Abstract In this paper, a new type of interior composite-rotor bearingless permanent magnet synchronous motors (BPMSMs) with two layer permanent magnets (PMs) is proposed. In order to reduce the torque ripple of this kind of motors, the sizes of PMs are optimized. Moreover, the magnetic field analysis of the interior composite-rotor BPMSM with two layer PMs is carried out by the finite element method (FEM). The corresponding static electronic magnetic characteristics at no load, including magnetic field, PM flux linkage and inductance, are studied in detail. In addition, electromagnetic torque characteristics and suspension force characteristics are also investigated thoroughly. The results of the analysis and simulation lay a significant foundation for further research on the interior composite-rotor BPMSMs with two layer PMs.

The Magnetic Field

The paper presents the magnetic field distribution from the armature winding currents in the slotted air gap of surface-mounted permanent magnet (SMPM) motors using the Schwarz- Christoffel(SC) mapping. With the method, a slotted structure of SMPM motors is transformed into a geometrically simpler domain. Compared with the result from the finite element method, the accuracy of the method is verified. The presented work can be a basic tool for optimizing design and performance analysis of permanent magnet motors.
