IC697CMM711

"矢量控制"把电机的电流值进行分配，从而确定产生转矩的电机电流分量和其它电流分量（如励磁分量）的数值。　　　　"矢量控制"可以通过对电机端的电压降的响应，进行优化补偿，在不增加电流的情况下，允许电机产出大的转矩。此功能对改善电机低速时温升也有效。 1、什么是变频器？ 变频器是利用电力半导体器件的通断作用将工频电源变换为另一频率的电能控制装置。 2、PWM和PAM的不同点是什么？ PWM是英文Pulse Width Modulation(脉冲宽度调制)缩写，按规律改变脉冲列的脉冲宽度，以调节输出量和波形的一种调值方式。　 PAM是英文Pulse Amplitude Modulation (脉冲幅度调制) 缩写，是按规律改变脉冲列的脉冲幅度，以调节输出量值和波形的一种调制方式。
