A Fly-Wheel Unit
For use with a large motor/generator and a lamp unit to demonstrate the conversion of electric energy to kinetic energy and then back again. Comprising of an iron flywheel 115mm dia. mass 1.2kg, mounted in cast brackets with bearings. The shaft has an aluminum ‘V’ pulley 44mm dia.
for driving with belt supplied.
B Lamp Unit, Triple
For use with motor/generators to give an indication of their output when used as dynamos. The lamp holders are connected in parallel. Supplied with three lamps 3.5V 0.25A, M.E.S.
C Large Motor/Generator
For use as a driving unit or dynamo. Comprises a 2 to 6 V D.C. motor provided with a 15mm dia. ‘V’ pulley. Supplied with belt.
D Small Motor/Generator
For use with the larger motor/generator in comparing power input and output by driving each unit in turn with the other and metering the voltages and currents.
E Line Shaft Unit
For showing the conversion from electrical energy, via mechanical to potential energy by winding up a weight on a cord. One end of the 6mm steel shaft carries an aluminium ‘V’ pulley 56mm dia. and the end is fitted with a cord anchoring collar. Supplied with belt.
F Turbine/Pump Unit
For use as a water turbine to drive a generator producing electricity or for use as a pump driven by a motor and raising a head of water to produce potential energy. The rotor has 8 bucket blades and is housed in a block turbine chamber 50x50x25mm, with a clear Perspex front. Two
inlet tubules (for turbine and pump operation respectively) and one outlet tubule are provided, and the shaft carries a 15mm dia pulley. With driving belt.
G Spring Unit
For showing potential energy in a wound up spring and its conversion to electric 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 unit also has a ‘V’ pulley 56mm dia. dimensions 220 x100 x100mm high complete with driving belt.
H Head Of Water Unit
For use with turbine pump unit to provide an open or closed system in demonstrating the conversion from electrical to kinetic energy in the pump and potential energy in the head of water. Complete with two 80mm dia basins and shaped glass tubes. The upper platform has 38mm dia hole to allow use as a simple circulation system.
I Hand Wheel Driving Unit
For use in driving dynamos, line shafts, flywheels etc. The driving out pulleys are both 75mm dia. and the intermediate pulley is 20mm dia. giving a step up ratio of 3.75.
J Mounted Lamp 12V 24W
A 12V 24W S.B.C. bulb in a metal socket mounted on a folded metal base 100 x 63mm with a pair of 4mm sockets.
K Mounted Solar Cell
For use with the motor to demonstrate the production of electrical energy directly from light energy. The apparatus comprises of a selenium photo voltic cell housed in a plastic case with diffusing lens.
L Mounted Motor For Solar Cell
This is a small low consumption electric motor on a base specially designed to run directly from the output of the solar cell.
