Use: Student and demonstration experiments on energy conversion, electric current, voltage, power, and generator and motor principles in physics lessons

With the DynaMot – Hand-Operated Generator, students generate electrical energy using their own muscle power. This provides a hands-on way to understand the relationships between mechanical and electrical energy, voltage, current, power and energy flow.

The integrated 4 mm sockets allow the DynaMot to be connected to lamps, measuring instruments, electric motors and other experimental components. This makes it suitable for experiments on electric circuits, series and parallel circuits, energy conversion, and generator and motor principles.

The generator is driven by a hand crank and a low-noise gearbox with a 30:1 gear ratio. In manual operation, voltages of up to 8 V can be generated. At a rotational speed easily achieved by students, approximately 5 to 6 V can already be reached.

The change in the physical effort required for different electrical loads provides a particularly clear demonstration of the relationship between mechanical energy input and electrical power output. The DynaMot is short-circuit proof and features a transparent acrylic housing, a hand crank and an integrated cord pulley.
