SciMo – High Power Electric Motors GmbH

SciMo – High Power Electric Motors GmbH is a German manufacturer of high-performance electric drive systems. The company builds electric motors with peak power densities of over 17 kW/kg and continuous power densities above 10 kW/kg, with motor power ranging from 20 kW up to 1000 kW and motor speeds up to 46,000 rpm. Its motors achieve efficiency over 97% and use a copper filling factor above 70%. Alongside its motors, SciMo offers custom inverter solutions with efficiency up to 99%, power up to 500 kW, and current up to 1200 ARMS. The company states that its electric motors have been developed and utilized since 2013. Its technology targets applications that demand the highest levels of power density and efficiency, including high-efficiency motors, specialized motors, and test bench motors. SciMo motors have been proven in various racing series and have consistently demonstrated high quality standards. SciMo also develops high-torque aviation motors with inverters integrated into the motor housing, offering high torque at low rotor speed, air- or water-cooled variants, and a superior power-to-weight ratio optimized for aviation requirements. The company has delivered inverter-integrated direct drives for electric flight applications and has supplied generators used in electric short take-off and landing (eSTOL) aircraft flights. SciMo's product line includes the SY45 series for test bench applications up to 30,000 rpm, the SY43.B generator used in electric flight, and the SY61.C electric motorsport motor. The company is based in Germany and operates as a private corporate brand under the name SciMo – High Power Electric Motors GmbH.
