INGEOPAVA electrical components Germany INGEOPAVA model INGEOPAVA price

INGEOPAVA electrical components are products whose raw material molecular composition is not changed during factory processing, and can be called components. Components belong to devices that do not require energy. They include: resistors, capacitors, inductors. Circuit-type components include diodes and resistors; connection-type components include connectors, sockets, connecting cables, printed circuit boards (PCB), etc. Devices are products whose raw material molecular structure is changed during factory production and processing. Devices are divided into active devices and discrete devices. The main characteristic of active devices is that they consume electrical energy and require an external power source. Discrete devices are divided into bipolar junction transistors, field-effect transistors, thyristors, semiconductor resistors and capacitors. shi

INGEOPAVA electrical component functions

The starter solenoid switch is a key component of the starter motor, and its design quality directly affects the reliability of the starter. The starter solenoid switch has two functions: one is to connect the main circuit to make the starter rotate, and the other is to push out the drive gear via the shift fork to engage with the engine flywheel ring gear. Therefore, the solenoid switch is required to have corresponding suction force, corresponding stroke, and contacts capable of reliably switching high currents. In addition, it is required to minimize volume and weight as much as possible. Based on the above characteristics, the contact structure of the solenoid switch generally adopts a contact form, i.e., the moving contact is made into a bridge shape or a disc shape to provide a larger heat dissipation surface and thermal capacity. The magnetic system mostly adopts a solenoid electromagnet structure to meet the requirements of corresponding stroke, corresponding suction force, small volume, and light weight. The moving iron core of the solenoid switch can move smoothly in the brass bushing equipped with a solenoid coil. The moving iron core pull rod is connected to the shift fork and one-way clutch. Under the action of the return spring, the moving iron core normally remains in the non-working initial position. When starting, the starter drive gear needs to move forward by about 12-24mm. Therefore, when the solenoid switch begins to close, a large magnetomotive force is required to generate the necessary initial suction force. After being pulled in, the air gap decreases, and the electromagnetic suction force increases sharply, greatly exceeding the force required to maintain the closed state. For this reason, the solenoid switch uses two coils (pull-in coil and holding coil). Initially, both the pull-in coil and the holding coil jointly generate electromagnetic suction force. After the switch contacts close, the pull-in coil automatically disengages from the working state, and only the holding coil maintains the switch in the closed state. The holding coil current is relatively small, allowing it to be wound with thinner wire. This not only reduces the volume of the solenoid switch but also achieves reasonable suction force matching. To ensure the reliability of the starter, emphasis must be placed on controlling the design quality of the solenoid switch.

INGEOPAVA electrical component structure

Inductors generally consist of a bobbin, winding, shield, encapsulation material, and magnetic or iron core. 1. Bobbin: The bobbin refers to the support frame for winding the coil. For larger fixed inductors or adjustable inductors (such as oscillator coils and choke coils), enameled wire (or silk-covered wire) is mostly wound around the bobbin, and a magnetic core, copper core, or iron core is inserted into the inner cavity of the bobbin to increase its inductance. Bobbins are usually made of plastic, bakelite, or ceramic, and can be manufactured in different shapes according to actual requirements. Small inductors (such as color-coded inductors) generally do not use a bobbin; instead, the enameled wire is wound directly onto the magnetic core. Air-core inductors (also known as former-less coils or air-core coils, mostly used in high-frequency circuits) do not use a magnetic core, bobbin, or shield. Instead, they are wound on a mold first, then the mold is removed, and a certain distance is maintained between the turns of the coil. 2. Winding: The winding refers to a set of coils with specified functions and is the basic component of an inductor. Windings are classified into single-layer and multi-layer types. Single-layer windings come in two forms: close-wound (where wires are wound turn by turn adjacent to each other) and spaced-wound (where a certain distance is maintained between each turn of wire). Multi-layer windings include layered parallel winding, random winding, and honeycomb winding, among others. 3. Magnetic Core and Magnetic Rod: Magnetic cores and magnetic rods are generally made of materials such as nickel-zinc ferrite or manganese-zinc ferrite. They come in various shapes, including "I" shape, cylindrical, cap-shaped, "E" shape, and pot shape. 4. Iron Core: Iron core materials mainly include silicon steel sheets and permalloy. Their external shape is mostly "E" type. 5. Shield: To prevent the magnetic field generated by some inductors during operation from affecting the normal operation of other circuits and components, a metal shield is added (such as for oscillator coils in semiconductor radios). Using a shield increases coil losses and reduces the Q value. 14. Encapsulation Material: Some inductors (such as color-coded inductors and color-ring inductors) are sealed with encapsulation material after winding to enclose the coil and magnetic core. The encapsulation material consists of plastic or epoxy resin.
