摘要： A stator assembly (10) has a pair of end holes (12a, 16a) leading to a hollow region (14a) which has a larger diameter than the end holes (12a, 16a). The assembly (10) is manufactured around an elongated pole (22) having a diameter equal to the end holes (12a, 16a), which is surrounded by a temporary sleeve (24) whose thickness fills the gap between the pole (22) and the inner wall of the hollow region (14a). The pieces of the assembly (10) are placed onto the pole (22) such that the sleeve (24) lies within the hollow region (14a), to thereby align them correctly with one another. After the pieces are secured to each other, the pole (22) is removed, leaving the sleeve (24) within the hollow region (14a), and then the sleeve (24) is removed (24). The sleeve (24) may be flexible in order to expedite is removal from the hollow (14a), and also may be of a magnetic material (17) that is kept in place by magnetic forces generated by the stator assembly (10) or by the pole (22).

摘要： An interlocking assembly of a voice coil motor for a hard disk drive having an arcuate shaped hollow structure fortmed by metal injection molding. The hollow structure has a bottom plate member that is separated from a top plate member by a pair of upright members disposed therebetween. The upright members joined with the inside surfaces of the plate members. The uprights are disposed at each end of the hollow structure. A tapered recess is formed in the top surface of the bottom plate, the recess ingress's from a convex edge of the bottom plate and narrows while extending through to an opposite concave edge, the tapered recess has side edges shaped to tightly interlock with a flat arcuate shaped permanent magnet having dovetail side edges to slidely interlock with the tapered recess of the bottom plate of the hollow structure, thus eliminating the need for adhesive fastening.

摘要： The invention concerns an elongate stator for a linear motor with grooves (2) and elastically deformable electrical leads (3) which are to be secured therein. The groove walls (6) are open towards the exterior by means of slots (7) which, at their narrowest point, are narrower than the outer diameter (d) of the leads (3). Owing to their elastic deformability, the leads (3) can be pushed through the slots (7) into the grooves (2) and secured therein.

摘要： A low frequency vibrator has a stator member (10) with a cylindrical, central chamber (12), a cylindrical, tubular liner of low friction, non-ferromagnetic material (18) positioned in the chamber (12) to form a bearing, and a cylindrical, ferromagnetic, reciprocating piston (20) slidably mounted in the liner (18). The stator (10) has a pair of coils (30, 32) and a permanent magnet (44) is positioned centrally in the reciprocating piston (20). A ferromagnetic flux conductor surrounds the coils (30, 32) and extends between opposite ends of the chamber (12). This structure creates a magnetic spring, having a spring constant K. The ratio of K to the mass M of the reciprocating piston (20) is made substantially equal to the square of a radian frequency in the operating frequency range of the vibrator.

摘要： A synchronous twin reciprocating piston apparatus includes a cylinder (12) and a number of stator assemblies (14) mounted in fixed relation thereto. The stator assemblies (14) are constructed so as to generate a radial magnetic field in a number of regions (16) near to each end of the cylinder (12). The apparatus also includes a pair of piston-magnet assemblies (18), each having a piston (20) slidable within an end of the cylinder (12), and a number of compound permanent magnet systems (22) located within the regions (16). Each compound permanent magnet system (22) includes a first section (34) magnetized in a direction radial relative to the cylinder axis and a second section (36), axially displaced from the first, magnetized in the opposite direction. When the stator assemblies (14) are excited with an alternating current, the piston-magnet assemblies (18) reciprocate axially relative to said cylinder (12), and synchronously with the frequency of the applied current. The pistons (18) then generate a pulsating pressure within the cylinder (12).

摘要： An electromagnetic actuator (10) is disclosed having a ferromagnetic case (12) and defining a central axis with a slidable core (16) disposed coaxial with the central axis. The core includes first end (20), second end (22) and core (24) portions. The actuator (10) further includes a magnetic flux developing element (18) mounted coaxial with the central axis and first and second ferromagnetic electrical coils (14). The first and second coils (14) are mounted in a facing relationship with the first (20) and second (22) end portions of the core (16). The coils (14) have a cross-sectional length in a direction perpendicular to the central axis and a width of insulating space between the turns of the coils (14) in a direction parallel to the central axis. The length and width are selected such that the reluctance of the width of the insulating space is greater than the reluctance of the cross-sectional length of the coil wire adjacent the insulating space.

摘要： An electromagnetic actuator (50) includes a magnetic flux conductive case (52), an electric coil (54), a magnetic flux conductive material core (56), and a pair of radially polarized magnetic flux developing elements (58, 60). A first region (80) of the core (56) traverses the coil (54) at one end and second region of the core (56) traverses the coil (54) at the other end. A first magnetic element (58) is carried by the first region (80) and a second magnetic element (60) is carried by the second region (82) so that magnetic flux across the coil between the first region (80) and the case (52) is in a first direction, and magnetic flux across the coil between the second region and the case (52) is in a second direction. The coil (54) is arranged so that an electrical current in the coil at one end flows in an opposite direction with respect to the direction of the current at the other end.
