Stellaris® Brushless DC (BLDC) Motor Control Board with Ethernet and CAN - MDL-BLDC

Not Recommended For New Designs



General Description

The brushless DC (BLDC) motor control board is a four-quadrant motor control board for three-phase BLDC motors rated at up to 36 V (see Figure 1). Key features include complete CAN and Ethernet communications interfaces, the powerful, 32-bit Stellaris® LM3S8971 microcontroller, and sophisticated software to optimally control a range of motors in diverse applications.

10/100 Ethernet connects the BLDC module to an array of networks—from dedicated industrial networks to the internet. The standard BLDC module includes the Stellaris motor control and configuration (MCC) protocol. This protocol can be replaced with any industry-standard protocol.

First-time users should purchase a complete BLDC reference design kit (RDK) which
includes the control board, cables, configuration software (GUI), a documentation CD, and
a sample motor. After evaluating the BLDC module, users may choose to either customize
the design or use the BLDC board without modification.


The MDL-BLDC contains the feature-rich Stellaris LM3S8971 microcontroller with Ethernet and CAN. The MDL-BLDC takes advantage of the integrated features of the Stellaris microcontroller and the processing power of the ARM® Cortex™-M3core to optimally control a wide range of brushless DC motors in diverse applications.


The MDL-BLDC includes the following product features:
  • Advanced motor control for three-phase brushless DC motors
  • Four quadrant operation
  • Hall Effect, Quadrature, and Sensorless operation modes
  • On-board braking circuit
  • Incremental quadrature encoder input
  • Analog and digital control inputs
  • Test mode push-button
  • Status LEDs indicate Power, Run, and Fault conditions
  • Optional power-managed fan for forced-air cooling
  • Screw terminals for all power and signal wiring
  • JTAG/SWD port for software debugging
