An armature of a linear motor is cooled by a serpentine channel formed in the lower surface thereof and sealed with a sealing plate. In one embodiment, the serpentine channel is formed in a separate cold plate in good thermal contact with laminations of the armature. In another embodiment, the serpentine channel is formed by stacking bundles of laminations having suitably formed notches therein. The bottom of the serpentine channel is sealed with a sealing plate. A sealant layer between the laminations of the serpentine channel prevents coolant leakage from the serpentine channel into the laminations. A sealing interlayer, may be interposed between the surfaces of the lamination bundles and the sealing plate both for sealing against coolant leakage and for affixing the sealing plate in position. The sealant layer and the sealing interlayer may be of the same material and formed at the same time.
