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.
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.
