This paper present the design of a permanent-magnet starter-generator unit for aerospace applications from concept to implementation. Attention is placed on the required failure-rates, system architecture, power density, prototype implementation and experimental test-setup. Measu

In general, PM machines with conventional integer slot distributed winding (ISDW) schemes exhibit significant cogging torque resulting in high torque ripple which makes them unsuitable for EV applications which require low torque pulsations. This paper presents detailed analysis
...
Electrical machines for safety critical applications need to be able to withstand all possible short-circuits, including those between individual turns. In high-speed machines multiple parallel strands may be used to reduce AC losses in the winding, increasing the likelihood of a
...
The use of concentrated windings in electrical machines leads to significant rotor losses due to severe space harmonics in the airgap. Metallic retaining sleeves and sintered magnets used in high speed rotor construction have low electrical resistivities, leading to larger associ

Fractional pitch, concentrated winding machines are recently enjoying attention due to their suitability as basis for fault tolerant machine designs. The concentrated nature of the armature current distribution yields significant rotor eddy current loss production due to the harm
