In this paper, we will deal with the efficiency improvement and power factor of a 2.2㎾, 2-pole, three-Phase Line start permanent magnet synchronous motor (LSPM) using the saliency ratio, that is the ratio of q-axial inductance to d-axial inductance, and the inductance difference between q-axial difference in d-axis inductance (Ld) and q-axis inductance (Lq). The efficiency im ... 전체 초록 보기
