Abstract: Amorphous alloy (AA) is attracting more and more attention in electrical machines due to its excellent low loss characteristics. This paper overviews advances on AA electrical machines over the last 30 years, with particular reference to new and novel topologies and processing techniques of AA electrical machines and their key technologies. These include current states and trends for radial-flux AA electrical machines, axial-flux AA electrical machines, influences of processing techniques on electrical performance of AA iron cores, the characteristics of loss and vibration and noise of AA core and AA machines, optimum design of AA electrical machines, etc. The paper highlights the application prospects of the AA electrical machines.

Key words: Amorphous alloy, electrical machine, radial flux, axial flux, axial flux, topologies and processing techniques, loss, noise and vibration.
