Fixed inductors are components used in various electrical and electronic circuits for stabilizing, filtering, tuning, impedance matching, coupling and decoding pulses. They are mostly used to pass AC while blocking DC, and blocking AC while passing DC. Low-power inductors are often referred to as chokes, and high-power inductors are called reactors. The SD7030-100-R belongs to the latter group and is mainly used in the field of electric power.

A SD7030-100-R is a type of fixed inductor known as a reactor, which finds its application in power supplies, scooters, electric cars, turbines, robots, medical equipment, HVAC/R, renewable energy systems, motor control systems and motion control. It consists of an iron core wound by a copper wire and varnish. The copper wire allows electricity to move through but stores energy in the form of a magnetic field when not in use.

In terms of its working principle, the SD7030-100-R operates like any other inductor: An alternating current is forced through the copper wire, creating an electromagnetic field. As this field expands and contracts, it induces a voltage in the wire. This voltage opposes the current, which causes energy to be stored in the form of a magnetic field. As the current flow stops, this energy is released as the magnetic field collapses, producing a current in the opposite direction. This characteristic, called inductive reactance, is what gives the SD7030-100-R its functionality.

As the electric current moves through the SD7030-100-R, it also creates an outward or inward directed magnetic field, depending on the current\'s direction. This magnetic field can be used for various applications, such as sensing, for various devices such as smart home appliances, etc. For instance, many washing machines use a motor with an inductor to regulate speed, and a motion controller in a robotic arm could employ an inductor to maintain position.

In addition, the SD7030-100-R is also used in power supplies, as energy is stored in the inductor for the use of other components. In this application, the SD7030-100-R acts as a filter by reducing the amount of noise and other high-frequency signals. In plasma cutting and welding, the inductor also serves the purpose of high-frequency components by providing the power during the cutting/welding process.

Due to its wide application in electric power engineering, SD7030-100-R reactors are used in almost every power supply from small AC adaptors to large distributed energy systems. They are essential components in the efficient operation of motors, relays, regulators, and other powerful equipment.

In conclusion, the SD7030-100-R is a fixed inductor belonging to the reactors category, which finds its application in electric power systems. It works by the production of an opposing voltage created by the magnetic field caused by current. It is mainly used to filter noise, and regulate electric motors, relays, regulators, and other machinery. Thus, it is a very important component in many industries.
