Emrax

Emrax d.o.o is a Slovenian electric aircraft engine manufacturer founded by Roman Sušnik and based in Kamnik. The company specializes in the design and manufacture of electric motors for light aircraft, marine and automotive applications. It was founded in 2008 as Enstroj to produce the Emrax line of engines, and the company name was later changed to Emrax. Initially located in Radomlje, the company was relocated to Kamnik. It is organized as a družba z omejeno odgovornostjo, a Slovenian private Limited Liability Company.

In 2005, company founder and engineer Roman Sušnik conducted the first electric-powered aircraft flight in Slovenia and only the third such flight worldwide. During the test, the commercial electric motor used in the aircraft failed due to inherent design limitations. This experience motivated Sušnik to begin developing his own high-efficiency axial flux electric motors. In 2008, he introduced the first generation of motors under the name EMRAX — an acronym for Electric Motor Roman Axial flux. The same year, he established the company under the name Enstroj, focusing on lightweight, compact and highly efficient propulsion systems, particularly for electric aircraft where mass is critical. The early prototypes quickly attracted international attention due to their exceptional power density and efficiency. In 2014, Enstroj rebranded to EMRAX, marking the expansion of its product line and the company's shift toward a global market presence. Between 2014 and 2018, EMRAX carried out intensive development of new motor series (including the 188, 208, 228, 268 and 348). From 2018 to 2020, the company transitioned to stable serial production. Today, EMRAX maintains in-house development and manufacturing in Slovenia, with most of its products exported to international markets.
