Abstract

An exemplary arrangement includes blocks arranged between the inner winding, the individual barriers and the outer winding in order to maintain defined spacing's along the circumference. At least two coils are arranged axially one above the other on a common core limb. Each coil has at least two windings arranged radially one above the other and barriers are provided between the windings. The barriers of adjacent coils are radially offset with respect to one another, and the edge regions of the barriers engage one another in a comb-like manner.

Claims (6)

1. An arrangement comprising:

at least two coils arranged axially adjacent and one above the other on a winding axis of a common core limb,

wherein each coil has a respective set of windings, wherein each set has two windings arranged radially one above the other along the winding axis and respective barriers are provided between the windings, and

wherein the respective barriers of the axially adjacent coils extend lengthwise along the winding axis, are spaced apart from one another, are radially offset with respect to one another, and at edge regions located on adjacent ends of the respective barriers of the adjacent coils, the respective barriers overlap lengthwise along the winding axis such that the edge regions are directly adjacent and engage one another in a comb-like manner.

2. The arrangement as claimed in claim 1 , wherein the respective barriers are wound into the coil and therefore automatically follow a shape of the coil.

3. The arrangement as claimed in claim 1 , wherein the respective barriers are designed as pre-formed components, in each case matched to a shape and dimensions of the coil.
