WIPO Patent Application WO/2021/038728
Kind Code:
A1
Abstract:
This linear motor system (1) comprises: a mover (50) that has a plurality of permanent magnets (52) disposed in the advancing direction in planes parallel to surfaces formed in the advancing direction and the vertical direction; and a stator (200) that has an armature (20) that includes an iron core in which a plurality of protruding parts to which a coil is wound are disposed in the advancing direction, the armature (20) being disposed so as to face the permanent magnets (52) of the mover (50). The mover (50) comprises: a mover body part (51a) that has a first main roller (57) that engages with a first travel surface (26a) disposed on the stator (200); a placement base unit (55) on which an item to be conveyed is placed; and a sub-roller (62) that engages with a second travel surface (29a) disposed on the upper surface of the stator (200). The first main roller (57) supports the magnetic attraction generated between the stator (200) and the mover (50), and the sub-roller (62) supports a force in the reverse direction of the magnetic attraction, the force acting on the mover (50).
