Design of a novel axial-radial flux permanent magnet motor

Abstract

The paper describes the design and construction of a novel axial-radial flux permanent magnet (PM) machine (ARFPMM). The structure presented in the paper combines dual-rotor axial-flux PM motor and radial-flux PM motor, with both axial and radial PMs and a common electromagnetic core. This core built by soft magnetic composite offers the pass for both radial and axial flux. A new technique called fan-ring shaped windings combines the fan-shape and ring-shape winding described in the paper to shorten the end-winding and customized for the machine. A simplified method is presented in the paper to design and optimize the machine, and have been validated with Finite Element Analysis (FEA). Some details on the design and structure of the machine are presented and a 5 KW ARFPMM is designed to discuss the performance and have been validated with Finite Element analysis (FEA).
