This model uses the same basic assembly as the motor, but is mounted on a baseplate 230 x 90 mm approx.
which also carries a hand-drive pulley 120mm.
diameter coupled to the smaller dynamo pulley by a rubber belt to give a step-up ration.
Electrical output is via a pair of 4mm sockets.
The model may also be used as a motor on a 6-8 V D.C. supply.
For use with a large motor/generator and a lamp unit to demonstrate the conversion of electrical energy to kinetic energy and then back again.
Comprising an iron flywheel, mounted in cast brackets with bearings.
The shaft has an aluminium 'V' pulley for driving with the spring belt supplied.
Represents internal structure and operating principles of an air-cooled two-stroke engine.
All parts in aluminium alloy.
Ignition is shown by means of a miniature bulb.
Carburetter and fuel supply also sectioned.
Mounted on metal base.
For showing potential energy in a wound-up spring and its conversion to electrical energy by driving a dynamo and lighting a lamp.
May also be used to wind up a weight on a cord showing the change from potential energy to kinetic and back to potential in the raised weight.
The steel shaft carries a clock spring with a free wheel device and winding ratchet, also an aluminium 'V' pulley 56 mm.
diameter.
One end of the shaft overhangs the base for use as line shaft when winding up a weight.
Dimensions 220 x 100 x 100 mm.
high Supplied complete with driving belt.
