Evaluation platform drives 3-phase brushless motors for quicker time to spin
Texas Instruments’ out-of-the-box motor control solution speeds development of brushless DC, permanent magnet synchronous motors.
Texas Instruments Incorporated introduced a complete motor control evaluation kit for spinning brushless dc (BLDC) and permanent magnet synchronous (PMSM) motors. The DRV8312-C2-KIT is a high-performance, power-efficient and cost-effective sensorless field-oriented control (FOC) and trapezoidal commutation platform. It spins motors out of the box, speeding development of sub-50-V and 6.5-A brushless motors for driving medical pumps, gates, lifts and small pumps, as well as industrial and consumer robotics and automation.
Key features and benefits:
- Out-of-the-box motor control and driver solution includes the DRV8312 motor driver, a 32-bit C2000 Piccolo microcontroller (MCU) controlCARD module, a quick-start graphical user interface, full development source code, Code Composer Studio (CCStudio) integrated development environment (IDE) and a three-phase BLDC motor.
- Flexible control platform that supports sensorless FOC, and sensorless and sensored trapezoidal commutation control for rapid evaluation and development of three-phase motors. By adding a separate shaft encoder, the DRV8312-C2-KIT can also support sensored FOC.
- DRV8312 three-phase, fractional-horsepower motor driver provides the highest current output in its class, delivering up to 6.5 A, without the need for a costly external heat sink. The DRV8312 motor driver is robust, reliable and fully protected 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.
- C2000 Piccolo MCU performs control, communications, and debug functions. The industry-leading 32-bit C2000 MCU integrates the most advanced analog feedback, digital control peripherals and CPU capability in an embedded MCU device family starting under $2. This includes access to the most thorough set of motor control software modules, real-time debug capabilities, and open-tooled reference designs via free controlSUITE software.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
