CEDRAT LSPA30uXS Developer's Kit

CEDRAT Piezoelectric Technologies

Linear Stepping Piezo Actuators (LSPA) are long stroke linear piezoelectric motors for high precision positioning. Classified as inertial linear piezo motors, they benefit from the Cedrat APA® - Ampllified Piezoelectric Actuators - heritage, specially from their large deformation and high reliability.

SPA30uXS Motor - Operation

SPA operates by accumulation of small steps (M1), produced by a sawtooth-like signal. Between each step, the motor is locked in the new position without any consumption. As a complementary mode, fine adjustment (M2) of the APA® allows it to reach nanometer resolution.

Description of the LSPA30uXS Developer Kit

The LSPA30uXS Developer kit offers the possibility to discover the potential of the SPA30uXS, smallest existing LSPA, in stepping mode (M1). With an external dedicated miniature driver (SPC45), and coupled to a high resolution magnetic sensor, the Developer kit is a fully closed-loop solution for high resolution millimetric motion.
The LSPA30uXS Developer kit is made of different sub-systems:
  • 1- SPA30uXS kit (LSPA30uXS motor coupled with an incremental sensor on a holding platform)
  • 2- SPC45 driver
  • 3- SPC45 Power Supply
  • 4- Cables
  • 5- USB cable for GUI control

Mechanical configurations and interfaces

The Developer kit is a plug and play solution. It allows for quickly learning how to use the LSPA motor.
The LSPA30uXS motor can be extracted from the holding platform and integrated directly onto user’s test bench.
