3. 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.

4. Glue magnets to the rotor with the letter ‘S’ facing outside (or dimple facing inside
depending on magnet marking). If you want to try 2 magnets first, glue them to the
opposite sides.
5. If you want your rotor look better, you may cut out the white glossy round labels that are
provided and paste them to the magnets. It is recommended to use regular white glue or a
glue stick on the labels for better results. This step is optional and may be done after you
finish your motor.

6. Assemble rotor on the base plate. Try to spin it by hand. If it does not spin freely you might
need to squeeze blue bricks slightly together to push plastic shaft sleeves 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 drop of oil from your car dipstick, WD-40, or even vegetable oil.
7. Slide the 1x2 brick with two holes on the electromagnet core to the mark as shown.
If the brick is loose you may use super glue to prevent it from sliding while making the
electromagnet.
The position of the brick is important. It defines the length of the electromagnet. If it is too
long it will not fit; if it is too short the motor will be less powerful or will not work at all.
Mark on the core should be OK but you may find more precise position by checking it on the
board as shown below.
Spin the rotor and make sure that none of the magnets hits the electromagnet!

8. Measure at least 5” (13 cm) of the wire and fold it.
9. Tape the folded end and wind all the wire in one rotational direction (either clockwise or
counterclockwise) moving back and forth along the core. All spool wire should be used.

10.When there is about 5” (13 cm) of wire left, secure it with a cable tie.
11.Remove the insulation from the wire tips with fine sandpaper (included) or a sharp knife.
12.Assemble electromagnet on the base plate.

13.Attach the battery holder to the base plate.
14.Insert the battery and briefly connect electromagnet wires to the battery. If nothing
happens switch the wires. With the correct connection electromagnet repels the permanent
magnets and the rotor stops in the position shown.
15.After you found the correct connection trim red (positive) wire from the battery holder and
corresponding electromagnet wire. Remove the insulation from the wire tips and twist them
together. You may tack this connection under the battery holder.

16.Fasten the reed switch to 1x2 brick with side holes using cable ties. Trim them with scissors.
17.Assemble the reed switch on the base plate. Trim the wires as necessary and remove at
least 1” (2.5 cm) of insulation.
18.Wind bare wire ends tightly around the reed switch contacts.

19.If the head of the electromagnet is lower than the rotor axle you may add small 1x1 brick
as shown to have a better alignment. It also provides additional support for the
electromagnet.
You may tape the electromagnet wire that is connected to the reed switch to the side of the
rotor stand (clear tape is shown).
Spin the rotor by hand. Make sure it does not hit the electromagnet, reed switch or wires.
You should hear the click every time the magnet passes the reed switch.
Your motor is ready! If it does not start on its own you may need to give it a slight push.
Generally if your battery is fresh it should start rotating without the push if you find the
correct position of the electromagnet and the magnets on the rotor sides are centered.
You may glue bricks together and to the plate if you do not plan to disassemble it.
