Abstract—(1)In this article, animproved conformal mapping (ICM) method based on a complex potential functionis proposed. (2) It canimprove the calculation speed and accuracy of magnetic fields forsurface-mounted permanent magnet synchronous motors (SPMSMs). (3) The eccentric-shaped poles arereplaced by equivalent currents, and the improved conformal mapping method isadopted to transform an actual slotted motor air gap to an equivalent rectangularregular slotless air gap. (4) The ICM method improves the speed ofcalculation because its number of mapping times is less than the traditionalconformal mapping (TCM) method. (5) By solving the complex potential generated by the equivalent current inthe rectangular regular air-gap region, the air-gap magnetic field of the SPMSMunder no-load, armature reaction and loaded conditions can be solved. (6)Then, the no-load back-EMF andloaded torque performance under different load conditions are calculated. Theaccuracy of the ICM method is verified by finite-element simulation. (7)In addition, the fastspeed and high accuracy of the proposed ICM method incorporating the complexpotential function for solving the air gap magnetic field has been demonstratedin comparison to the TCM method with the Hague equation. (8) An eccentric-shaped-pole permanentmagnet motor prototype is also built and tested in experiment and the resultsagree with those calculated by the proposed ICM method.

本人看法：该摘要用简短的语言向读者们展示了文章的研究内容，这非常好，不愧是Trans论文的摘要。但从个人的角度看来，也存在一些有待改进的地方。首先，第（4）句前后没有联系，在文本中可有可无。直接去除也毫不影响第（3）句和第（5）句的连贯性。其次，第（2）句和第（7）存在明显的因果关系，却没放在一起，连贯性有待加强，且两句内容也存在部分重复。然后，第（6）句和第（8）句均为验证内容，可放在一起，并增删部分内容。

该摘要的结构可总结为以下结构：
