摘要
提出一种转子绕组混联的倍极感应励磁新结构，导出了转子励磁电流的解析表达式。理论分析和实验结果证明，采用该结构可显著提高倍极感应励磁同步发电机的磁势感应系数，使倍极感应励磁同步发电机的比功率达到传统励磁方式的水平。
In this paper, a new configuration of double-pole induced excitation with mixed connected rotor winding is proposed, the analytic expression of field current is also derived.Analysis and test results show that the MMF transfer coefficient of the new configuration can be significantly improved, and the power output per unit weight of effective material used will increase to the level of conventional excitation scheme.
