Demonstration Dynamo
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.
