Overview of Axial Flux Permanent Magnet Generator for Small-Scale Industry

Abstract

A magnetic generator is not like a conventional generator that is produced by the coil. Consequently, this generator used the permanent magnetic field to produce magnetic flux energy. Although, most of the permanent magnet designs produce less aggressive copper winding. This paper provides an overview of axial flux permanent magnet generators for small-scale industries. First of all, the classification and a detailed overview of permanent magnet generators are presented first. The main characteristics of the generators together with their benefits and drawbacks are highlighted. Additionally, an overview of the most recent machine developments is also presented. The design of convenient permanent magnet generators that have been used to create small-scale generator varieties is then reviewed to conclude the most suitable design among axial flux which is the sandwiched construction.
