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)
