Abstract: 1308349 Linear motors INFORMATION MAGNETICS CORP 23 Nov 1970 [8 Dec 1969 22 June 1970] 55582/70 Heading H2A A linear motor, particularly for positioning transducers in a magnetic storage device, comprises a cylindrical permanent magnet 17, Fig. 1, radially polarized, a centre core 16 spaced from the inner surface of the magnet to define a working air gap 18 and connected to the other surface of the magnet by a magnetic circuit including a low reluctance shell 13 surrounding the magnet, and a removable armature coil 19 disposed in the air gap and connected to actuating means. As shown, the core is supported at one end of the shell by a plate 14 which may consist of a plurality of washers, and current is conveyed to the coil by a pair of flexible conductors 33 extending through longitudinal slots 28, 29 in the shell and magnet. The coil 19 may consist of flat aluminium wire 41, Fig. 3, which is edge wound and the turns bonded together by thermosetting plastics material 42. Alternatively two overlapping layers of flat copper wire may be bonded together in plastics material, the layers being connected in parallel, Fig. 4 (not shown). The core 16 may consist of steel or soft iron bars bonded together by epoxy resin or may be of segmental construction, Fig. 6. Disposed in slots 59 between the segments are radial vanes 57 which support the armature coil 56 on a central rod 59 which transmits the movement of the coil. Secured externally of the core 16 in Fig. 1 or internally of the magnet 53 in Fig. 6 is a compensating winding 37, 54 respectively adapted to produce a field opposite to that created by the coil 19 or 56 to prevent distortion of the permanent magnet field by the latter field. Various compensating coil connections and alternative arrangements are illustrated in Figs. 8-13 (not shown).

Luffing tackle pulleys 6, 7 are symmetrically mounted on brackets 13, 14 pivoted on the shaft 17 at 15, 16 on axes parallel to the luffing axis. Movable pulleys 5 are attached by a link 11 to the head of the boom 2 while fixed pulleys 8, 9, 10 are mounted on the shaft 17. Luffing rope 19 passes from the luffing drum 4a in sequence over pulleys 9, 5, 6, 5, 8, 5, 7, 5, 10 and back to the drum 4a.
