The MDrive Hybrid 34AC Step, Torque, Speed offers systems designers a NEMA 34 high torque 1.8 degree step motor integrated with a high resolution microstepping driver with four operational modes. The motor possesses up to 750 oz-in of holding torque and is available in three stack lengths. The AC model features a built in 120 or 240 VAC power supply.This model also features Hybrid Technology which continually monitors the relationship between a step motor's rotor and stator at sub-microsecond intervals, and will not allow that relationship to exceed the point where synchronization is lost.

All-inclusive QuickStart Kits facilitate rapid design verification by bundling MDrive products with everything needed to connect quickly and conveniently, enabling engineers to confirm with confidence that their application’s design goals are met.
QuickStart Kits include: a single sheet instruction guide, software/manuals CD, and connection cabling including Communication Converter and Prototype Development Cable(s).
Order QuickStart Kits simply by placing a "K" at the beginning of an MDrive part number.
Connecting an MDrive has never been easier with readily available Communications Converters and Prototype Development Cables, in addition to Mating Connector Kits for use in building your own cables. Select the "Connectivity solutions" tab above for details on these connectivity options.
An internal differential magnetic encoder with index mark is included with signals made available for external use. Resolutions from 100 to 1000 lines are available. Note: Hybrid control performance is optimized at the higher resolution selections.
