Abstract

U pogonu je još uvijek nemali broj motora starijih i od 20 godina. Njihova učinkovitost i karakteristike ne zadovoljavaju današnje standarde. Prematanje statorskog namota motora je način na koji se mogu stari motori prilagoditi današnjim standardima. Ugradnjom dvoslojnog namota s optimiranim korakom svitka i brojem zavoja svakog svitka mogu se popraviti karakteristike motora, smanjiti gubici i povećati korisnost motora.
Programski alat BobiSoft ubrzava postupak i proračune optimizacije namota statora. Potrebno je unijeti parametre motora i izvornog namota te zahtjeve za novi namot, a BobiSoft iterativnim postupcima određuje koja konfiguracija namota daje najbolje karakteristike motora. Relativno složeni i vremenski zahtjevni projektantski poslovi su olakšani i skraćeni.

Abstract (english)

The number of motors older than 20 is still working. Their efficiency and characteristics do not meet today's standards. Changing the stator winding is the way the old motors can adapt to today's standards. By installing a double-layer winding with an optimized coil pitch and coil turn number, the motor features can be improved, reduced losses and increased motor efficiency.
The BobiSoft program tool accelerates optimization process. Motor and original winding parameters as well as requirements for new winding are required and BobiSoft will use iterative procedures to determine which winding configuration gives the best motor characteristics. Relatively complex and lengthy design work is simplified and shortened.
