Hint M4 - Blue battery motor

The K’NEX Battery motor is an electric motor which includes an integral 3v power pack. The power pack has a three-way switch allowing the motor to be run in either direction. It takes two AA batteries (not supplied).

Please note that in most K'NEX sets this Battery motor is now supplied rather than the older, more difficult to use, "Tethered motor" - see Hint M2. Both battery motors are very good for models where you don’t need the motor to turn a rod very fast, but you do need quite a lot of power, such as a Bulldozer or Ferris wheel.

A number of the larger K'NEX sets include K'NEX battery motors. They can also be bought as individual items in our Technology 2 enjoy K'NEX shop.

To use the Battery motor, simply push a rod (quite hard) through the hole in the middle. Experiment by turning on the switch on the battery pack to turn the rod in each direction.

The easiest way to attach the motor to your model is to fit a white connector onto the lugs at each side of the motor, as shown in the photo opposite.

Finally, read Hint L6 if you want to make your battery motor turn wheels or connectors.

The photo opposite shows a battery motor connected into a vehicle.

We would particularly recommend the battery motor rather than the tethered battery motor for a K'NEX model such as this, as there are no trailing cables.
