摘要: A platen used as a stator of a planar linear motor having a platen body (90) comprised of a stacked member (91) of magnetic sheets (T) giving a high performance and a backing plate. The backing plate of the stacked member (91) is formed with dovetail grooves (91a) along a direction perpendicular to the sheet edge direction. The backing plate (92) has a plurality of first through holes (92a) discretely arranged in lines longitudinally across the strip-shaped portions facing the dovetail grooves (91a). Top bent side ends (94) of connecting beam members (93) have pluralities of second through holes (94a) discretely arranged in lines longitudinally across the beam longitudinal direction. Joints (100) of a fluid hardening material injected into the dovetail grooves (91a) and the through holes (94a) (92a) to fill and harden in the same are formed. The joints (100) are comprised of molded connecting parts (101) filling and fastening the dovetail grooves (91a) and molded joining parts (102) connected to the same, filling the through holes (94a) and (92a), and holding together the backing plate (92) and the top bend side ends (94).

摘要: The invention concerns a stator-excited starter-generator with a permanent-magnet assembly (M) disposed in the axial space between two sector stator elements (SS1; SS2) each excited by an exciter coil (EW1; EW2) of opposite polarity. The direction of magnetization of the permanent-magnet assembly (M) is opposite to that of the coil excitation, and the assembly (M) has yoke projections (J11, J12) extending radially with respect to the respective adjacent sector stator elements (SS1; SS2).

摘要: Using a smooth laminated armature assembly (3), with a ferromagnetic double-helix stator shaft (1), provides an economical radial pole linear reluctance motor requiring no external armature bearings. The stator shaft has a double-helical screw tooth pattern (2,2′) cut into its surface. Spaces between screw threads are preferably filled with low permeability material (6). The armature assembly has radial pole laminar plates (4), separated by identically configured laminar spacers (7), separated by an insulating layer (8), which provides eddy current isolation, physical stability and original adjustment of laminations for overall accuracy to linear positioning, despite tolerances in the individual laminar plates. Each laminar plate has a number of inwardly projecting teeth centered about the internal channel. These internal teeth and the double helix screw teeth on the stator shaft provide flux paths through the stator. The armature assembly and the stator are complementary, and smoothed for sliding contact within the electromagnetically active envelope, without other bearings. Linear placement of radial pole laminar plates is achieved by dimensioning the radial pole laminar plates and/or the laminar spacers slightly less in thickness than nominal spacing requires, filling the space with epoxy, and pressing the end laminations together to nominal total length. Excess epoxy is squeezed out, leaving the laminations evenly spaced. Stator and armature may be assembled, or may be prepared with virtual teeth in homogeneous smooth surfaces. The virtual teeth are prepared by ferromagnetic modification of selected patterns through laser hardening or through chemical doping.
