CEDRAT TECHNOLOGIES公司开发标准的和定制的LSPA或RSPA压电马达和SPS机动平台。
这些技术是通过小步长的累加而成。促动器在各步长之间是锁定的。执行长行程时,它也可以在运用变形模式进行微调操作。在这种情况下,行程正比于施加的电压,能达到纳米分辨率和高带宽。
步进式压电电机有性价比高的标准产品。CEDRAT TECHNOLOGIES还提供开发套件,用于简易快速的原型机制造,包括一个电机,一个传感器和一个控制器。
CEDRAT TECHNOLOGIES也开发一些定制的SPA,以满足不同环境(医疗MRI,太空...)和客户的需求。在压电电机技术部分或在我们的出版物中有对定制的SPA压电电机的介绍。
Fine Stepping Piezo Actuator (FSPA35XS) is a patented actuator that combines SPA technology with mechanical reduction. Step sizes lower than 100nm are achievable in fine displacement. Typical max speed for this FSPA is 200 um/s.
Actuation force: >100N; Travel range: 5mm; Typical lifetime: 100 cycles
Micro/Nano positioning, locking mechanism
Preliminary
MSPA is a module that provides unlimited motion in both rotation and translation. Since it's a module it easily fits any existing devices requiring 0.3 N of driving force.
Volume= 2 cm³; Max speed: 50 mm/s; Max driving force: 0.3 N; Lifetime more than 2 km
amagnetic; vacuum
Preliminary
MSPA is a module that provides unlimited motion in both rotation and translation. Since it's a module it easily fits any existing devices requiring 1 N of driving force.
Volume= 7 cm³; Max speed: 20 mm/s; Max driving force: 1 N; Lifetime more than 2 km
