Description

Technical Field

[0001] The present disclosure specifically discloses a technical field of inductors, and in particular relates to an automatic winding and shaping device for inductors. Background Art

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, and it only blocks the change of current. If there is no current flowing through the inductor, it will try to block the current from flowing through it when the circuit is connected. If there is current flowing through the inductor, it will try to maintain the current unchanged when the circuit is disconnected. Inductors are also called chokes, reactors, and dynamic reactors.
