碩士 === 國立成功大學 === 電機工程學系 === 104 === The Bureau of Energy, Ministry of Economic Affairs indicated that industrial electricity reached 55% of the overall electricity consumption, and motors used 70% of industrial electricity. Moreover, it’s about 48.8% of low voltage motors been used in fans and pumps. Most of pumps use single phase induction motors (IM); however, in the trend of pursuing higher efficiency motors and energy standards, single phase IMs with the second side copper loss have lower efficiency compared with other kinds of motors. Hence, a single-phase IM with synchronous reluctance motor’s (SynRM) flux barriers structure is proposed in this study, namely the line start synchronous reluctance motors (LSSynRM), which is capable to overcome speed reduction while load is added. The proposed design isn’t only able to maintain high synchronous speed with high flow for pumps, but also can reduce the second side copper loss. Further, LSSynRM maintains the capability in high efficiency range. A prototype of LSSynRM has been constructed, and the experimental result is compared to FEM simulation to verify the line-start ability and fix-speed ability.
