Controllable inductor |
摘要 |
A controllable inductor including at least one tubular core (10), a main winding (5) surrounding the core and a control winding (11) running substantially axially through said core and returning substantially axially outside thereof between said core and said main winding. The control winding is divided into a plurality of separate part control windings (12). The cross section of the part control windings is formed in a way that at least some adjacent part control windings inside the core are separated by means of a spacing (20, 26), which is at least partly defined by substantially parallel surfaces (16, 17) of these part control windings.
