About 4motec
4motec is a technology startup from Graz in the fields of electronics and e-mobility. The company develops electric inverters for mobility on wheels or with wings as well as extremely small, highly efficient E-motor controllers featuring an integrated, novel cooling concept. By combining a novel air-cooling concept with extremely small power components, the company states that volumetric power density is increased tenfold and power electronics are reduced to 10% of their usual size. The portfolio also includes DC/DC voltage converters, rotary position sensors and patented heat sink solutions for electronics applications such as inverters, chargers, batteries and processors, complemented by metal 3D printing expertise. Another business area is IoT solutions for water damage restoration and moisture control in construction and building renovation. The company is based in Graz and registered in the commercial register under FN 531166 b.
