AUSTIN, Texas, Dec. 12, 2011 /PRNewswire/ -- 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.
