The Calculation of Two Magnetisation Curves of the Switched Reluctance Motor at Intermediate Rotor Positions

本文提出了开关磁阻电机转子板前沿与励磁极前沿重合位置,转子板前沿与励磁极中心线重合位置两情况下磁化曲线的解析计算法,考虑了磁极的局部饱和及磁分流现象,提出用附加气隙和动态阶梯形磁极的处理方法,并将该方法计算结果与有限元法及实验所得结果进行了比较。

An analytical calculation method for magnetisation curves of a switched reluctance motor is presented, which is suitable for the aligned POsition of the forth edges of rotor poles and stator exciting POles and for the aligned position of the forth edges of rotor poles with the centre line of stator exciting POles. The effects of local saturation and magnetic diversion in the magnetic circuit are concluded. and dealt with by virtue of an added airgap and a dynamic step pole. Results are compered with those from FEM and test data.
