Abstract
A linear motor for short strokes includes a primary section including a coil brace and coils disposed in it, as well as a secondary section that is movable relative to the primary section and has magnet holders with magnets placed on both sides of the coil brace. Spacers separate the magnet holders from each other such that the coil brace is movable between the two magnet holders. The spacers are guided through openings in the primary section.
