- Abstract
- This paper proposes a novel hybrid-excited wound-rotor synchronous machine (HE-WRSM) with asymmetrically
positioned permanent magnets (PMs) to make full use of reaction torque and reluctance torque, thus to improve the machine
performance, including torque, efficiency, and power factor. To highlight the advantage of the proposed HE-WRSM, the
conventional WRSM and HE-WRSM are adopted for performance comparison under the same operating conditions. All machine
characteristics are predicted by the finite element method (FEM) using the commercial software, JMAG-Designer. The analysis
results finally demonstrate that the proposed HE-WRSM exhibits highly improved torque, power factor, and efficiency, when
compared to the conventional machines. Furthermore, the proposed HE-WRSM is verified to have superior endurance against
the magnet irreversible demagnetization within two times of the rated current excitation.
