Design of 6-slot 2-pole high-speed permanent magnet synchronous machines with Tooth-Coil windings

This paper investigates the advantages and drawbacks of High-Speed Permanent Magnet Synchronous Machines (HSPMSM) having a special topology. The analysis is made by using 3.5 kW and 11 kW machines prototypes. The machines under consideration have 6 slots and 2 poles. The rotor is manufactured as a full cylindrical magnet inside a retaining sleeve. Non-overlapping Tooth-Coil (TC) windings were implemented to improve the manufacturing process. The similarities and differences of the prototypes are discussed. Machines' performances are verified by test measurements.
