This model uses the same basic assembly as the EDU727N Demonstration Electric Motor except it is mounted on a base plate 230 x 90mm approx. which also carries a hand-drive pulley of 120mm diameter. It is 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 lamp is provided as a simple output indicator. The model may also be used as a motor on 6-8 Volt DC supply.
