Performance investigation and comparison of Line Start-up Permanent Magnet Synchronous Motor with super premium efficiency

Abstract

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

Overview of research evolution in the field of line start permanent magnet synchronous motors

“…During 2009–12, Almeda et al [84, 85] in a series of two papers discussed various aspects of the new standards for high efficiency motors, including requirements for the super‐premium efficiency class for electric motors. In 2012, Feng et al [86] discussed the design and performance investigations of LSPMSMs of super‐premium efficiency class. For this class, mere copper and lamination material had to be used and the squirrel cage was made of casting copper.…”
