Electric 'LEGO' Motor II
As the previous motor is not easy to build and it doesn't have too much torque, I decided to improve the design. This motor is more like "Pulse Motor" as it pushes the magnets with only one coil. With only 3 Volts, it have three times more torque that the previous one and is easier to build. (2/9/2007)

I had to glue the magnets together with the same polarity on the same side (see photo)


A reed switch is activated by a magnetic field, so, it needs to be on the exact location where the magnets may turn it when the coil needs to be pushed.
I glued the reed switch to a LEGO piece and tried it.



I'm sure with two coils this motor will be fully functional. The coil was made with copper wire #30 AWG, about 40 to 50 turns.
WARNING: Neodimium magnets are dangerous. It may break and the pieces may fly away at high speeds, also it may pinch/crush your fingers as it as it may stick together because the strong magnetic field.
