Linear Piston for a Magnetic Repulsion Electric Generator.

thingiverse

This is a linear piston that will be used in a Magnetic Electric Generator project. The goal is to create a Magnetic Repulsion Piston that uses 1/2 inch N50 grade Neodymium Cylindrical Magnets to move linearly through a set of coils and generate Voltage and Current. One preliminary test produced 7.2V DC with an output current of 1.0 Amps at 1300 RPM passing the piston through 3 Magnet Wire Coils that were 1/4 inch wide with 25 Feet of Magnet Wire wrapped around each Coil. The Linear Piston does not have to move far, about 1.25 inches back and forth through the 3 Magnet Wire Coils. For each revolution of the drive wheel, the repulsion piston will induce 6 power pulses inside of each individual coil. Since the magnets are 1/2 inch long, the North Pole is approximately 1/4 inch long, and the South Pole is approximately 1/4 inch long. A good starting point is to make sure the air gap between the two magnetic poles facing each other in a repulsion configuration are spaced 1/4 inches apart. This produces good results. If you think of the magnetic field lines as a traveling wavefront, you can try different coil wrapping techniques to study how they respond when a magnetic field is moving through them. A piece of magnetic film is useful to see the magnetic field lines in the repulsion area of the linear piston. KS Metals sales brass tubing in 12 inch lengths that can be found at ACE Hardware stores. I got a 1/2 inch diameter tube to hold the 1/2 Neodymium Magnets. The 17/32 inch diameter brass tube was used to wrap the magnet wire coils around. The 1/2 brass tube will slide back and forth inside the 17/32 brass tube. The distance between the surface of magnets to the start of the magnet wire in the coils is around 45.25 thousandths of an inch. A light machine oil should be applied between the brass tubes to reduce friction. The closer you can get the magnet wire coils to the surface of the magnets, the stronger the magnetic field will be, which will produce more Voltage and Current at a specific RPM. I am trying to use 3D printing to build a small desktop version that gets close to these same results. These parts were designed using the Freeware Version of the EMachineShop software.
