METHOD OF RESIN MOLDING CORELESS LINEAR MOTOR ARMATURE, CORELESS LINEAR MOTOR ARMATURE, CORELESS LINEAR MOTOR, AND TABLE FEED APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a method of resin molding a coreless linear motor armature, a coreless linear motor armature, a coreless linear motor, and a table feed apparatus, which reduce an increase in the temperature of an armature coil unit while securing the insulation distance between a coil of the armature coil unit and a mount to which the coil is mounted, and ensure moldability to provide a quality resin mold for the armature.;SOLUTION: According to the coreless linear motor armature, a gap between a recession 8a of the armature mount 8 and an upper side 11 of a coil group of the armature coil unit 7 is filled with a first resin mold 20, and a second resin mold 21 having heat conductivity smaller than that of the first resin mold 20 is applied to cover the under surface of the recession 8a of the armature mount 8 and the periphery of the armature coil unit 7. Hence the armature mount 8 and the armature coil unit 7 are integrally molded.;COPYRIGHT: (C)2010,JPO&INPIT
