Abstract
A linear motor device includes a track member with multiple magnets with alternating N poles and S poles arranged along the moving direction, and a moving body with a configuration which includes an armature which is movably mounted on the track member; and the device generates a driving force in the moving direction between the magnetic flux created armature and the magnets of track member. The armature also includes a heat conduction member arranged in cooling passages formed in cores of the armature. By this, coils on the moving body side are cooled efficiently, and a large driving force can be achieved by passing a large current as well as maintaining a large space for winding the coils in order to increase the winding count.
