Robust Liberty MDrive (LMD) linear motion products integrate either a NEMA 17 or NEMA 23 stepper motor with external shaft linear actuator or captive shaft electric cylinder. Linear motion is produced by ACME screw/nut systems mounted to a motor’s driving shaft. Products include onboard drive electronics and controller with up to 8 I/O. Feedback options include open loop or closed loop with a 1000 line (4000 count/rev) internal incremental or multi-turn absolute encoder with hMT closed loop performance.

This high degree of integration can reduce machine complexity, size and cost in many stepper and servo motor applications. Liberty MDrive delivers exceptional performance and smoothness with advanced current control. Ideal for machine builders who want an optimized motor with onboard electronics.

Captive Shaft Electric Cylinder (eCylinder)

Quiet, clean and compact, LMD eCylinder products deliver distinct benefits, including replacing pneumatics in some applications. These products offer many distinct benefits including competitive price, high accuracy and repeatability.

External Shaft Linear Actuator 

OEMs who want to reduce machine size, cost and complexity will find robust LMD Linear Actuator products deliver exceptional performance and value for many linear motion applications.

Communications and networking

Supported communication protocols include:

  • Ethernet: EtherNet/IP, Profinet, ModbusTCP
  • CANopen
  • RS-422/485
