Abstract :
This paper deal about high-speed electrical spindles motor design problems. Electrical as well as mechanical critical aspects are taken into account, highlighting the main drawbacks and physical limits that the designer has to consider. The correlation between the volume minimization and the speed increase is discussed on the basis of the torque density trend of some commercial high-frequency roto-statoric units.
