DEFINITION

Classification: 336/214

(under the class definition) Inductor devices comprising inductor core structure with more than one independent and distinct closed loop of magnetic material, the loops forming closed magnetic circuits adapted to thread through and about the coil means of the inductor.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5+, for similar structures limited by claimed subject matter to polyphase inductor structure.

83, for inductors wherein the coil means is totally enclosed within the core means, except for openings for the coil leads.

155+, particularly 160+, for inductors of the saturable or high leakage reactance type having cores with multiple magnetic paths.

184, for inductors with plural coil windings wherein the coils may be on different core legs. 211, for inductors with concentric or nested core elements which may form separate magnetic loops.

212, for inductors having plural part cores, e.g., separate preformed leg and yoke members forming separate magnetic loops.

213, for inductors having a core comprising separate loops each formed of wound magnetic material.
