Description
The Stellaris Brushed DC Motor Control Module with CAN (RDK-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 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
