What EMRAX does
EMRAX d.o.o. is a Slovenian manufacturing and development company founded in 2005 by Roman Susnik that designs and produces axial flux electric motors and generators. Its core product line consists of five standardized motor platforms — the EMRAX 188 (60 kW), 208 (86 kW), 228 (124 kW), 268 (210 kW), and 348 (340 kW) — supplemented by the EMRAX TWIN stacked configuration that doubles output and by accessories including resolvers, encoders, shafts, and coolant fittings. The motors are sold on the basis of claimed best-in-class power density (up to 10 kW/kg) and efficiency (up to 98%), with three cooling options (air, combined, liquid) and gearless direct-drive capability targeting aerospace, automotive, marine, industrial, and motorsport customers.
The company operates from a single headquarters and manufacturing site in Kamnik, Slovenia, processing orders through an online configurator that generates EUR-denominated Pro-forma Invoices and ships globally via DHL Express (up to 7 business days inside the EU, 14 days worldwide). Pricing follows a unit model with volume discounts for larger quantities, and online orders are capped at 20 units per product type, with custom arrangements for higher volumes. EMRAX supports its hardware with a curated ecosystem of seven motor-controller integration partners and offers technical guidance for powertrain integration, while ISO 9001:2015 and EMC certifications enable entry into regulated automotive and aerospace supply chains.
The business is privately held, founder-owned, and lean (11-50 employees), with no disclosed venture or institutional funding beyond a EUR 100,000 EU NextGenerationEU digital-transformation grant received in 2025. Reference customers include NASA, Pipistrel, Cessna, Alakai, Google, Magna, Solar Flight, Nessmann Boote, and STORM Eindhoven, alongside a long tail of university Formula Student and EV research teams. EMRAX transitioned from small-batch bespoke production to standardized serial manufacturing around 2020 and continues to expand geographically and across verticals under a direct B2B sales-led model.
