ReMos2 - effective reluctance machine for emission-free mobility without rare earth 2

In the previous project ReMos, a new machine concept for increasing the efficiency of synchronous reluctance machines (SynRM) or hybrid synchronous reluctance machines was presented. The new concept is based on solving the conflict of objectives between optimal electromagnetic utilization of the rotor and mechanical load capacity that exists in pure SynRMs by introducing an FRP reinforcement into the rotor and using magnets without rare earths. In this way, the efficiency can be improved and the power density increased through greater final speeds of the machine. For the second phase - ReMos2 - the construction of the prototypes is planned. For this purpose, the assumptions made about the interfacial strength between the electrical steel strip and the fiber-reinforced polymer will be investigated experimentally, the rotor geometry will be adapted according to the results, tools for injecting the polymer into the flux barriers will be designed and the existing rotor and stator concepts will be validated through setups and measurements.

Research content:
  • Metrological validation on assembled prototypes of the machine
  • Adhesion & peel tests at the electrical sheet - polymer interface to determine the maximum permissible contact forces
  • Design & construction of the injection mold for the production of the rotors
  • Develop strategies for optimized overall efficiency in the drive cycle & investigate the effect of skewing on magnetic reversal
  • Application to the fully designed engine & validation on the test bench
