リニア電動機

Japanese Patent JP5404029

B2

A linear motor is configured by including an outer permanent magnet row (11) configured by arranging arcuate permanent magnets to be adjacent to each other in a manner that magnetic poles of the permanent magnets are rotated by 90 degrees at most to each other of the permanent magnets in a cross-section including center axes of the permanent magnets, a field magnet including an inner permanent magnet row (15) having magnetization vectors whose radial directional components are directed in the same directions as those of the outer permanent magnet row (11), and whose axial directional components are directed in directions opposite to those of the outer permanent magnet row (11), an armature including a three-phase coil (31) shaped like a ring, which is supported between the outer permanent magnet row (11) and the inner permanent magnet row (15) so as to be movable in an axial direction of the ring, and a driving device (9) which causes the armature to generate a predetermined thrust. In this manner, strong magnetic fluxes can be linked with an armature coil without using an iron core, and magnetic fluxes of the field magnet are linked with the whole armature coil.
