Actual Differential Gear

Description

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.

Description

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.

Description

Highly useful for demonstrating the most fundamental and frequently used mechanism. Very useful for engineering students. All the components are made of high degree of precision. These modules are assembled on transparent perspex sheets to facilitate teaching. Easy to assemble or disassemble.

Description

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 eight 'bucket' blades and is housed in a block turbine chamber 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 15 mm. diameter pulley. With driving belt.
