Abstract This paper presents a new flux-concentrating field-modulated permanent-magnet (FCFMPM) machine. This machine adopts a spoke-magnet outer rotor,which can increase air gap flux density due to the flux-concentrating effect. The stator employs an open-slot rather than split-slot structure to improve space utilization. Based on the “magnetic gearing effect”,the magnetic field produced by the low-speed outer rotor can be modulated by the stator teeth,such that a high-speed magnetic harmonic can be generated in the airgap,which can be used to improve the no-load EMF and torque density of the machine. By using the finite element method(FEM),the static characteristics of the proposed machine including the no-load PM flux linkage,no-load EMF,inductance,cogging torque and electromagnetic torque are analyzed. Moreover,a 5kW prototype is built for experimentation,and the comparison with a commercial PM direct-drive wind power generator is also conducted. The results show that the proposed machine possesses the merits of high torque density,low cogging torque,and robust output characteristics. Also,it confirms that the FCFMPM machine is very suitable for the low-speed direct-drive application,such as wind power conversion.
