A new application and experimental validation of moulding technology for ferrite magnet assisted synchronous reluctance machine

This paper introduces a new application of moulding technology to the installation of ferrite magnet material into the rotor flux barriers of Ferrite Magnet Assisted Synchronous Reluctance Machine (FASynRM). The feasibility of this application with respect to manufacturing process and motor performance has been demonstrated. In comparison to the conventional ferrite magnet installation approach, moulding technology has obvious advantages of improved mechanical strength of the multi-flux-barrier rotor structure, simplified installation process, reduced processing cost and in the same time, allowing a high degree of flexibility in the rotor flux barrier shape design. A prototype is manufactured using the moulding technology, and the attractive features are verified by detailed experimental results.
