Set 103: standard Lego® motor (4.5V - 1969 - 1975)

The next Lego® motor (set 103) was brought out only 3 years later in 1969. It has an height of 3 1/3 and came in colours blue and black again, but it has had the big advantage to become repaired very easiely. It has a housing which is closed with 4 screws: two on top and two in the bottom. The housing has still three connection points in shape of a pair of studs. Two of them on the very top. A improved batteriebox (still with contacts at the bottom side) could directy be attached there.

By adding an spare 12V motor one could upgrade set 103 from battery use to transformator use. Same couple was sold as set 702. The first sliding contacts (set 704) have had contacts made out of kid of chromed steel. And their contacts to the motor side have had the shape of a fir tree: even their position on top of the 2x4x1 brick became changed later...

The battery box of 103 opens to the top and is somewhat smaller than the later ones: battery size has grown somewhen during the seventies! But with AA type rechargable batteries you can drive these motors very cheap and without problems.

There have been some different kind of cables during the early 70ies: single plugs, coupled plugs, contacts made by metal shets and massive contacts either. The colour of the cables has always been white, the colour of the plug always blue, exept from set 118/138, where highly rare red plugs are used. + 12V, 1969 - 1975)
