Claims

[Claims for Utility Model Registration] In the armature structure of a linear motor in which a spacer is provided between a coil housed in a slot in an armature core and an opening side of the slot, the spacer is made of a heat-resistant insulating material. What is claimed is: 1. An armature structure for a linear motor, comprising a protrusion and a tapered part on both sides thereof, the tapered part being in close contact with the slope of the slot.
