Analysis of Factors Designing Permanent Magnet Synchronous Motor

This paper makes analysis about the influence of the PMSM´s performance by some key parameters, such as pole-slot match, length-diameter ratio, magnet thickness and air gap length. For each parameter, we choose the different designing scheme about the PMSM. We calculate the performance of each scheme by FEM, and select motor parameters by comparison. At the last, this paper summarizes that how these parameters influence motor´s performance, and give the method to select them.
