| 摘 要： | 永磁交流发电机作为照明电源,被广泛应用于链式和小型拖拉机。所谓外特性是指在额定工作转速下,发电机的端电压 U 与负载电流 I 间的关系,即 U=f(I)。由于永磁交流发电机是属于电流调正系统,因此,只有当由发电机供电的照明负荷一定时,才能获得最佳的功率输出和运行状态。本文用数学分析引出最佳功率输出时的负载值。

| Abstract: | The permanent-magnet alternator served as the lighting sources is widely used in the tracklaying and small-sized tractors.The so-called external features refer to the relationship between the terminal voltage(U)and the load current(I)of the alternator under the operating rated speed ,i.e U=F(i).Since the permanent-magnet alternator belongs to the current adjusting system,only when the lighting load provided by the alternator comes to a certain amount, can the best power output and operating conditions be obtained.This paper analyses the negative load value when the best power output is applied mathematically. |
