LSPA30uXS Linear Piezo Motor Developer Kit - 1

LSPA30UXS LINEAR PIEZO MOTOR DEVELOPER KIT PRESENTATION The Linear Stepping Piezo Actuators (LSPA) are long stroke linear piezoelectric motors for high precision positioning. Classified as inertial piezo actuators, they benefit from the APA® heritage, especially from their large deformation and high reliability. LSPA operates by accumulation of small steps (M1), produced by a sawtooth-like signal. Between each step, the motor is locked in position and that, without any consumption. As a complementary mode, fine adjustment (M2) of the APA® allows to reach nanometer resolution. The LSPA30uXS Developer kit offers the possibility to discover the potential of the LSPA30uXS, 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. ■■ Fig1: LSPA30uXS motor components and principle DESCRIPTION OF THE LSPA30UXS DEVELOPER KIT The LSPA30uXS Developer kit is made of different sub-systems: 1) LSPA30uXS kit (SPA30uXS 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 CONFIGURATION AND INTERFACES Copyright © CEDRAT TECHNOLOGIES | Developer_Kit_SPA30uXS - 02/2014 The Developer kit is a plug and play solution. It allows to learn quickly how to use the SPA motor. The LSPA30uXS motor can be extracted from the holding platform and integrated directly onto user’s test bench. ■■ Fig3: Mechanical configuration with fixed (orange) and mobile (blue) parts of the motor
