U radu je simuliran elektromotorni pogon manjeg putničkog električnog broda. Pogon se sastoji od izvora napajanja (baterije), frekvencijskog pretvarača i asinkronog motora. Ključne dimenzije motora određene su analitički, nakon čega je motor m

U radu je provedena simulacija pogona električnog broda. Korišten je program Matlab, odnosno paket Simulink. Kao pogonski stroj korišten je asinkroni motor, a kao izvor energije istosmjerni naponski izvor (baterija). Budući da se motor napaja iz

This paper describes modern design of an onboard traction transformer, i.e. design of the active part and cooling system depending on application and use of special materials. The influence of power supply characteristics (AC or DC) on transformer de

The EMU transformer in operation is loaded with current which contains a considerable amount of harmonics. The harmonics in load current raise the eddy loss and stray flux loss and increases the total loss calculated or measured with purely sinusoida

Traction transformers are used for a power supply of EMU (electric multiple unit) or electrical locomotive from the catenary system. They are installed on a vehicle and must be placed in an area defined by the requirements of designers due to custome

Izolacijski materijali više toplinske klase prikazani u ovom referatu su minimalno toplinske klase F (155°C) i ugrađeni su u prototip transformatora za elektromotorni vlak. Zbog više radne temperature transformatora klasični izolacijski materija
