Abstract

Direct driving system is a dominant development direction in the modern electromechanical system, and the permanent magnet disc synchronous motor (PMDSM) is considered as an attractive alternative for its high efficiency and torque density. In this paper, a novel PMDSM characterized by flux concentrating with fractional slot and concentrated winding is presented firstly, then the process of design and analysis of the motor is introduced to gain the optimal structure dimension for minimum cost price. Compared with the surface-mount PMDSM, the motor has better output performance.
