Manufacturing process of a closed electromagnetic mass accelerator
The device is a disk made of dielectric material with a closed groove designed to roll the ball in a circle. 4 induction coils are placed in it at the same distance from each other, through which the ball moves. Each solenoid operates pulsed. At the moment the pulse is applied, an electromagnetic field is created, which “pulls” the ball into itself with acceleration.As it moves, the field is turned off, so the braking effect that appears when passing the center of the solenoid, when the projectile begins to be attracted back, is not created. Thus, the first coil attracts the ball towards itself, gives it acceleration and then it is intercepted by the next solenoid, and so on ad infinitum.
Assembling the device must begin by making a disk with a groove. It provides 4 seats for coils, taking into account the distance for installing control boards. The disk can be cut out of plywood using CNC, but it is best to print it on a 3D printer.
4 coils for winding wire are also manufactured.
Next, in an accessible way, you need to make 4 round printed circuit boards along the diameter of the coils from foil fiberglass and etch tracks on them, as in the photo.
The boards are then drilled.
Transistors, resistors and LEDs as in the photo.
Assembly must be carried out extremely carefully; the long legs of the parts on the back of the boards are bitten off so that they do not interfere with further assembly.
Next, 0.4 mm wire is wound onto the coils, 300 coils each. Then half rings are glued onto the printed circuit boards, which are necessary to connect the gaps in the trench at the location where the coils are installed.
Printed circuit boards are connected to each other in series. Then the ends of the solenoid windings are soldered into them. After this, the boards are glued to the side of the coils.
The connected coils are inserted into the seats on the disk and aligned so that the glued half-rings close the gap in the groove track.
Now, when power is applied to the solenoids, and an iron ball is forced to roll through any of them, it will begin to circle at high speed along the chute.
