双边定子盘式永磁发电机初步设计及其性能分析

Priliminary Design and Performance Analysis of a Double-sided-stator Disc-type Permanent Magnet Generator

本文对一种双边为开槽定子的永磁盘式发电机的性能进行了分析.由于电机是轴向磁场,采用三维标量位有限元法计算电机的磁场.在磁场计算的基础上,用最小二乘曲线拟合等数值方法,求得电机的电势、电流等.

A generator consisting of a disc-type, double-sided, slotted stator with a sandwiched rotor carrying the Nd-Fe-B permanent magnets is reported in this paper. The three-dimensional method using scalar potential is applied to compute the magnetic field. The machine performance is analyzed on the basis of the field calculation.
