Project SUTOR Superconducting Speed-Controlled Torque Motor for 25.000Nm

Abstract

SUTOR is a project that is supported by the german ministry of economy and technology (FKZ 0327866A). The partners working on this project are Oswald Elektromotoren and Hochschule Aschaffenburg. Oswald is responsible for the layout of the Motor and its cryostat. Together with the Hochschule Aschaffenburg, Oswald has build a number of coils to determine the loss rates of superconductors when used with AC current and in external, oscillating magnetic fields. These results are taken to proof the at Oswald developed calculations for superconducting motors. The Hochschule Aschaffenburg is measuring the loss rates in superconducting coils and builds an inverter to fit the special requests a motor has when running with superconducting wires. The aim of this project is to realize a high torque motor that has compared to conventional torque motors a lower volume and weight, a higher efficiency and an increased dynamic acceleration.
