Abstract

The line-start permanent magnet synchronous motor without starter devices has a wide range of industrial applications, thus this paper presents a kind of line-start surface-mounted and interior permanent magnet synchronous motor (LSSIPMSM), which has a canned conducting layer which made of the copper between the surface-mounted PMs and rotor core. The LSSIPMSM performances were analyzed and the key parameters were optimized based on combinations of analytical method and finite element method. The dynamic, steady state performances of LSSIPMSM with PMs of different heights and canned conducting layers of different thicknesses were investigated. Finally, the optimal parameters were obtained. Electromagnetic finite element model of the LSSIPMSM was established to analyze the starting capability and steady state synchronization, and the temperature field of LSSIPMSM with different demagnetization conditions was researched by 3-dimensional temperature finite element model. The results show that LSSIPMSM has good dynamic and steady state performances.
