Investigation of axial field permanent magnet motor utilizing amorphous magnetic material

Abstract

Amorphous magnetic material (AMM) offers extremely low iron losses, specifically at higher supply frequencies, which make it a good candidate for high-efficiency, variable-speed motor applications. However, due to handling and cutting limitations, AMM has not been widely utilised in rotating electrical machines. This paper describes an axial field permanent magnet motor, which utilises a cut-AMM stator. The design and construction of the prototype machine is also described in the paper. In addition, the paper explains the methods for parameter measurements and provides calculated performance characteristics that are based on the measured parameters.
