Courtesy: Texas InstrumentsTexas Instruments Incorporated (NYSE: TXN) announced a motor control kit for spinning three-phase brushless motors with a Stellaris Cortex-M3 microcontroller (MCU). The DK-LM3S-DRV8312 motor control kit features a 32-bit Stellaris LM3S818 microcontroller and DRV8312 motor driver to spin sub-50 V, 6.5 A three-phase brushless dc (BLDC) motors in minutes. This solution is 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 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.

Features and benefits of the Stellaris motor control kit include:

  • 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.
  • DRV8312 motor driver provides output up to 6.5 A, without the need for a costly external heat sink. It is a fully protected motor driver with cycle-by-cycle over-current, over-temperature, cross-conduction and under-voltage protection, reducing design complexity and board space.
  • Kit includes a 24 V three-phase BLDC motor operating at up to 3.5 A continuously.
  • Supporting software includes StellarisWare software with TI’s IQmath Library for easy fixed to floating point conversion and InstaSpin-BLDC software for quick and reliable motor start-up on any motor.
  • Accelerated system design with intuitive graphical user interface (GUI).

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
