The construction is very simple and is basically based on the idea of Lasersaber pulse motors , which have probably achieved the best results in terms of low power consumption. I am pleased that this motor gives comparable results to its, although it is made of old ready-made materials in a very short time.
As you can see on the picture the schematic is very simple. All eight coils are connected in series. The reed switch is also connected in series with coils.
t is very important that the success of the device very much depends on the position of this reed switch And it is determined experimentally depending on the model of the reed switch. Extremely low consumption is due to the design as well as the way the axle is set. In fact, one end of the axle floats using a small magnet so that friction is minimal. This motor can also operate without a reed switch, with the help of a circuit consisting of two transistors and one variable resistor. By changing the resistance of the potentiometer, the current through the coils changes, and thus the speed of rotation of the motor.
In the video that follows you can see how all the modes of operation of the engine work, as well as a detailed description of its construction.
Very cool thing to have sitting on your bench/desk. Especially since it can run form solar. Although running it from a potato is a fantastic party trick!
