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 supply. Discrete devices are divided into bipolar junction transistors, field-effect transistors, thyristors, semiconductor resistors and capacitors. shi

INGEOPAVA electrical components function

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 that can reliably switch 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 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 needed 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). At the beginning, the pull-in coil and 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, so it can 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, special attention must be paid to the design quality of the solenoid switch.

INGEOPAVA electrical components structure

Inductors are generally composed of bobbins, windings, shielding covers, encapsulation materials, magnetic cores or iron cores, etc. 1, Bobbin: The bobbin refers to the support for winding the coil. Most large-volume fixed inductors or adjustable inductors (such as oscillator coils, choke coils, etc.) are made by winding enameled wire (or silk-covered wire) around the bobbin, and then inserting magnetic cores, copper cores, or iron cores into the inner cavity of the bobbin to increase their inductance. Bobbins are usually made of plastic, bakelite, or ceramic, and can be made into different shapes according to actual needs. Small inductors (such as color-coded inductors) generally do not use bobbins, but directly wind enameled wire around 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 magnetic cores, bobbins, or shielding covers. Instead, they are wound on a mold first, then the mold is removed, and a certain distance is maintained between each turn of the coil. 2, Winding: The winding refers to a set of coils with specified functions, which is the basic component of an inductor. Windings are divided into single-layer and multi-layer types. Single-layer windings have two forms: close-wound (wires are wound circle by circle) and spaced-wound (a certain distance is kept between each turn of wire during winding); multi-layer windings include layered flat winding, random winding, honeycomb winding, etc. 3, Magnetic Core and Magnetic Rod: Magnetic cores and magnetic rods are generally made of nickel-zinc ferrite or manganese-zinc ferrite materials, and come in various shapes such as "I" shape, cylindrical, cap-shaped, "E" shape, pot shape, etc. 4, Iron Core: Iron core materials mainly include silicon steel sheets, permalloy, etc., and their shapes are mostly "E" type. 5, Shielding Cover: To prevent the magnetic field generated by some inductors during operation from affecting the normal operation of other circuits and components, a metal shielding cover is added (such as the oscillator coil of a semiconductor radio). Inductors with shielding covers will increase coil loss, reducing the Q value. 14, Encapsulation Material: Some inductors (such as color-coded inductors, color-ring inductors, etc.) are sealed with encapsulation materials after winding to enclose the coil and magnetic core. Encapsulation materials include plastic or epoxy resin, etc.
