Luminary Micro's New Brushless DC (BLDC) Stellaris(R) Reference Design Kit Provides Networked Motion Control OEMs with a Time-to-Production Edge

    Complete Kit Shows Unprecedented Integration of Brushless DC Motion
    and Industrial Networking

    AUSTIN, Texas, Jan. 15 /CNW/ -- Luminary Micro
(, creators of the award-winning Stellaris(R)
family of ARM Cortex(TM)-M3-based microcontrollers (MCUs), today announced the
immediate availability of a new Stellaris Reference Design Kit, the Stellaris
Brushless DC (BLDC) Motor Control Reference Design Kit (RDK-BLDC) with
Ethernet and CAN.  Brushless DC motors offer efficient operation, excellent
torque characteristics, and durability, and are particularly suited for use in
factory automation, medical instruments, robotics, electric vehicles and
mobility devices, pumping and ventilation systems, and small appliances.  With
built-in Controller Area Network (CAN) and Ethernet interfaces, the RDK-BLDC
represents an industry benchmark in the integration of motion control with
network-based communication, command, and control.
    The Brushless DC Motor Control Reference Design Kit (RDK-BLDC) is a
four-quadrant controller for three-phase brushless DC motors rated at up to 36
V, 500 W, and 60,000 RPM. Key features of the RDK include complete CAN and
Ethernet network interfaces, a powerful 32-bit Stellaris microcontroller with
256 Kbytes of single-cycle internal flash memory, and embedded software to
optimally control a wide range of motors in diverse applications.  Reference
design kits (RDKs) from Luminary Micro accelerate product development by
pairing ready-to-run software and hardware with an included motor, and
providing comprehensive documentation with all software source code and
hardware design files. Designers without prior motor control experience can
successfully implement a sophisticated motor control system using the BLDC
RDK.  Integrated CAN and Ethernet ports connect the RDK-BLDC to an array of
network options-from dedicated industrial networks to worldwide control and
monitoring over the Internet.
    "Brushless DC motors are extremely popular because of their precision,
quiet operation, and energy efficiency -- and the Stellaris Brushless DC Motor
Control Reference Design Kit helps to streamline the complex combination of
power, control, and connectivity functions for the benefit of anyone who
utilizes the design," said Luminary Micro Chief Marketing Officer Jean Anne
Booth. "We make it easy to adopt the Stellaris BLDC control module directly
into end products for an extremely fast time-to-production advantage."
    Everything Designers Need to Move from Evaluation to Fully Integrated
    The RDK-BLDC contains everything required to evaluate and develop
brushless DC motor control designs.  The kit includes a brushless DC motor
control module featuring Luminary Micro's highly-integrated Stellaris LM3S8971
microcontroller with on-chip Ethernet MAC+PHY and CAN, a three-phase brushless
DC motor, a graphical control program for Windows(TM), and accompanying
cables, source code, and documentation. The Stellaris LM3S8971 microcontroller
handles all PWM synthesis, position, and analog sensing as well as Ethernet
and CAN networking. Only a few additional power ICs are necessary to complete
the design. The entire circuit is built on a simple two-layer printed circuit
board. The design includes an on-board braking circuit, optional power-managed
fan for forced-air cooling, analog and digital control inputs, and screw
terminals for all power and signal wiring.  Interrupt-driven embedded software
provides four quadrant operation for precise motor control using Hall effect,
quadrature, or sensorless operation modes.  The graphical control program
allows users to experiment with varying drive parameters and observe the
effect on motor performance.
    Modular Design Also Available For Direct OEM Use
    Luminary Micro also provides the Stellaris BLDC control module as a
stand-alone product (MDL-BLDC) available in cost-effective volume quantities,
providing OEMs a production-ready solution to immediately integrate BLDC motor
drive controls directly into their respective end products.
    Stellaris:  Advanced Mechatronics MCUs with Integrated Motion-Specific
    Over half of the 104 Stellaris microcontrollers available from Luminary
Micro feature integrated motion-specific capabilities typically found only on
costly specialty devices.  In addition to a general purpose timer module that
can be configured to operate as up to 8 pulse width modulation (PWM) outputs,
these Stellaris family members integrate a special motion control module that
provides up to six additional channels of PWM with enhancements for real-time
motor control.  The motion control module can generate simple PWM signals
(such as those required by a simple charge pump), paired PWM signals with
dead-band delays (such as those required by a half-H bridge driver), and a
full six channels of gate controls (such as those required by a 3-phase
inverter bridge).  In addition, the motion module provides fault-condition
handling to quickly shut down a motor in a low-latency situation.  The motion
module is complemented by up to two quadrature encoder inputs (QEI), providing
precise position sensing for closed-feedback motion control.  For detailed
information on the features of each Stellaris family member, see the product
