Novel manufacturing technologies for rotors of high-performance reluctance machines for the resource-efficient mobility of the future

Synchronous reluctance machines (SRM) feature magnet-free rotors and are characterized by high efficiency. However, they have so far not been suitable for use in automotive applications due to limited mechanical strength at high  speed  and the associated lower power density.

 

Aim and approach

The aim of the research project was the systematic analysis of a new rotor design to improve the operating behavior of synchronous reluctance machines. On the one hand, the use of materials with low magnetic conductivity in the area of the rotor webs increased the power and torque density as well as the reluctance ratio by reducing the rotor leakage flux. On the other hand, the operational stability could be significantly increased by a new fiber-reinforced design, enabling operating speeds > 10,000 min-1.
