This paper presents the performance investigation and design technology of Line Start-up Permanent Magnet Synchronous Motor(LSPMSM) with super premium efficiency, including design consideration and evaluation for motor starting-up, key performance, advanced finite element analysis(FEA) for the design, improvement and verification, prototype build and test, design and test data comparison to Premium® Efficient Induction Motor (PEIM). To assess the design technology, LSPMSM prototype was built amended from a PEIM with the same frame, stator punching and rated output. Based on the prototype test, two novel improvement designs and analyses have been done to eliminate the noise and vibration. Additionally, the comparisons with PEIM on power factor, efficiency, frame size and active material consumption indicated the significant performance improvement and active material cost down can be achieved by LSPMSM.
