アモータ。[Claims for Utility Model Registration] (1) A plurality of permanent magnets are arranged such that adjacent magnetic poles have different polarities, and the different poles face each other with an air gap between them, and a multi-phase coil is installed in this air gap. What is claimed is: 1. A linear motor comprising a movable element movable in the direction in which the permanent magnets are disposed, characterized in that an end surface of the permanent magnet parallel to the moving direction of the movable element is formed into a concave surface. (2) The linear motor according to claim (1), wherein the concave surface is a cylindrical curved surface.
