Abstract

New brushless and exciterless, single-phase and three-phase synchronous generators are presented, and the analysis of the characteristics and the test results are reported. In the three-phase generator, the stator armature winding is connected electrically with the secondary winding of a transformer. In the single-phase generator, the stator is provided with the armature winding and the exciting power-supplied winding, and the armature winding is electrically connected with the excitation power-supplied winding through a capacitor. In these generators, AC excitation current flows in the armature winding simultaneously with the load current. The ratio between the number of poles made by the load current and that by the AC excitation current is 2 or 1/2. Thus, the generator can be made brushless and exciterless. The rotor of the single-phase generator is provided with a balanced two-phase field winding. The rotor of the three-phase generator is provided with a bridge-type field winding. Circuit configurations for such brushless and exciterless synchronous generators are presented. Steady-state performances of the three-phase generators are analyzed. Experiments for these generators performed on a 2.0 kW unit are reported.<>

无刷无励磁自激同步发电机的特性

介绍了新型无刷无励磁、单相和三相同步发电机，并对其特性进行了分析和试验。在三相发电机中，定子电枢绕组与变压器的二次绕组电连接。在单相发电机中，定子上设有电枢绕组和励磁供电绕组，电枢绕组通过电容器与励磁供电绕组电连接。在这些发电机中，交流励磁电流与负载电流同时在电枢绕组中流动。负载电流与交流励磁电流产生的极数之比为2或1/2。因此，可以使发电机无刷和无励磁。所述单相发电机的转子上设有平衡的两相磁场绕组。所述三相发电机转子上设有桥式励磁绕组。介绍了这种无刷无励磁同步发电机的电路结构。分析了三相发电机的稳态性能。本文报道了这些发电机在一台2.0 kW机组上的试验结果。
