KONARIKZAVESOVA electrical components Germany KONARIKZAVESOVA model KONARIKZAVESOVA price

KONARIKZAVESOVA electrical components are devices that convert electrical energy into mechanical energy. They utilize energized coils (i.e., stator windings) to generate a rotating magnetic field, which acts on the rotor (such as a squirrel-cage closed aluminum frame) to form electromagnetic rotational torque. Electric motors are classified into DC motors and AC motors based on the power supply used. Most motors in power systems are AC motors, which can be synchronous motors or asynchronous motors (where the speed of the stator magnetic field does not remain synchronized with the rotor rotation speed). An electric motor mainly consists of a stator and a rotor. The direction of motion of a current-carrying conductor under force in a magnetic field is related to the direction of the current and the direction of the magnetic field lines (magnetic field direction). The working principle of an electric motor is that the magnetic field exerts a force on the current, causing the motor to rotate.

KONARIKZAVESOVA electrical component classification

Microphones can be divided into dynamic microphones and condenser microphones based on their transduction principles. Dynamic types can be further subdivided into moving-coil microphones and ribbon microphones. Common commercial microphone types include condenser microphones, crystal microphones, carbon microphones, and dynamic microphones. Common condenser microphones use two types of energy sources: DC bias power supplies and electret films. Both these condenser microphones and crystal microphones convert acoustic energy into electrical energy, generating a varying electric field. Carbon microphones use a DC voltage source; sound vibrations change their resistance, thereby converting acoustic signals into electrical signals. Condenser, crystal, and carbon microphones all produce a voltage signal proportional to the displacement of the sensitive diaphragm, whereas dynamic microphones produce a voltage signal proportional to the vibration velocity of the sensitive diaphragm. Dynamic microphones use permanent magnets as an energy source and convert acoustic energy into electrical energy based on electromagnetic induction.

KONARIKZAVESOVA electrical component principle

A photodiode is a semiconductor device that converts optical signals into electrical signals. Its core part is also a PN junction. Compared with ordinary diodes, the structural difference is that, to facilitate the reception of incident light, the PN junction area is made as large as possible, the electrode area is made as small as possible, and the junction depth of the PN junction is very shallow, generally less than 11 micrometers. Photodiodes operate under reverse voltage. When there is no illumination, the reverse current is very small, known as dark current. When illuminated, photons carrying energy enter the PN junction and transfer energy to bound electrons in covalent bonds, causing some electrons to break free from the covalent bonds, thereby generating electron-hole pairs, known as photogenerated carriers. Under the action of reverse voltage, they participate in drift motion, significantly increasing the reverse current; the greater the light intensity, the greater the reverse current. This characteristic is called "photoconductivity." The current generated by a photodiode under normal illumination is called photocurrent. If a load is connected in the external circuit, the load receives an electrical signal, and this electrical signal changes correspondingly with changes in light. Photodiodes are photosensitive devices widely used in electronic circuits. Like ordinary diodes, photodiodes have a PN junction. The difference is that the photodiode housing has a transparent window to receive light irradiation, achieving photoelectric conversion. In circuit diagrams, the text symbol is generally VD.

KONARIKZAVESOVA electrical component function

The starter solenoid switch is a key component of the starter, and its design quality directly affects the reliability of the starter. The starter solenoid switch has two functions: first, it connects the main circuit to make the starter rotate; second, it pushes the drive gear out via a 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. Additionally, it is required to minimize volume and weight as much as possible. Based on these characteristics, the contact structure of solenoid switches generally adopts a contact form, i.e., the moving contacts are made into bridge-shaped or disc-shaped forms 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 within a 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-operating initial position. During starting, the starter drive gear needs to move forward by approximately 12-20mm. Therefore, when the solenoid switch begins to close, a large magnetomotive force is needed to generate the necessary initial suction force. After actuation, the air gap decreases, and the electromagnetic suction force increases sharply, far exceeding the force required to maintain the closed state. For this reason, the solenoid switch uses two coils (an attraction coil and a holding coil). Initially, both the attraction coil and the holding coil jointly generate electromagnetic suction force. After the switch contacts close, the attraction coil automatically exits the operating state, and only the holding coil maintains the switch in the closed state. The holding coil current is relatively small and can be wound with thinner wire, which 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.
