DynaMot generator


To fulfil the special requirements of the proposed experiments the generator has the following specifications:
When operated manually the short-circuit proof generator can produce a voltage of up to 8 V. At an easily by students obtainable speed the produced voltage will be 3 to 4 V so that the most usual bulbs can be operated without burn out.
Generator, gear box and power transmission have been constructed with such a stability that even when operated in a short circuit mode no mechanical damage will occur. The maximum load of approx. 10 A faces no problem for the device. The generator allows energy conversion which needs physiologically clearly perceptible driving power in the range of 2 to 60 W (short circuit). Nevertheless the friction is so little, that changes in energy consumption of 2 W can be realized when turning the crank.
The DynaMot consists of an electric motor with flanged, low noise gearing box, housed in a transparent Plexiglas case with 4 mm socket terminals, crank and pulley, interchangeable, mounted on square section, nickel-plated steel rod.
