ARRANGEMENT HAVING AT LEAST TWO COILS WHICH ARE ARRANGED AXIALLY ONE ABOVE THE OTHER ON A COMMON CORE LIMB

摘要

An arrangement is proposed having at least two coils (1, 4) which are arranged axially one above the other on a common core limb (7), wherein each coil has at least two windings (2, 3, 5, 6) which are arranged radially one above the other, and barriers are provided between the windings (2, 3, 5, 6). The barriers (9 - 13, 15 - 19) of adjacent coils (1, 4) are arranged radially offset with respect to one another, and the edge areas of the barriers (9 - 13, 15 - 19) engage in one another like a comb. Alternatively, the barriers (21 - 25, 27 - 31) of the mutually directly opposite areas of adjacent coils (1, 4) are alternately shortened and lengthened, such that a shortened barrier (21, 23, 25) of one coil (1) is always opposite a lengthened barrier (27, 29, 31) of the other coil (4) and, conversely, a lengthened barrier (22, 24) of one coil (1) is opposite a shortened barrier (28, 30) of the other coil (4), and a shortened barrier follows a lengthened barrier in each coil (1, 4). Alternatively, some of the barriers are in the form of isolation rings (34/35, 38/39, 43/44, 47/48) which additionally engage around the end surfaces of the windings (2, 3, 5, 6), which end surfaces are arranged at right angles to the winding axis (W).
