The result shows that the characteristics depend on mainly the commutating reactance-load factor and the direct-axis armature reactance of the exciter, and that the greater these two parameters, the better the current-linear-amplifier characteristics is. 结果表明,在恒速运行时,电流线性放大器特性的好坏主要取决于电机的电抗负载因素,以及直轴同步电抗大小。
