A Novel Radial- and Axial-Flux Permanent Magnet Synchronous Motor

Abstract

　This paper proposes and fabricates a novel hybrid-flux permanent magnet motor with both axial- and radial-flux. The performance of the proposed motor is measured under the vector control, and is compared with that of only radial-flux part. The efficiency of the hybrid-flux motor is about 71.1 % at 100 min^-1 and about 80.1 % at 200 min^-1 in the region where the output power is large. The efficiency is about 8.2 % higher at 100 min^-1 and 3.6 % higher at 200 min^-1 than those of only radial-flux part.
