Demonstration Dynamo (EE - 679)

This model uses the same basic assembly as the motor, but is mounted on a base plate 230 x 90mm approx., which also carries a hand drive pulley 120mm dia. coupled to the smaller dynamo pulley by a rubber belt to give a step-up ratio. Electrical output is via a pair of 4mm sockets and a light emitting diode is provided as simple output indicator. The model may also be used as a motor on a 6-8V D.C. supply.
