Microstep Motor

The DMX-K-SA-11 all-in-one NEMA-11 microstep motor comes with a driver, controller, and encoder integrated into the motor’s back cap, minimizing external electronics and wiring. The motor uses Renishaw’s magnetic AM256 magnetic encoder chip for real-time position verification. The 16-microstep driver is capable of full, ½, ¼, or 1/16 microsteps in three different stack sizes. The unit is designed for applications requiring a position verification signal from the motor. The electronics inside the back cap have a maximum operating temperature of 85°C (185°F).

The stand-alone control uses Windows-based programming, is easy to program, features RS-485 communication with a baud rate of 9,600 to 115K bps, has a trapezoidal acceleration profile control, 12 to 24-Vdc voltage input, and driver current from 100 mA to 1.5 A.
