Emrax 2 Explained

The Emrax 2 is a Slovenian electric motor for powering electric aircraft and other applications, designed and produced by Emrax d.o.o of Kamnik. The company was formerly called Enstroj and based in Radomlje.[1]

By May 2018 the engine was no longer advertised on the company website and seems to be out of production.[2]

Design and development

The Emrax 2 is a brushless 200 Volt design, producing 30to, with an outrunner coil. It has a 94% efficiency. The low working rpm of the engine means that it can turn a propeller at efficient speeds without the need for a reduction drive.[1]

  • Air-cooled version, producing 300NaN0 at 3000 rpm.[1]
    Emrax 2 LC
  • Liquid-cooled version, producing 350NaN0 at 3000 rpm.[1]
