Abstract
An electromechanical device has a coil configuration comprising an insulating substrate (30) carrying a first group of 12 series-connected spiral conductor patterns (21a-21m) and a second group of 12 series-connected spiral conductor patterns (22a-22m). Some of the conductor patterns (21a, 22a, 21d, 22d, 21e, 22e, 21i, 22i, 21j, 22j, 21m and 22m) are disposed on the upper side of the substrate (30). Other ones of the conductor patterns (21b, 22b, 21c, 22c, 21f, 22f, 21h, 22h, 21k, 22k, 21l and 22l) are disposed on the underside of the substrate (30). The conductor patterns on both sides of the substrate (30) are electrically interconnected by means of plated-through connections (40). The first group is in arranged in parallel with the second group by means of common connection electrodes (51 and 52). The conductor patterns (21a-21m) of the first group and the conductor patterns (22a-22m) of the second group are carried by the same substrate (30).
