Abstract
The invention relates to a linear motor for a device for testing a printed circuit board. The linear motor comprises a stator and a rotor, wherein the stator comprises a row of permanent magnets arranged side by side and alternating in their polarity, and wherein the rotor is formed from a printed circuit board on which conductor paths form magnet coils arranged side by side and each having several windings, which magnet coils, when carrying a current, apply a linear acceleration force to the rotor, so that the rotor is moved relative to the stator, wherein the printed circuit board is folded, so that the several windings of each magnet coil are distributed among several layers of the printed circuit board, which are placed on top of one another by folding the printed circuit board.
