Abstract

In the case of a choke coil (1) having limbs (7a, 7b) which are produced from radially layered laminates and carry windings (9a, 9b), in order to improve the guidance of the stray flux at the connecting points between the limbs (7a, 7b) and the yoke (5a, 5b), a radially layered laminate stack (11a to 11d) is arranged at the connecting points. The radial extent of the laminate stacks (11a to 11b) is greater than that of the respective limb (7a, 7b). In a preferred embodiment, the laminate stacks (11a to 11d) are constructed in the form of circular discs and are in each case arranged between the limbs (7a, 7b) and yoke (5a, 5b). <IMAGE>
