Electric 'LEGO' Motor
As the beakman motor have no torque at all, I decided to buil this project based on the design of the regular electric motors. With a medium difficulty, this motor is able to work with a fair load using 6 volts. (2/7/2007)Category: lego science projects diy homemade howto - Updated: 2009/07/24
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)Category: science projects homemade diy lego howto - Updated: 2009/07/24
