Simple Motors Kit 12 Assembly Instructions Manual
Assembly Instructions: Kit #12
Rapid Assembly Basic QuikLock
Reed Switch Motor
1. Insert the motor shaft through the holes in two 2x2 rotor pieces as shown*. Center the
shaft.
2. Add plastic sleeves (washers) to both ends of the shaft. They fit tightly and require some
effort. You may put the sleeve on the table and push the shaft in with the negative end of
the battery. Leave a small gap so the sleeves are slightly above the surface of the knobs.

If you notice burrs on the plastic sleeves remove them with a sharp knife.

3. Attach double sided sticky pads to the magnets. It does not matter to which side you attach
them as long as you use the same po le for all magnets. This is very important! If you do
not use the same pole for all magnets your motor will not work.
The easiest way to achieve it is to attach the pad to the top of the stack and then move top
magnet to the bottom; after you attach all four pads your stack should look as shown. Do
not remove the second liner from the pads yet.
Neodymium magnets used in this motor are very strong! Be very careful – if they are
allowed to fly to each other they may shatter.
4. Attach all four magnets to the rotor. Try to be accurate and center them on each side. Make
sure there is no gap between the plastic halves.

5. If you assembled the motor properly and lubricated the axle this motor on 1.5 Vo lts battery
may rotate with the speed up to 2600 RPM or even faster. This is really fast but may not be
fast enough for magnets to lose the a dhesion and break the reed switch or fly off the rotor.
However as a precaution you may add a safety ring that completely eliminates this
possibility. This step is optional for your first experiments with the motor, but we strongly
recommend adding the ring later.
The ri ng fits tightly and requires some effort. After centering the ring squeeze the rotor
halves together to make sure that there is no gap between them.
6. Assemble rotor on the base plate. Try to spin it by hand. If it does not sp in freely you might
need to squeeze blue bricks slightly together to push plastic shaft slee ves in. There should
be a tiny gap between sleeves and inner sides of the bricks with holes.
We strongly recommend lubricating the shaft ends. It allows the motor to run smoother and
faster. You may use a small drop of oil from your car dipstick, WD-40, or even vegetable oil.
