Texas Instruments introduced their DK-LM3S-DRV8312 motor control kit. It is designed for spinning three-phase brushless motors with a Stellaris Cortex-M3 microcontroller (MCU). The DK-LM3S-DRV8312 development kit is available now. It is an ideal solution for high-volume motor control applications, including low-voltage fans, blowers, pumps, tools and compressors.
The TI DK-LM3S-DRV8312 motor control kit includes 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 included Stellaris LM3S818 controlCARD module 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 uses a 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 miscommunication caused by rapid speed changes.
