美国Piezotechnics 压电堆栈,尺寸可定制,用于高精度定位

美国Piezotechnics 压电堆栈

Multilayer piezo stacks. Low voltage type. Produced with co-fired manufacturing technique. Thin coating type.

美国Piezotechnics 压电堆栈有多种形状和尺寸,从1 x 1到25 x 25 mm2不等。它们由电并联的堆叠压电板组成。

Piezotechnics 压电堆栈标称工作电压为0至150 V。这些致动器是“低压压电致动器”。Piezotechnics 压电堆栈还允许具有高达30V至150V的扩展驱动器电压范围的半双极操作。这种操作方法导致明显更大的位移。

裸堆栈非常适合集成到自定义机制中。当与其他致动器类型(如在相同力下的液压缸)相比时,压电堆栈通常具有较小的尺寸。Alos接口非常简单。压电堆栈是长方体,并且具有两根电线来控制元件。带有预应力机构的封装执行器是实现稳健系统集成的理想解决方案。

Piezotechnics 压电堆栈可以在极端环境中运行。适用于在低温、真空和外来环境(如高g场或振动)中操作。

有多种堆叠尺寸和选项可供选择。共烧多层压电堆的最大工作电压为150V。该堆的特点是高功率密度,为您的应用提供强大、精确和快速的驱动。Piezotechnics 压电堆栈允许在-30 V至150 V的电压下进行半双极操作。

Piezotechnics 压电堆栈主要可选:低温,真空,薄涂层,厚涂层,蓝宝石半球,应变仪。

美国Piezotechnics 压电堆栈标准型号如下,也可定制其他尺寸。
