Abstract
Pokretanje asinkronih motora ostvarivo je raznim metodama od kojih svaka ima svoje prednosti i mane te primjenu za određeni tip asinkronog motora. Mnoge metode pokretanja više nisu aktualne te se u današnje vrijeme ponajviše koristi pokretanje uz pomoć preklopke zvijezda -trokut ili korištenjem mekog upuštača za motore vrlo velikih snaga. Nadalje, snaga električne mreže je porasla u odnosu na prošla desetljeća što omogućuje uključenje motora manjih i dijelom srednjih snaga direktnim spajanjem na mrežu što je ujedno najjednostavnija i najraširenija metoda pokretanja asinkronih motora. Sa druge strane, regulaciju brzine vrtnje motora moguće je izvršiti na mnogo načina. Razvojem energetske elektronike i primjenom tranzistora, trenutno najčešća metoda regulacije brzine ostvarena je korištenjem frekvencijskih pretvarača koji istovremenim mijenjanjem amplitude i frekvencije napajanja motora omogućavaju široku upotrebu primjene motora i veliku efikasnost iskorištenja energije.
Abstract (english)
Starting induction motors can be achieved by various methods, each with its own advantages and disadvantages and application for a particular type of induction motor. Many startup methods are no longer up-to-date, and nowadays most of the time startup is done with the help of a star-delta switch or using a soft starter for high power motors. Furthermore, the power of the mains grid has increased over the past decades, which enables the inclusion of small and partially medium power motors by directly connecting to the grid, which is also the simplest and most widespread method of starting asynchronous motors. On the other hand, the motor speed can be controlled in many ways. With the development of power electronics and the use of transistors, currently the most common method of speed control is achieved by using frequency converters that, while changing the amplitude and frequency of the motor power supply, allow wide use of motor applications and its high energy efficiency.
