摘要

1/1 summary “electromagnetic actuator, particularly for needle-selection devices in wide-gauge knitting, knit or similar sewing machines” an electromagnetic actuator, particularly for needle-selection devices for sewing knit or similar articles with wide gauge. The electromagnetic actuator (1) according to the invention includes a main magnet (2) having at least two polar regions (3a, 4a; 3b, 4b) which are arranged side by side and separated by a gap (5a; 5b). . the electromagnetic actuator (1) includes two selection electromagnets (6, 7) each having at least one polar region (6a, 6b; 7a, 7b) that is aligned with the gap (5a; 5b) and laterally spaced from such a gap (5a; 5b). at least one polar region (6a, 6b) of one selection electromagnet (6) is laterally disposed opposite the at least one polar region (7a, 7b) of the other selection electromagnet (7) with respect to the gap (5a) 5b). The selection electromagnets (6, 7) can be activated individually to generate or cancel or reduce a magnetic force of attraction in the corresponding polar region (6a, 6b, 7a, 7b).
