Here you have the first of a series of articles where the construction of a Newman's engine.
The author, as on many other occasions, is Jorge Rebolledo. I have never heard of this type of engine, let's see what we can learn ...
How to make a Newman motor
Engine parts or components.
- Circular base
- Methacrylate supports
- axis of rotation
- neodymium magnets
- magnetic wire
We will give 7 turns of magnetic wire to our motor.
Two neodymium magnets are placed in parallel, using a plastic washer cut in half. They are tightly coupled to each other to the axis of rotation.
Side view of engine, counterweight. Magnets A and B will have a special mission in another part of the project
We will continue with the other parts shortly. But to end a video of the engine running
And we leave a video of the engine running
- El Magnetic switch It is placed in front of the engine, as indicated in the photo, this makes the engine work. connects and disconnects the current very quickly.
- Do not forget to place an ACE neon bulb to protect your transistor
- The outlet is 12 volts, and the movement of the magnets generates a huge magnetic field, generating little current consumption and giving an additional benefit. Returns the voltage for you to charge your batteries, even those of your car.
- This is a beautiful engine. A good project for your school or a great personal challenge.
We build 2 small coils of very fine magnetic wire and join the two, leaving two ends (positive * and negative -)
We add a current rectifier to the circuit. The voltage obtained was 29V, which we lowered to 12V with a zener diode.
Use as a magnetic current generator
The motor generates current with magnets A and B (image), when the shaft rotates, it passes at high speed through the magnets, producing electrical energy.
The LEDs are protected by resistors.
The engine is almost perfect,
- consumes very little energy,
- does not heat up,
- makes no noise,
- is a current generatore, charge batteries
- and it is excellent to display at home demonstrating your talent.
It is not something that is practical because it is big. In my case, what mattered most to me was what I learned during the construction process ...
Here you have a video where it shows how it works.
