Luminary Micro Announces Motion Control Reference Design Kits for Stellaris(R) Microcontrollers Based on ARM(R) Cortex(TM)-M3



    
    Complete Kits Demonstrate World's First Real-Time Integrated Motion
Control
    Using the ARM(R) Architecture for Multi-Billion Dollar Motion-Control
    Industry
    

    AUSTIN, Texas, April 3 /CNW/ -- Luminary Micro
(http://www.luminarymicro.com), a fabless semiconductor company that designs,
markets, and sells award-winning ARM(R) Cortex(TM)-M3 processor-based
microcontrollers and was the first to bring ARM processor-based MCUs for $1.00
to embedded developers, announced today the availability of two new Reference
Design Kits (RDKs) utilizing the company's Stellaris(R) microcontrollers
(MCUs) designed specifically for motion control applications such as those
found in HVAC systems, industrial conveyer systems, liquid pumps, printers,
robots, and CNC and other milling machines. The two kits demonstrate variable
speed AC induction motor control and stepper motor control, and complement the
recent launch of five new Stellaris MCUs featuring powerful motion control
functionality. These new parts represent the first time that real-time motion
control has been integrated into an ARM-based MCU.  Together with the new
reference design kits, the new MCUs ease the complexity of motion control
designs for OEMs and slash the associated time-to-market and software
development costs.
    The power subsystem for each motion control design features power
semiconductors from Fairchild Semiconductor.  The reference design kits are
available now from Luminary Micro (http://www.luminarymicro.com/sales).
    "The motion control industry is a 'nearly invisible' industry, in that it
is ubiquitous in everyday applications but nearly unseen.  While many
recognize that power and control must come together for the basic functions of
motor control, the complexity of optimizing those functions together is often
underestimated," said Luminary Chief Marketing Officer Jean Anne Booth. "So
while the market potential is great, the challenges facing motion control OEMs
are even greater: energy efficiency, complexity of applications,
time-to-market, and software development costs. Bringing an ARM architecture
to the motion control industry, and particularly the Stellaris implementations
of the Cortex-M3 architecture, addresses not just one of these challenges, but
all of them.   For this reason, Stellaris is rapidly becoming the MCU of
choice for motion control OEMs."

    
    Reference Design Kit for AC Induction Motors (RDK-ACIM)
    
    AC induction motors are widely used in appliance and residential
applications, in what the industry traditionally refers to as "white goods."
The reliability and simplicity of AC motors also makes them popular in
industrial applications, such as residential and light commercial HVAC.
Stellaris microcontrollers enable advanced variable speed control that
improves efficiency and enables new areas of application. The RDK-ACIM design
features a Stellaris LM3S818 microcontroller and drives three-phase AC
induction motors up to 1 HP (750 W), and can scale for motors up to 10 HP.
    Consumer preference and governmental mandates for energy efficiency are
driving the need for more computationally complex control algorithms for
variable speed AC induction motors.  The space vector modulation implemented
in the AC induction motor reference design increases motor efficiency to
nearly 100%, thereby consuming significantly less power.
    "Reducing energy consumption has become a global concern, with the United
States and China as the largest consumers of energy in the world," added
Luminary's Booth.  "More than half of the worldwide electrical output is used
to generate motion, and with overall consumption projected to increase
dramatically over the next two decades, designing with an energy-efficient,
fully integrated MCU with an ARM core, combined with energy management,
appeals to OEMs struggling to meet government mandates for energy efficiency
improvements."

    
    Stepper Motor Control Reference Design Kit (RDK-Stepper)
    
    Stepper motors are widely used in printers, scanners, and automation
applications. One of the few classes of motor that features high starting
torque and precise motion without the aid of sensors, the stepper motor's
unique capabilities have established it as the motor of choice in countless
electronic and automation products. The RDK-Stepper demonstrates advanced
control of bipolar stepper motors using the Stellaris LM3S617 microcontroller
and Fairchild power semiconductors. Its primary application is driving NEMA17,
NEMA23, and NEMA34 stepper motors rated at up to 80 V at 3 Amps.
    Stepper motors are usually controlled either by a dedicated control chip
that lacks programmable intelligence, or by a microcontroller, such as
Stellaris, that uses a basic unipolar scheme. Luminary Micro's stepper motor
reference design performs direct high-performance software-based chopper
control using the Cortex-M3 microprocessor, enabling the designer to add
additional software features without compromising motor performance.

    Everything Designers Need to Move from Evaluation to Fully Integrated
Solution
    Both the RDK-ACIM and the RDK-Stepper feature everything needed to
evaluate and develop motor control designs.  Both kits include the main
control circuit board, graphical control program for Windows(TM), power and
USB cables, quick start guide, software source code, schematics, BOM, and
Gerber files.  The AC Induction Motor reference design includes an
Inverter-Duty 1/4 HP 3-phase AC Motor (0-5400 RPM).  The Stepper Motor
reference design kit includes a NEMA23 Stepper Motor.   Both kits ship with
multiple motion control algorithms loaded into flash, enabling engineers to
evaluate motor and system performance through the graphical user interface
(GUI) within 10 minutes of opening the box.   The GUI allows designers to
configure motor capabilities and safety parameters, test controls and effects,
and to understand tradeoffs in the end motor system design.  The GUI also
allows users to monitor system statistics easily, with visual indicators
showing processor performance, bus voltage, and motor currents.

    
    The Motion Control Story Featuring Luminary Micro and Stellaris
    
    The five new Stellaris family members were announced in February 2007 at
the Embedded World trade show in Nuremberg, Germany, and have been optimized
to support the complex algorithms necessary for efficient energy-saving motion
control applications.  The MCUs are referenced by part numbers LM3S317,
LM3S617, LM3S618, LM3S817, and LM3S818. As with all Stellaris family members,
these MCUs are based on the ARM Cortex-M3 processor -- the microcontroller
member of the ARM Cortex processor family.  Designed for serious
microcontroller applications, the Stellaris family provides entry into the
industry's strongest ecosystem, with code compatibility ranging from $1 to 1
GHz.   Additional advantages include:

    
    -- Easy and cost-effective to upgrade from 8- and 16-bit applications,
       requiring less flash code space and delivering a 10x improvement in
       performance over 8051 cores and an 8x improvement in performance over
       PIC24F cores;

    -- Extensions to the ARM7(TM) family processor capabilities in critical
       MCU applications with a 4x improvement in control processing
       performance, real-time interrupt response capability, and predictable
       deterministic interrupt behavior, while requiring just half the flash
       (code space) of ARM7 control applications;

    -- Greater than 50 MIPS with a demonstrable 20x performance roadmap in the
       Cortex processor family, allowing for a "no-worry" migration path; and

    -- Best-in-industry development environment and debug tools.
    

    The collaboration with Fairchild Semiconductor brings Fairchild's Power
Franchise(R) to each reference design kit. Long recognized as a world leader
in high performance semiconductors, Fairchild specializes in products that
optimize system power and that are ideal for the energy restrictions that
challenge OEMs when developing today's motor applications.
