Abstract
An electromagnetic moving system comprises a stator, a moving body and a controller. The stator comprises a circuit board with two layers of electrically connected coil windings spaced apart in a series way and made as spirals with center and peripheral points. The spirals of one layer are shifted in respect to the spirals of the adjacent layer along the line connecting the center points thus the center points of the spirals of one layer in transparent view are located between two nearest spirals of the adjacent layer. Each of the spirals of one layer in transparent view at least partially overlaps two nearest spirals of the adjacent layer. The moving body is comprised of one permanent magnet such as to cause interaction with the stator when it is powered, thus creating a force tending to propel the moving body along the line connecting said center points.
