The Malvern Energy Transfer Kit comprises a number of separately available units which enable the user to show qualitatively energy conversion from one form of energy to another in a variety of different ways. This unit is for use as a driving unit/dynamo. It consists of a 2 to 6V DC motor provided with a 15mm diameter 'V' pulley and driving belt. All units have a base measurement of 165mm x 100mm and have 4mm socket terminals where appropriate.
