SAŽETAK:

Cilindrični linearni motori sa stalnim magnetima su zbog svojih istaknutih osobina sve više zastupljeni u oblastima gde se tradicionalno koriste hidraulični i pneumatski aktuatori. U ovom radu je predložen metod koji se bazira na programiranoj promeni faznog stava struje u cilju ostvarenja veće specifične sile. Predloženi metod uzima u obzir uticaj zasićenja na elektromagnetsku interakciju i oblik struja. Simulacioni rezultati su dobijeni korišćenjem metode konačnih elemenata. Ovakav način određivanja faznog stava se može primeniti na sve mašine sa stalnim magnetima kod kojih je izraženo zasićenje magnetskog kola.

KLJUČNE REČI:

Cilindrični linearni motori sa stalnim magnetima, specifična sila, metod konačnih elemenata, zasićenje magnetskog kola
