Title:
CYLINDRICAL LINEAR MOTOR ARMATURE, CYLINDRICAL LINEAR MOTOR FIELD POLE, AND CYLINDRICAL LINEAR MOTOR USING THEM
Document Type and Number:
WIPO Patent Application WO/2008/013053
Kind Code:
A1
Abstract:
It is possible to provide a cylindrical linear motor capable of solving the problem that a leak flux links an aluminum frame at the both ends of the armature of a conventional cylindrical linear motor, which causes a viscous braking force as a motor brake force. A cylindrical linear motor armature (20) includes a plurality of cylindrical coils (20a) arranged in the axial direction inside a cylindrical yoke (20b) formed by a magnetic material and frames (20d, 20e) covering outside of the cylindrical yoke (20b). Only in the axial direction region where the cylindrical yoke (20b) exists, the frame (20d) is formed by aluminum and the both ends in the axial direction of the armature is formed by a resin cap (20e).
