The need to constrain global warming demands new sustainable and green technologies. Line start synchronous reluctance machine technologies offer a big potential for future energy savings in industrial applications. Within this thesis the efficiency and starting capability of a novel line start synchronous reluctance machine in comparison to a common induction machine is analysed. For this purpose a simulation model and a test bench setup were used. With this new motor design a measured efficiency enhancement at rated load from 89.3% up to 92.0% was achieved, corresponding to a loss reduction of about 27.6%. For the chosen 4 kW four pole motor the efficiency rating was improved from IE3 to IE4. Nevertheless a drawback is the low synchronization capability, which limits the range of possible industry applications.
