Claim Text:
1. An apparatus comprising: a linear motor disposed to generate a linear force, the linear motor including: an armature coil disposed within an internal housing, a magnetic core associated with the armature coil, an upper gap separating the armature coil from a top of the internal housing, a lower gap separating the armature coil from a bottom of the internal housing, and side gaps separating the armature coil from the internal housing; and a fan configured to cause air to flow in the upper gap, the lower gap, and side gaps, along a length of the armature coil in a direction parallel to the linear force, wherein the armature coil is a first armature coil and the magnetic core is a first magnetic core, the apparatus further comprising: a second armature coil adjacent to the first armature coil, the first armature coil separated from the second armature coil by a first coil gap; a second magnetic core associated with the second armature coil, wherein the fan is configured to cause air to flow in the first coil gap, wherein a size of the upper gap, the side gaps and the lower gap are selected to cause turbulent air flow in the upper gap, the lower gap, and side gaps; and a central support core extending from the top of the internal housing to the bottom of the internal housing.
