Core for a controllable inductor and a method for producing therof |
摘要 |
A tubular core (6) for a controllable inductor with a main winding (1) surrounding the core and a control winding (7) passing substantially axially through the core. The core (6) is capable of receiving a magnetic flux from the main winding (1) running substantially axially therethrough and having a plurality of core rings (8) stacked co-axially on top of each other and connected to a rigid unit. The core rings (8) are connected to each other forming a walled construction. The core (6) also has an inner envelope (18) with an outer cross-section that is substantially equal to the inner cross-section of the core ring walled construction. The walled construction has joints (16) between the core rings (8) in an axial direction which are overlapped by a part of the envelope (18).
