Taunuslicht Optoelektronik 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 or asynchronous (the speed of the stator magnetic field does not remain synchronized with the rotor rotation speed). The motor mainly consists of a stator and a rotor. The direction of force-induced motion of current-carrying conductors in a magnetic field is related to the direction of the current and the magnetic field lines (magnetic field direction). The working principle of an electric motor is the force exerted by the magnetic field on the current, causing the motor to rotate.

Taunuslicht Optoelektronik electrical component principles

Light emission principle of laser diodes: The P-N junction in a laser diode is formed by two doped gallium arsenide layers. It has a parallel-end structure, parallel to one mirror (highly reflective surface) and one partially reflective surface. The wavelength of the emitted light is directly related to the length of the junction. When the P-N junction is forward-biased by an external voltage source, electrons move through the junction and recombine as in ordinary diodes. When electrons recombine with holes, photons are released. These photons strike atoms, causing more photons to be released. As the forward bias current increases, more electrons enter the depletion region, leading to the emission of more photons. Eventually, some photons drifting randomly within the depletion region strike the reflective surfaces perpendicularly and are reflected back along their original paths. The reflected photons are again reflected from the other end of the junction. This movement of photons from one end to the other occurs continuously multiple times. During photon movement, due to the avalanche effect, more atoms release more photons. This process of reflection and generation of increasing numbers of photons produces a very intense laser beam. Each photon generated in the emission process described above is identical to other photons in terms of energy level, phase relationship, and frequency. Therefore, the emission process yields a laser beam of a single wavelength. To produce a laser beam, the current of the laser diode must exceed a certain threshold level. Current below the threshold level forces the diode to behave as an LED, emitting incoherent light.

Taunuslicht Optoelektronik electrical component structure

A bipolar junction transistor is fabricated on a semiconductor substrate with two closely spaced PN junctions. These two PN junctions divide the entire semiconductor into three parts: the base region in the middle, and the emitter and collector regions on the sides. The arrangement types are PNP and NPN. Corresponding electrodes are drawn from the three regions: base b, emitter e, and collector c. The PN junction between the emitter and base regions is called the emitter junction, and the PN junction between the collector and base regions is called the collector junction. The base region is very thin, while the emitter region is thicker with a high impurity concentration. In PNP type transistors, the emitter "emits" holes, whose movement direction is consistent with the current direction, so the emitter arrow points inward; in NPN type transistors, the emitter "emits" free electrons, whose movement direction is opposite to the current direction, so the emitter arrow points outward. The direction of the emitter arrow also indicates the conduction direction of the PN junction under forward voltage. Both silicon and germanium bipolar transistors come in PNP and NPN types. Transistor package forms and pin identification: Common transistor packages fall into two main categories: metal and plastic. Pin arrangements follow certain patterns. When viewed from the bottom with the three pins forming the vertices of an isosceles triangle, the order from left to right is e b c; for small and medium-power plastic transistors, orient the flat side toward you with the three pins facing downward, and the order from left to right is e b c.
