Tamiya 70222 Friction Power Unit Hands-On STEM Module  [70222]

Tamiya 70222 Friction Power Unit for Demonstrations

The Tamiya 70222 Friction Power Unit is a useful addition for club workshops and classroom kits that need a simple mechanical motion source. It encourages practical learning by letting users construct and test moving assemblies.

Mechanics Behind the Unit

This unit uses a flywheel to store kinetic energy when the drive wheel is turned, transferring that energy via a shaft to crank wheels and other linkages. The clear ABS case provides a direct view of gears and moving parts for learning and inspection.

Integration with Educational Kits

Engineered to work with Tamiya Educational Construction Series components, the friction power unit can attach to plates, beams, wheels and tracks to form functional models. Fit the supplied crank wheels or optional rear wheels such as the Slim Tire Set (Item 70193) to create mobile demonstrations.

Best Uses for Teaching and Prototyping

Use the unit to illustrate motion, force and energy transfer through hands-on builds. Its visible operation and straightforward assembly make it a reliable choice for instructors and hobbyists experimenting with mechanical systems.
