摘要： Disclosed herein is a linear d.c. motor comprising a field magnet composed of plural magnetic poles, and an armature formed by arranging armature coils along the moving direction of a moving element at a position facing the field magnet. One of the field magnet and armature is attached to the moving element, and the other is provided on a stator yoke serving as a stator. Projecting edges for linear guide, each of which projects outside and has a triangular form in cross section, are provided on both sides of the stator yoke, and guide rollers, each of which has an engaging groove in the form of a valley in its side part coming into slidable contact with the projecting edge for linear guide, are attached to the moving element. There is no possibility that the moving element is derailed because it is supported by the projecting edges of linear guide and the guide rollers. It is therefore possible to make the thrust of the moving element greater and cause it to travel at high speed.
