Amorphous alloys have attracted much attention in the field of high-speed motors because of their ex-cellent comprehensive soft magnetic properties,especially their extremely low loss at high frequencies.In this paper,the advantages and types of amorphous motor are summarized,the key preparation processes of amor-phous stator core are reviewed,and the advantages and disadvantages of radially laminated and axially wound core,modular splicing and integral forming core,slotted and slotless core are compared.The effects of the a-bove-mentioned preparation processes on the properties of amorphous strip and iron core are summarized from the perspectives of annealing treatment,dipping curing and processing forming methods.Finally,combining with the latest research progress of amorphous motor,the problems existing in the application of amorphous al-loy to the stator core of amorphous motor are analyzed,and the development of machining methods for amor-phous motor stator core in the future is prospected.
