例句与用法
- Direct torque control ( dtc ) , which developed after the field - oriented control , is a novel and high - performance control strategy for ac variable - frequency drives
摘要直接转矩控制技术是继矢量控制技术之后的一种新型高性能的交流变频调速技术，它以转矩响应快、结构简单明了、鲁棒性好等一系列优点受业界人士的广泛关注。 - Data acquisition card pcl813 gathers the data transmitted by the testing scene ’ s each sensor , and then the data are transmitted to the industrial personal computer ( ipc ) by the data bus pci of ipc , rs232c realizes the serial communication between the ipc and lower position machine plc , plc controls the performance examination system of agricultural products processing machines , rs485 realizes the serial communication between plc and the variable - frequency drive ( vfd ) , vfd changes the alternative variable frequency motor ’ s frequency , thus which control the flow of raw materials
通过数据采集卡pcl813采集现场各个传感器传来的数据,然后通过工控机的pci数据总线把数据传给上位工控机,工控机与下位机plc之间采用rs232c进行串行通信, plc控制农产品加工机械的性能检测系统, plc与变频器之间通过rs485串口通信,变频器通过改变交流变频电动机的频率从而控制交流异步电动机的转速,从而控制原料的流量。
百科释义
A variable-frequency drive (VFD) (also termed adjustable-frequency drive, variable-speed drive, AC drive, micro drive or inverter drive) is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage.
