本文叙述的是一种不需要采用补偿绕组而能自启动的单相绕组感应电动机,启动力矩是由定子上若干种不对称因素的联合作用而产生。其中包括一种在三极下沿着转子旋转方向逐渐缩小的锥形气隙;与主极正交轴线上的各附加极,它们没有线圈而用一种实芯铁磁的分路桥(flux bridges)同各主极的导出边(lagging sides)相连;同时定子磁轭的截面在主极导入端要比导出端大。这些不对称性的作用可提供等值电路作定性的分析。
This paper describes a single-phase winding induction motor that can be self-started without the use of a compensation winding. The starting torque is generated by the combined action of several asymmetric factors on the stator. These include a tapered air gap that tapers along the direction of rotation of the rotor under the triode; the additional poles on the orthogonal axis to the main pole, which have no coils but a solid ferromagnetic bridge (flux bridges) ) Is connected to the lagging sides of the main poles, and at the same time the cross section of the stator yoke is larger at the leading end of the main pole than at the lead-out side. The role of these asymmetries provides a qualitative analysis of the equivalent circuit.
