LEGO® 4.5V Reversible Power Unit

Description

A drive rather than a model

This set is not a vehicle but a drive unit: the motor ran on 4.5 volts and, as the name says, could be reversed. Red, blue, light grey and black are the colours, and of the 24 pieces, 9 are different. The motor was meant to power constructions of your own or train models. There are no minifigures. Such motors drove trains and vehicles of your own, without having to buy a complete model with them.

For collectors and technical fans

Seen today, the set is a piece of early electrical technology in the system and of interest to collectors of the Samsonite era. The parts list on this page shows which bricks and housing parts are included. The basic bricks combine with other elements, even though the drive technology of the time is long outdated. If you only use the parts as bricks, you get small plates and bricks in four colours.

FAQ

How many pieces does the Power Unit 107-3 have?

What does reversible mean?

The motor can run in both directions, so a model driven by it can go forwards and backwards.
