RDK-STEPPER: 3A, 80V, Stepper Motor Control

Stellaris Reference Design Kits (RDKs) from Texas Instruments accelerate product development by providing ready-to-run hardware, a typical motor, and comprehensive documentation including hardware design files. Designers without prior motor control experience can successfully implement a sophisticated motor control system using the Stepper Motor Control RDK (Stepper RDK).

The Stepper RDK's primary application is driving NEMA17, NEMA23, and NEMA34 stepper motors rated at up to 80 V at 3 Amps. The Stepper RDK uses software-based chopper control in order to operate the motor at both high torque and high-step rates.

The Stepper RDK has the following features:

• Advanced chopper control of bipolar stepper motors
  

• Flexible platform accelerates integration process
  

• Fast and slow decay modes
  

• Full-Step, Half-Step, Micro-Step, and Wave modes
  

• High step rates up to 10,000 steps/sec (with suitable motor)
  

• Programmable holding current
  

• Integrated USB Virtual COM port
  

• Bootloader for firmware upgrades over serial port
  

• Support for external debugger through standard 20-pin ARM header
