This model uses the same basic assembly as the electric motor, mounted on a base plate which also carries a hand drive pulley 120 mm in diameter coupled to the smaller dynamo pulley by a rubber belt. Electric output is via a pair of 4 mm socket & a light emitting diode is provided as simple output indicator. The model may also be used as motor on a 4 to 8 volts DC supply.

A simple demonstration of a Dynamo Model mounted on a wooden base. Hand driven by a gear. Simplified open frame construction which can be readily understood without detriments to its essential similarity to real machine. A 2 pole armature wound by enamelled copper wire to rotate in U shape magnet in pivot. While in rotation process through the gear wheel by hand, the bulb provided glows.

A model of the simplest form of DC motor; having 3 armatures - 2 pole, 3 pole, & 4 pole, wound with enamelled copper wire, & a permanent magnetic field provided by a removable bar magnet. The construction is completely open & all components are readily observable. A disc type commutator is incorporated & external connection to the phosphor - bronze bushes is by means of a pair of 4 mm sockets. The motor shall operate on 4.5 to 9 volts DC.
