Siemens' Micro Master Vector and Midi Master Vector Variable Frequency Drives (VFDs) are reportedly the first to integrate sensorless vector control into the small dimensions of a standard frequency controller. The two units are smaller in size and offer more standard features than their VFD predecessors. They are also compatible with standard induction motors ranging between 1/6 to 100 hp. Introduced in 1993, the Micro/Midi Master drives were among the first VFDs to offer breakthrough technologies, such as flux current control for automatic current load adaption. In their latest iteration, the controllers' sensorless vector inverter capability derives from a new ASIC that quickly calculates rotor speed and position. This enables the rotor and stator current to be controlled for optimized performance. Siemens Energy & Automation Inc. Product Code 4362 (P)
Enabling the Future is designing prosthetic appendages modeled more like superhero arms and hands than your average static artificial limbs. And they’re doing it through a website and grassroots movement inspired by two men’s design and creation in 2012 of a metal prosthetic for a child in South Africa.
In order to keep an enterprise truly safe from hackers, cyber security has to go all the way down to the device level. Icon Labs is making the point that security has to be built into device components.
Three days after NASA's MAVEN probe reached Mars, India's Mangalyaan probe went into orbit around the red planet. India's first interplanetary mission, and the first successful Mars probe launched by an Asian nation, has a total project cost of nearly $600 million less than MAVEN's.
