Stepper motors are the engines of choice for belt control or mult-axis machine control - or would be if controlling was simpler. A new type of controller might make it possible to get rid of more expensive motors and facilitate regulation.
In order to comply with the standards ISO 13849 and IEC 62061, the PLD manufacturer Altera has chosen to cooperate with the TÜV Rheinland: Together with this German safety certification body, the company has created a pre-qualified development tool chain, including safety manuals and safety intellectual property (IP) cores for its FPGAs. The TÜV-qualified industrial safety data package for automation applications may speed up development time for at least two years, says Frank Förster, Market Development Manager Industrial at Altera confidently.
When you are a marketing person with a really phat slogan, you are definitely allowed to repeat it as often as you like in order to convey your message and, of course, to demonstrate your wits. Often, the slogan is not as brilliant as Mr. or Ms. Marketing thinks and they bore everyone to death by hammering it into their victims’ brains. A third type takes a motto which may have been inventive at the time when the meteorite killed off the dinosaurs, repeats it in every other sentence and wonders why his audience stops listening. “No compromise” were not only the last words of T-Rex looking at the sky but also the only point Actel made during its announcement of their Mixed-Signal FPGAs called “SmartFusion”. These devices use ARM’s Cortex M3 processor and a programmable analog array. Possible applications encompass motor control, system management, power management and industrial networking.
“We want to provide a complete and cost-effective solution”, states Jürgen Hoika. The Director Marketing Microcontroller Industrial and Multimarket at Infineon Technologies is convinced that the two new Low-Cost 8-Bit MCU series will fit well into applications like energy efficient designs of drives, automation, lighting solutions, and Human Machine Interfaces (HMI).
For the experts of embedding computing the upcoming trade show embedded world 2010 may be a special highlight: The venue not only sets standards and records every year. Despite the difficult economic conditions, the industry’s international get-together continues to grow with innovation that reflects the dynamic of this market.
With oil companies drilling deeper than ever before to obtain increasingly valuable deposits, components within the drill tool must deliver reliable operation at the most extreme ambient temperatures. This is also valid for data acquisition components which conduct so called "Down Hole Measurement While Drilling" (MWD) applications.
Electronic products keep shrinking, packages become more and more compact. Along goes the necessity for smaller components. The same is true in electromechanical systems that require miniature motors: Without advanced nanotechnology, physics poses some limitations to the miniaturization of motors; hence the aim is to make everything else as small as possible. One example are the encoders..
Soft at the start and high on torque is the promise Eaton Moeller is making to users of the soft starter switchgear DS7, which is part of the “xStart” system. All components in this series fit together thanks to the toolless plug connections, ensuring simple connection and wiring with other switching devices such as motor-protective circuitbreakers or motor protective relays.
