  • Name: MBV
  • Explain:
  • MBV Seires (Miniature bushing voice motor stage) are driven by Akribis' voice motor system, with high frequency motion. It is suitable for high moving frequense and low cost


Design Feature

A. Direct drive

B. Suitable for high speed and acceleration applications

C. For vertical use only


XRV Series (Cross roller voice coil stage) driven by Akribis’ rectangular voice coil motor system, are high precision and fast response stages. It is suitable for minute movement and smooth motion application.


Direct-drive voice motor system

XRV series are driven by Akribis’ rectangular voice coil motor. The advantages of this motor are zero cogging force, very fast response and bandwidth. It is suitable for light weight, high speed and acceleration application.


Precise motion and homing

XRV Series integrate high level precision optical encoder system, which contributes a precise positioning motion for customers.


Low friction

High level precision cross roller linear guide provides low friction and smooth motion, and also contributes to better stiffness.
