面励磁構造の可動電機子型リニア直流モータ。 A stationary side field magnet is formed by having P (P is an integer of 2 or more) magnetic poles of N and S poles so that magnetic poles arranged adjacent to each other along the moving direction of the mover have different polarities. A coreless armature is disposed on the traveling yoke of the mover facing each side of the side field magnet to form a movable side coreless armature, and the traveling yoke on which the movable side coreless armature is disposed is arranged in the moving direction of the mover. When one end of the fixed side field magnet faces a substantially boundary between the N pole or the S pole of the fixed side field magnet, the other end faces substantially the center of the N pole or S pole of the fixed side field magnet. The double-sided excitation structure is characterized in that the two running yokes arranged on both sides are arranged with a phase shift of approximately one-fourth of the magnetic pole width from each other in the running direction of the slider. moving armature linear DC motor.
