CONVEX线性伺服驱动器
线性放大器顾名思义输入信号和输出信号成线性关系,线性伺服驱动器(放大器)适用于要求特殊的领域,相比普通PWM开关型伺服驱动器,其特点是:驱动平滑,无力矩纹波,无电磁开关噪音,高带宽,并可驱动超小电感量的电机。
线性伺服驱动器,它特别适用于要求低噪音,安静,对EMI/RFI电磁辐射敏感和超平滑运动的应用。线性直流伺服驱动器可以大大减小电机发热,延长有刷电机的电刷寿命。
驱动器可通过按键、跳线对系统进行基本的设置,也可以通过RS232修改系统参数,用户可方便的设定电流极限、动态增益、伺服补偿、偏置量等。使用十分方便。
工作模式:单相电流模式(有刷电机或音圈电机) 接受单端+/-10V模拟输入电流命令,不需反馈信号。驱动器仅有电流环。2相电流模式(3相无刷电机)接受两路+/-10V模拟输入电流命令,驱动器内部生成第三相电流命令。因电流命令包含了换相信号,不需要反馈信号。驱动器仅有电流环。
主要特点:
电噪声低
高带宽
动态SOA保护
无失真过零
性能优势:
超净线性输出有效抑制辐射噪声
基于DSP的设计保证性能,可靠性及方便调试
扩展内部保护监测功能提供了可靠的特性
自动均衡特性自动平衡驱动器及负载
所有设定功能数字化,不需分压计来作调整
采用高速串口实现可编程设置
固态存储器保持所有参数
应用领域:
半导体加工设备
国防工业
工业自动化
LCD平板制造
医药及生物医学研究
PCB电路板制造业
超声检测与测量
步进电机驱动器是一种将电脉冲转化为角位移的执行机构。当步进驱动器接收到一个脉冲信号,它就驱动步进电机按设定的方向转动一个固定的角度(称为“步距角”),它的旋转是以固定的角度一步一步运行的。可以通过控制脉冲个数来控制角位移量,从而达到准确定位的目的;可以通过控制脉冲频率来控制电机转动的速度和加速度,从而达到调速和定位的目的。广泛应用于雕刻机、水晶研磨机、中型数控机床、脑电绣花机、包装机械、喷泉、点胶机、切料送料系统等分辨率较高的大、中型数控设备上。
步进电机的相数是指电机内部的线圈组数,常用的有二相、三相、四相、五相步进电机。电机相数
不同,其步距角也不同,一般二相电机的步距角为1.8度、三相为1.2度、五相的为0.72度。在没有细分驱动器时,用户主要靠选择不同相数的步进电机来满足步距角的要求。如果使用细分驱动器,则相数将变得没有意义,用户只需在驱动器上改变细分数,就可以改变步距角。
解决步进驱动器噪音大如下:
A、如步进电机正好工作在共振区,可通过改变减速比提高步进电机运行速度.
B、采用带有细分功能的驱动器,这是Zui常用的,Zui简便的方法.因为细分型驱动器电机的相电流变化较半步型平缓.
C、换成步距角更小的步进电机,如三相或五相步进电机,或两相细分型步进电机.
D、换成直流或交流伺服电机,几乎可以完全克服震动和噪声,但成本较高.
E、在电机轴上加磁性阻尼器,市场上已有这种产品,但机械结构改变较大.
