Summary:The results of research on high-speed electric machines with different topologies of a stator core made of amorphous iron have been presented, and the most efficient topology has been selected. To determine the efficiency of each topology, four experimental models have been designed and fabricated and the losses in stator cores have been studied. Based on the experimental results, four computer models have been developed. The obtained data can be used when designing high-speed slotless electric machines with a power of 50–60 kW, concentrated windings, and a rotational speed of 60 000 rpm.
