MDrive integrated intelligent motors

Robust Liberty* MDrive products integrate 1.8° 2-phase stepper motors with onboard drive electronics, a controller with up to 8 I/O.

Feedback options include open loop, or closed loop with a 1000 line (4000 counts/rev) incremental or multi-turn absolute encoder. Both encoder options feature 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 on-board electronics, Liberty MDrive products are well suited for industrial applications.
Supported communication protocols include:

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

*Previously Lexium
