Development of a High-Speed Permanent Magnet Machine Using Amorphous Alloy Cores

This paper details the design of high-speed permanent magnet machine made of amorphous alloy core. The motor is rated as 15kW, and base speed is 20000rpm. A multidisciplinary approach is used to optimize the machine. The select of pole-slot numbers is presented in this paper. The effect of converter switching frequency on the machine is analyzed. Meanwhile, the mechanical properties of rotor is analyzed. The machine is prototyped and tested to validate the analytical-computational performances predicted in the design and analysis stage.
