描述

含CAN的Stellaris刷式直流电机参考设计套件(RDK-BDC)提供了在40 A连续电流上12伏有刷直流电动机变速控制。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.

特性

The Stellaris MDL-BDC is powered by the Stellaris LM3S2616 microcontroller, featuring CAN and advanced motion control capabilities. While the LM3S2616 offers 128 KB of integrated single-cycle Flash memory, the preprogrammed factory source code that ships with the MDL-BDC compiles to less than 16 KB. The LM3S2616 microcontroller's robust combination of features, along with the efficient and deterministic performance of the Cortex?-M3 core, positions the modules into a wide variety of consumer and industrial applications, including factory automation devices and systems, mobile robots, household appliances, pumping and ventilation systems, and electric wheelchairs and mobility devices. The RDK-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
    
         
  
• Limit switch inputs for forward and reverse directions       
  
• Status LED indicates Run, Direction, and Fault conditions       
  
• Motor brake/coast selector       
  
• Quadrature encoder input (QEI) and analog input       
  
• Color-coded screw terminals for all power wiring
