IC693DNM200电动机使用工频电源驱动时,电压下降则电流增加;对于变频器驱动,如果频率下降时电压也下降,那么电流是否增加?
频率下降(低速)时,如果输出相同的功率(恒功率)则电流增加,但在转矩(恒转矩)的条件下,电流几乎不变。
采用变频器运转时,电机的起动电流、起动转矩怎样?
采用变频器运转,随着电机的加速相应提高频率和电压,起动电流被限制在150%额定电流以下(根据机种不同,为125%~200%)。用工频电源直接起动时,起动电流为额定电流6~7倍,因此,将产生机械电气上的冲击。采用变频器传动可以平滑地起动(起动时间变长)。起动电流为额定电流的1.2~1.5倍,起动转矩为70%~120%额定转矩;对于带有转矩自动增强功能的变频器,起动转矩为100%以上,可以带全负载起动。
