32bit motor control kit spins and tunes three-phase brushless motors in minutes
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 software out-of-the-box, along with other customer-developed applications, when plugged into the DRV8312 motor driver base board.
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.
InstaSPIN-BLDC 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.
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, The 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
The kit includes a 24V three-phase BLDC motor operating at up to 3.5A continuous and supporting software includes StellarisWare software with TI’s IQmath Library for easy fixed to floating point conversion. Designers can accelerate system design with an intuitive graphical user interface (GUI) powered by third party Crosshairs Embedded.
