TI speeds motor design with ARM MCU-based kits
Texas Instruments has a range of motor control kits for quick designs with three-phase brushless DC (BLDC) motors.
The four motor control kits include object-oriented software functions and drivers for TI’s Stellaris and Hercules ARM-based MCUs and motor driver families.
Each motor control kit includes a protected motor driver monitoring cycle-by-cycle over-current, over-temperature, cross-conduction and under-voltage situations.
A plug-in controlCARD module lets developers choose the right combination of motor driver for voltage, current and experimentation with different MCUs for control.
The kits come with the required firmware to run TI’s sensorless InstaSPIN-BLDC motor control software solution out-of-the-box. InstaSPIN-BLDC is an innovative and free back-electromagnetic field (EMF) technique that sensorlessly spins any motor in seconds without knowledge of a motor’s parameters.
The Stellaris kit also includes a sensorless sliding mode observer (SMO) field oriented control (FOC) speed plus torque control application while the Hercules kits add firmware for sensored (encoder) speed plus torque control with SMO as sensorless redundancy for safety systems.
The MSP430 DRV8312-430FR-KIT motor control kit incorporates a controlCARD module with MSP430FR5739 MCU, 16KB FRAM, five 16-bit timers and 10-bit ADC.
The Hercules DRV8301-LS31-KIT (TMS570) and DRV8301-RM48-KIT (RM4x) safe motor control kits include a controlCARD module featuring a dual core, lock-step Hercules ARM Cortex-R4F safety MCU with floating point with up to 220MHz performance, 3MB of flash.
The Hercules DRV8301-LS31-KIT and DRV8301-RM48-KIT safe motor control kits are $499 and include the Teknic servo motor and a 24V power supply.
The MSP430 DRV8312-430FR-KIT and Stellaris DK-LM4F-DRV8312 kits are available for purchase for $299 and include a 24V NEMA17 BLDC motor with hall sensors and 24V power supply.
Developers with a compatible motor driver base can also buy the Hercules TMDX570LS31CNCD or TMDXRM48CNCD controlCARD modules for $99.
The MSP430 MSP-CNCD-FR5739 and Stellaris MDL-LM4F211CNCD controlCARD modules are available separately for $49.
