Fixed Inductors

S1008-103F Application Field and Working Principle

Fixed inductors, or chokes, are electrical components used to store and control the flow of electrical energy in circuits. This type of inductor is designed to perform the same basic function as a variable inductor, but with the added capability of providing precise control over the amount of energy stored in the circuit. By regulating the flow of energy in a circuit, engineers can create more efficient and reliable designs in a number of different applications.The S1008-103F fixed inductor is designed to provide precise control over the power consumption on variable-frequency drives. This drive is activated when the main frequency output of alternating current motors varies. Adjusting the current through an inductor allows engineers to control the output power in this drive and therefore effectively regulate the motor’s speed of operation.The S1008-103F is an efficient, cost-effective and reliable fixed inductor. It offers engineers a number of useful features. The low differential line inductance and high insulation resistance of this inductor make it particularly suitable for oscillating and switching applications. The S1008-103F also has a very low core losses, enabling engineers to maintain a low heat output when using this inductor in their designs.The working principle of fixed inductors is similar to that of transformers. When electrical current passes through the winding of a fixed inductor, it produces both an electromotive force (EMF) and an inductance. The EMF pushes against the existing current in the circuit, requiring the operator to reduce the amount of energy flowing through the coil. The inductance creates an opposing force that counters changes in the amount of current, ensuring that the fixed inductor does not let too much energy become available in a circuit.In addition to regulation, fixed inductors are used in switching applications to perform one distinct switching operation: the switching of an electrical relay. When an electrical current passes through the winding of a fixed inductor, it produces a magnetic field. This magnetic field interacts with the current passing through the electrical relay’s contacts, causing them to open or close when desired. This switching operation is used in a large number of applications, such as circuit breakers, switchgear, automatic door locks, and even in home automation.Fixed inductors are also used in high-voltage grounding systems. When electrical current passes through a fixed inductor it creates a local electric field which helps to protect people and equipment connected to the circuit from harm. This safety feature is particularly important in high-voltage applications because the stored energy can discharge suddenly and cause injury or damage.The S1008-103F fixed inductor is an invaluable tool for engineers looking to control the power on variable-frequency drives. With its low differential line inductance, high insulation resistance and low core losses, this inductor provides an efficient and reliable way to regulate the power output of a motor in a wide variety of applications. Furthermore, by understanding the working principle of fixed inductors, engineers can also use them in a variety of other applications, including relay switching and high-voltage grounding systems.
