Abstract
A linear motor includes a magnet plate including magnets arranged side by side in a first direction, a slider configured to slide in the first direction, and a cooling pipe provided at a surface portion. Grooves and ridges alternate in the first direction. The grooves are elongated in a second direction that is parallel to a surface of the magnet plate and orthogonal to the first direction. The ridges are elongated in the second direction. The cooling pipe is routed to wind back and forth through the grooves. On a side in the second direction, a first end portion of each of the ridges is entirely located inward of two end faces in the second direction, or a portion of the first end portion, excluding a central portion of the first end portion, is located inward of the two end faces of the slider in the second direction.
