluminium and Quartz Glass Physics Experiment
You already have the maximum available quantity in your cart.
The functional model of the Stirling engine with a generator demonstrates the entire process from heat through motion to electricity. The externally combusting engine stands on a base made of aluminium alloy and its hot cylinder is formed by a tube made of quartz glass, which is heated by the flame of an alcohol burner. After about a minute of heating, a gentle spin of the flywheel is enough to start the engine, which then drives a small generator via a belt, lighting up the LED diode. This model is suitable for physics experiments at school and at home, for technology enthusiasts, and as a gift for collectors of mechanical models. The construction is metallic, silver, and disassemblable.
The principle of the Stirling engine lies in the heating and cooling of enclosed air. The warm air in the glass cylinder expands and pushes on the piston of the working cylinder, which rotates the flywheel with a diameter of 49.43 mm via a connecting rod. The flywheel, through the movement of the other piston, shifts the air back into the cooler part, where it contracts, and the cycle repeats continuously. The pulley on the flywheel transfers the rotations via a belt to the generator, so the illuminated diode clearly demonstrates that electrical energy is generated from heat. The mechanism is open, allowing a clear view of the movement of the pistons, connecting rods, flywheel, and belt.

- Contents of the package – Stirling engine model on aluminium base with generator and LED diode and alcohol burner without fuel
Before the first use, turn the flywheel by hand and check that it spins easily and smoothly, and ensure that the sliding parts are clean. Fill the burner no more than two-thirds full and position the flame towards the front of the glass tube. With the generator connected, heating takes slightly longer than with the model without it. It is advisable to occasionally lubricate both ends of the connecting rod, but the piston itself should not be lubricated. During operation, do not touch the heated tube or the metal parts connected to it, and be careful that the wick of the burner does not touch the glass.
The Stirling engine with generator is suitable for anyone who wants to see the transformation of heat into motion and electricity in one model. The aluminium base, glass cylinder, and metal parts make it a tool that stands up in a school laboratory as well as on a work desk. The generator lights up the LED diode without batteries, with energy supplied solely by the flame of the burner. It is suitable for students, physics teachers, and technical enthusiasts, and is intended for users aged 14 years and above. As a gift, it will delight anyone who enjoys mechanics, electricity, and experiments.
