KB Electronics马达控制器KBVF-23特价库存
**手动设置装置参数并优化成功后,可以通过Drive Monitor软件连接PC和直流调速装置,打开软件所有参数将件中显示,然后即可在线进行参数查看、设置、调整。也可将参数下载保存到PC中备份,以后换了新的直流调速装置可直接上传参数,不必再手动一一设置。
VVVF变频、矢量控制变频、直接转矩控制变频都是交—直—交变频中的一种。其共同缺点是输入功率因数低,谐波电流大,直流电路需要大的储能电容,再生能量又不能反馈回电网,即不能进行四象限运行。为此,矩阵式交—交变频应运而生。由于矩阵式交—交变频省去了中间直流环节,从而省去了体积大、价格贵的电解电容。它能实现功率因数为l,输入电流为正弦且能四象限运行,系统的功率密度大。该技术虽尚未成熟,但仍吸引着众多的学者深入研究。其实质不是间接的控制电流、磁链等量,而是把转矩直接作为被控制量来实现的。
PLCDirect was established as a privately held Georgia corporation that is a subsidiary of Koyo Electronics (part of the multi-billion dollar JTEKT group of companies). Koyo had designed and manufactured PLCs for some of the world's largest PLC companies, including General Electric, Texas Instruments, and Siemens. However, the future plans of these companies and Koyo were not compatible
