Description

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.

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.
