Končni vodnik po električnih motorjih: vse, kar morate vedeti

Uvod

Elektromotor je stroj, ki pretvarja električno energijo v mehansko. Je vlečni konj sodobne tehnologije, ki ga najdemo v vsem, od električnih avtomobilov do pralnih strojev. Elektromotorji se uporabljajo za napajanje najrazličnejših naprav, vključno z ventilatorji, črpalkami, tekočimi trakovi in ​​dvigali.

Kaj je električni motor?

Električni motor deluje z uporabo magnetne sile med dvema ali več tuljavami žice. Ko električni tok teče skozi tuljavo žice, ustvari magnetno polje. Če v bližini prve tuljave postavite drugo tuljavo žice, bo magnetno polje prve tuljave induciralo tok v drugi tuljavi. Ta tok bo ustvaril lastno magnetno polje, obe magnetni polji pa bosta delovali med seboj. Ta interakcija bo povzročila vrtenje druge tuljave.

Količina navora, ki ga proizvaja električni motor, je odvisna od jakosti magnetnih polj in razdalje med tuljavami. Hitrost motorja je odvisna od količine toka, ki teče skozi tuljave.

Zgodovina elektromotorjev

Prvi električni motor je leta 1831 izumil Michael Faraday. Faradayev motor je bila preprosta naprava, ki je uporabljala trajni magnet za ustvarjanje magnetnega polja. Ko je električni tok tekel skozi tuljavo žice, je ustvaril magnetno polje, ki je delovalo s trajnim magnetom. Ta interakcija je povzročila vrtenje tuljave žice.

V naslednjih nekaj desetletjih so številni drugi izumitelji izboljšali Faradayev dizajn. Leta 1873 je Thomas Edison izumil prvi komercialno uspešen električni motor. Edisonov motor je bil uporabljen za napajanje električnih luči.

V začetku 20. stoletja so se električni motorji začeli uporabljati v različnih drugih aplikacijah, vključno z avtomobili, napravami in stroji. Danes so elektromotorji bistveni del sodobnega življenja.

Vrste elektromotorjev

Obstaja veliko različnih vrst elektromotorjev. Nekatere najpogostejše vrste vključujejo:

• Sinhroni motorji: Sinhroni motorji se vrtijo s konstantno hitrostjo, ki je določena s frekvenco električnega toka, ki jih napaja.
• Asinhroni motorji: Asinhroni motorji se vrtijo s hitrostjo, ki je nekoliko manjša od hitrosti električnega toka, ki jih poganja.
• Univerzalni motorji: Univerzalni motorji se lahko napajajo z izmeničnim ali enosmernim tokom. Pogosto se uporabljajo v majhnih napravah, kot so vrtalniki in sesalniki.
• Brezkrtačni enosmerni motorji: Brezkrtačni enosmerni motorji se napajajo z enosmernim tokom. Nimajo ščetk, ki so deli, ki se pri brušenih enosmernih motorjih obrabijo.
• Koračni motorji: Koračni motorji se vrtijo v diskretnih korakih. Pogosto se uporabljajo v aplikacijah, kjer je potrebno natančno pozicioniranje, na primer v 3D tiskalnikih in CNC strojih.

Vsaka vrsta elektromotorja ima svoje prednosti in slabosti. Tip motorja, ki je najboljši za določeno aplikacijo, je odvisen od številnih dejavnikov, vključno z zahtevano hitrostjo, navorom in močjo.

Kako delujejo električni motorji

Elektromotor je stroj, ki pretvarja električno energijo v mehansko. To naredi z uporabo magnetne sile med dvema ali več tuljavami žice.

Ko električni tok teče skozi tuljavo žice, ustvari magnetno polje. Če v bližini prve tuljave postavite drugo tuljavo žice, bo magnetno polje prve tuljave induciralo tok v drugi tuljavi.

Ta tok bo ustvaril lastno magnetno polje, obe magnetni polji pa bosta delovali med seboj. Ta interakcija bo povzročila vrtenje druge tuljave.

Količina navora, ki ga proizvaja električni motor, je odvisna od jakosti magnetnih polj in razdalje med tuljavami.

The speed of the motor depends on the amount of current flowing through the coils.

Basic principles of electric motor operation

The basic principles of electric motor operation are as follows:

1. An electric current flows through a coil of wire, creating a magnetic field.
2. A second coil of wire is placed near the first coil.
3. The magnetic field of the first coil induces a current in the second coil.
4. The current in the second coil creates a magnetic field of its own.
5. The two magnetic fields interact with each other, causing the second coil to rotate.

Different types of electric motor construction

There are many different types of electric motors, but they all work on the same basic principles. Some of the most common types of electric motors include:

• Sinhroni motorji: Synchronous motors have a rotating magnetic field that is synchronized with the electric current that powers them. This type of motor is often used in applications where a constant speed is required, such as in electric clocks and electric generators.
• Asynchronous motors: Asynchronous motors have a rotating magnetic field that is not synchronized with the electric current that powers them. This type of motor is often used in applications where a variable speed is required, such as in electric fans and electric drills.

• Univerzalni motorji: Universal motors can be powered by either AC or DC current. This type of motor is often used in small appliances, such as drills and vacuum cleaners.
• Brezkrtačni enosmerni motorji: Brushless DC motors are powered by DC current. They do not have brushes, which are the parts that wear out in brushed DC motors. This type of motor is often used in applications where high efficiency and long life are required, such as in electric vehicles and electric power tools.
• Koračni motorji: Stepper motors rotate in discrete steps. This type of motor is often used in applications where precise positioning is required, such as in 3D printers and CNC machines.

How electric motors are controlled

The speed and direction of an electric motor can be controlled by changing the amount of current that flows through the coils. The speed of the motor can also be controlled by changing the frequency of the electric current that powers it.

The direction of an electric motor can be controlled by reversing the current that flows through one of the coils. This will cause the magnetic field of the coil to reverse, which will cause the motor to rotate in the opposite direction.

Electric motors are an essential part of modern life. They are used in a wide variety of applications, including cars, appliances, and machinery. Electric motors are becoming increasingly efficient and powerful, and they are playing an important role in the development of sustainable energy technologies.
