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.
