Austin, TX (December
12, 2011) – Adding to its growing portfolio of
motor control solutions, Texas Instruments Incorporated (TI) (NYSE:
TXN) today announced
a new motor control kit for spinning three-phase brushless motors with
a
Stellaris® Cortex™-M3 microcontroller (MCU). The new DK-LM3S-DRV8312 motor control kit features a
32-bit
Stellaris LM3S818 microcontroller and DRV8312 motor driver to spin
sub-50V,
6.5A three-phase brushless DC (BLDC) motors in minutes. The easy-to-use
kit is
a low-cost solution for high-volume motor control applications,
including
low-voltage fans, blowers, pumps, tools and compressors. For more
information,
visit www.ti.com/stellaris-motor-pr-lp.
The Stellaris LM3S818
controlCARD module included in the kit has the
required firmware pre-programmed in flash memory to run TI’s new
InstaSPIN-BLDC™ solution out-of-the-box, along with other
customer-developed
applications, when plugged into the DRV8312 motor driver base board. The InstaSPIN-BLDC solution is an innovative and free
back-electromagnetic field (EMF) technique that spins any motor in
seconds
without knowledge of any motor parameters. Unlike traditional back-EMF
zero
crossing techniques, InstaSPIN-BLDC extends sensorless operation down
to lower
speeds and exhibits high immunity to miscommutation caused by rapid
speed
changes. Reliable motor start-up has been demonstrated over a wide
range of
conditions, including full torque.
Features and
benefits of the Stellaris motor control kit:
·
The
controlCARD module with Stellaris LM3S818 MCU features 50 MHz
performance, 64
KB flash, 8 KB SRAM and 6 PWM generators, allowing developers to create
complex
motion control designs with a tiny footprint
·
DRV8312 motor driver provides the highest current
output in
its class, delivering up to 6.5A, without the need for a
costly
external heat sink. It is a reliable, fully protected motor driver with
cycle-by-cycle over-current, over-temperature, cross-conduction and
under-voltage protection, reducing design complexity and board space
and
ensuring higher system reliability
·
Kit includes a 24V three-phase BLDC motor operating at up to 3.5A
continuous
·
Supporting software includes StellarisWare® software with TI’s IQmath Library for easy fixed to floating point
conversion
and InstaSPIN-BLDC software for quick and reliable motor start-up on
any motor
·
Accelerate system
design with intuitive graphical user interface (GUI) powered by third
party
Crosshairs Embedded. Customize the existing GUI or create your own with
easy
drag and drop development by downloading Crosshairs Interface Designer.
Pricing and
availability
Developers can get
started immediately with the DK-LM3S-DRV8312
development kit for $299 USD at www.ti.com/stellaris-motor-pr-es. Those who have
already
purchased the DRV8312-C2-KIT, which includes the DRV8312 and
C2000™
Piccolo™ MCU, can swap out the existing controlCARD with the Stellaris
LM3S818
controlCARD module for $49 USD at www.ti.com/stellaris-motor-pr-es2.
