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.
To show the forces which can be exerted during thermal expansion or contraction.
Comprising a heavy cast iron frame 340x120x100mm with slotted end pillars to carry a stout iron bar.
The bar is threaded at one end for a large tensioning nut and has holes at the other end to accommodate the cast iron breaking bars.
Supplied complete with ten breaking bars.
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 56 mm.
diameter, and the other end is fitted with a cord anchoring collar.
Supplied complete with driving belt.
A model of the simplest form of D.C. electric motor, having 2-pole armature wound with enamelled copper wire and a permanent magnetic field provided by a removable bar magnet.
A disc-type commutator is incorporated and external connection to the phosphor-bronze bushes is by means of a pair of 4 mm. sockets.
The motor will operates on 6-8 Volts D.C.
To show conversion of mechanical energy into electrical energy.
Turbine with transparent cover, inlet and outlet tubes, directly connected to a dynamo. Fitted on base.
For use with motor/generator to give an indication of their output when used as dynamos.
The lamp-holders are connected in parallel.
Supplied with three lamps 3.5 V 0.25 A, M.E.S.
