《南京市现货1756-OW16I 1756-OW16I》1756-OW16I1756-OW16I1756-OW16IVVVF变频,矢量操控变频,直接转矩操控变频都是交-直-交变频中的一种。其一起缺陷是输入功率因数低,谐波电流大,直流电路需求大的储能电容,再生能量又不能反应回电网,即不能进行四象限运转。为此,矩阵式交-交变频应运而生。因为矩阵式交-交变频省去了中心直流环节,然后省去了体积大,价格贵的电解电容。它能完成功率因数为l,输入电流为正弦且能四象限运转,体系的功率密度大。该技能现在虽没有老练,但仍吸引着很多的学者深入研究。其实质不是直接的操控电流,磁链等量,而是把转矩直接作为被操控量来完成的。具体方法是:——操控定子磁链引进定子磁链观测器,完成无速度传感器方法;——自动识别(ID)依托精确的电机数学模型,对电机参数自动识别;——算出实践值对应定子阻抗,互感,磁饱满要素,惯量等算出实践的转矩,定子磁链,转子速度进行实时操控;——完成BandBand操控按磁链和转矩的Band-Band操控发生PWM信号,对逆变器开关状况进行操控。矩阵式交-交变频具有快速的转矩呼应(<2ms),很高的速度精度(±2%,无PG反应),高转矩精度(<+3%);一起还具有较高的起动转矩及高转矩精度,尤其在低速时(包含0速度时),可输出150%~200%转矩。々一个好产品〃一个好质量〃一个好价格々 々赢得您一份信赖々 〃咱们许诺三大确保:优质确保;原装确保;价格确保 〃咱们许诺三高一低:高品质;高标准;高诺言;贱价格 〃咱们做足三个百分百:百分百原装;百分百优质;百分百贱价 〃咱们给与三个:优质;原装;贱价 质保期内产品有任何问题,咱们将无条件为您退换无忧虑,无顾忌 DCS集散式操控体系,PLC可编程操控器,数控体系,(CPU处理器,模块,卡件,操控器,伺服驱动,驱动器,马达电机,内存卡,电源,机器人备件等)各类工控备品备件产品。(A-B,ABB,GE,FOXBORO,KUKA,SIEMENS,WESTINGHOUSE,SCHNEIDER……) 【质量牢靠】【质优价廉】【价惊四座】【拆包防伪】【当天付款】【顺丰速运】【送货上门】【库存多多】 【厦门光沃自动化设备有限公司】【联系人:陈小姐】【免费热线:***】【24小时开机:*** 】 【作业QQ: 2479261344】 Siemens / ITE HF366 - New Style, New in Box!Siemens / ITE HF366NR - New Style, New in Box!Siemens / ITE HF367 - New Style, New in Box!Siemens / ITE HFD63F250 - New Style, New in Box!Siemens / ITE HFXD63B225 - New Style, New in Box!Siemens / ITE HHFD63F250 - New Style, New in Box!Siemens / ITE HHJD63B400 - New Style, New in Box!Siemens / ITE HHJD63F400 - New Style, New in Box!Siemens / ITE HHLD63B300 - New Style, New in Box!Siemens / ITE HHLD63B400 - New Style, New in Box!Siemens / ITE HHLD63B600 - New Style, New in Box!Siemens / ITE HHLD63F600 - New Style, New in Box!Siemens / ITE HJD63F400 - New Style, New in Box!Siemens / ITE HJXD63B200L - New Style, New in Box!Siemens / ITE HJXD63B225L - New Style, New in Box!Siemens / ITE HJXD63B250L - New Style, New in Box!Siemens / ITE HJXD63B300L - New Style, New in Box!Siemens / ITE HJXD63B350L - New Style, New in Box!Siemens / ITE HJXD63B400L - New Style, New in Box!Siemens / ITE HLD63F600 - New Style, New in Box!Siemens / ITE HLMD63B800 - New Style, New in Box!Siemens / ITE HLMD63F800 - New Style, New in Box!Siemens / ITE HLXD63B500 - New Style, New in Box!Siemens / ITE HLXD63B600 - New Style, New in Box!Siemens / ITE HMD63B800 - New Style, New in Box!Siemens / ITE HMD63F800 - New Style, New in Box!Siemens / ITE HMXD63B800 - New Style, New in Box!Siemens / ITE HND63B100 - New Style, NewSiemens / ITE HND63F120 - New Style, New in Box!Siemens / ITE HNF365R - New Style, New in Box!Siemens / ITE HNF366 - New Style, New in Box!Siemens / ITE HNF366R - New Style, New in Box!Siemens / ITE JXD63B200L - New Style, New in Box!Siemens / ITE JXD63B225L - New Style, New in Box!Siemens / ITE JXD63B250L - New Style, New in Box!Siemens / ITE JXD63B350L - New Style, New in Box!Siemens / ITE JXD63B400L - New Style, New in Box!Siemens / ITE JXD63L400L - New Style, New in Box!Siemens / ITE JXD63S400A - New Style, New in Box!Siemens / ITE LD63F600 - New Style, New in Box!Siemens / ITE LMD63B600 - New Style, New in Box!
