Luminary Micro’s Stellaris Brushed DC Motor Control Module with CAN (MDL-BDC) offers a variable speed control for 12 V brushed DC motors at up to 40 A continuous current. The motor control module includes high performance Controller Area Network (CAN) connectivity and a rich set of control options and sensor interfaces, including analog and quadrature encoder interfaces. The high-frequency PWM on the BDC module enables DC motors to run smoothly and quietly over a wide speed range. The module uses highly optimized software and a powerful 32-bit Stellaris microcontroller to implement open-loop speed control as well as closed-loop control of speed, position, or motor current.

Features:

The MDL-BDC includes the following product features:

• Quiet control of brushed DC motors
  • 15 kHz PWM frequency
• Two options for Speed control
  • Industry-standard R-C servo type (PWM) interface
  • Controller Area Network (CAN) interface
• CAN communication
  • Full configurability of module options
  • Real-time monitoring of current, voltage, speed, and other parameters
  • Load firmware over CAN
• Motor brake/coast selector
• Limit switch inputs for forward and reverse directions
• Status LED indicates Run, Direction, and Fault conditions
• Quadrature encoder input (QEI) and analog input
• Color-coded screw terminals for all power wiring
• Easy to customize using tools supporting the MDL-BDC from Keil, IAR, Code Sourcery, or Code Red (using a Stellaris evaluation kit or preferred ARM® Cortex™-M3 debugger)
