Abstract
An ironless AC linear motor for generating a thrust such that a carrier can move relative to a stator along a movement axis, includes parallel rows of permanent magnets arranged along the movement axis with a given magnet pitch to form a magnetic gap, a row of ironless coils having through holes and a manifold connected to the cooling tubes for distributing the coolant having a length equal to the magnet pitch in the direction of the movement axis.
