电机为交流异步电机，纸机设计最高转速为1800m/min,传动控制系统为TMdrive-10e2，PWM控制的交直交变频矢量控制系统，功率元件采用绝缘栅双极晶体管(IGBT)。
传动逆变器柜类型较多，250KVA以下为抽屉式，250KVA以上为柜式结构，根据电机容量的差异来选用不同容量控制系统，用于纸机的变频控制。
逆变器的传动矢量控制组成：速度给定环节、速度调节器、D/Q轴电流调节器、磁通调节器、电压调节器、PWM控制器等组成。主板在矢量控制系统完成IGBT触发信号后，把触发脉冲传送到逆变器，控制IGBT导通和关断，得到所需电机近似于正弦波的输入电压和频率，进而调节电机转速。
2.4 数据通信
传动系统和PLC间通信采用FL-NET总线,光纤连接，变频器与HUB之间，以太网通讯。结构仍以图2为例。
PLC系统配置了一块FL612接口模块和一块EGD模块，与各变频器进行数据交换。各变频器地址均在EGD中配置，传动与PLC的通信及传动与传动之间的通信都是通过EGD来完成数据交换的。
FL-NET网络以Ethernet为物理层，采用总线拓扑结构，是日本采纳的一种PLC网络标准，其协议栈高层为UDP/IP+ UDP/IP+独自循环通信协议，保证了通信的实时性。
完成PLC系统与传动系统间数据交换基于EGD(Ethernet Global Data)以太网全局数据处理通信，EGD协议是美国GE自动化公司基于以太网技术的数据交换协议，它以数据报文形式在一个发送者和多个发送者之间实现100Mbps数据高速传送，遵循UDP/IP独自循环通信协议。数据发送时间间隔短，安全性强，不易丢失，各站为双向角色，既是服务器也是客户端。
3. 系统控制功能
TMEIC集成控制器完成整个纸机的速度计算与控制、负荷分配计算与控制、电机同步计算与保护等功能。
卫生纸机的速度基准以烘缸Yankee为准，Yankee烘缸由两台电机驱动，1#Yankee电机为master，控制方式为速度控制，2#Yankee电机为slave，控制方式为转矩控制，两台电机为一个整体，要求速度同步。generation of control system will fully meet or exceed that of similar imported brand equipment, and meet the upgrading of equipment, with considerable flexibility and expansion.
In order to achieve the preset R & D objectives, at the beginning of the project, the brand and model selection of PLC, the core controller of the control system, has become one of the key factors affecting the success or failure of the project. After repeated comparison of various series PLCs of the mainstream brand PLC in the system, it is finally determined to select the latest small PLC s7-1200 launched by Siemens as the core controller of the control system of the new generation reflow equipment.
Jintuo's new generation RN (a) d reflow soldering equipment was launched on the market in the spring of 2010 and was immediately supported by our customers. Many superior performances such as the significant improvement of production efficiency, the significant reduction of energy consumption and humanized design have been highly praised by customers. The good performance of the equipment must rely on the high reliability and good
