Luminary Micro new Brushless DC Stellaris Reference Design Kit

Austin, Texas, (ANTARA News/PRNewswire-AsiaNet) - Luminary Micro (http://www.LuminaryMicro.com), creators of the award-winning Stellaris(R) family of ARM Cortex(TM)-M3-based microcontrollers (MCUs), today announced the immediate availability of a new Stellaris Reference Design Kit, the Stellaris Brushless DC (BLDC) Motor Control Reference Design Kit (RDK-BLDC) with Ethernet and CAN.

Brushless DC motors offer efficient operation, excellent torque characteristics, and durability, and are particularly suited for use in factory automation, medical instruments, robotics, electric vehicles and mobility devices, pumping and ventilation systems, and small appliances. With built-in Controller Area Network (CAN) and Ethernet interfaces, the RDK-BLDC represents an industry benchmark in the integration of motion control with network-based communication, command, and control.

The Brushless DC Motor Control Reference Design Kit (RDK-BLDC) is a four-quadrant controller for three-phase brushless DC motors rated at up to 36 V, 500 W, and 60,000 RPM. Key features of the RDK include complete CAN and Ethernet network interfaces, a powerful 32-bit Stellaris microcontroller with 256 Kbytes of single-cycle internal flash memory, and embedded software to optimally control a wide range of motors in diverse applications. Reference design kits (RDKs) from Luminary Micro accelerate product development by pairing ready-to-run software and hardware with an included motor, and providing comprehensive documentation with all software source code and hardware design files. Designers without prior motor control experience can successfully implement a sophisticated motor control system using the BLDC RDK.

Integrated CAN and Ethernet ports connect the RDK-BLDC to an array of network options-from dedicated industrial networks to worldwide control and monitoring over the Internet.

"Brushless DC motors are extremely popular because of their precision, quiet operation, and energy efficiency -- and the Stellaris Brushless DC Motor Control Reference Design Kit helps to streamline the complex combination of power, control, and connectivity functions for the benefit of anyone who utilizes the design," said Luminary Micro Chief Marketing Officer Jean Anne Booth. "We make it easy to adopt the Stellaris BLDC control module directly into end products for an extremely fast time-to-production advantage."

Everything Designers Need to Move from Evaluation to Fully Integrated Solution

The RDK-BLDC contains everything required to evaluate and develop brushless DC motor control designs. The kit includes a brushless DC motor control module featuring Luminary Micro's highly-integrated Stellaris LM3S8971 microcontroller with on-chip Ethernet MAC+PHY and CAN, a three-phase brushless DC motor, a graphical control program for Windows(TM), and accompanying cables, source code, and documentation. The Stellaris LM3S8971 microcontroller handles all PWM synthesis, position, and analog sensing as well as Ethernet and CAN networking. Only a few additional power ICs are necessary to complete the design. The entire circuit is built on a simple two-layer printed circuit board.

The design includes an on-board braking circuit, optional power-managed fan for forced-air cooling, analog and digital control inputs, and screw terminals for all power and signal wiring. Interrupt-driven embedded software provides four quadrant operation for precise motor control using Hall effect, quadrature, or sensorless operation modes. The graphical control program allows users to experiment with varying drive parameters and observe the effect on motor performance.

Modular Design Also Available For Direct OEM Use

Luminary Micro also provides the Stellaris BLDC control module as a stand-alone product (MDL-BLDC) available in cost-effective volume quantities, providing OEMs a
production-ready solution to immediately integrate BLDC motor drive controls directly into their respective end products.

Stellaris: Advanced Mechatronics MCUs with Integrated Motion-Specific Hardware

Over half of the 104 Stellaris microcontrollers available from Luminary Micro feature integrated motion-specific capabilities typically found only on costly specialty devices. In addition to a general purpose timer module that can be configured to operate as up to 8 pulse width modulation (PWM) outputs, these Stellaris family members integrate a special motion control module that provides up to six additional channels of PWM with enhancements for real-time motor control.

The motion control module can generate simple PWM signals (such as those required by a simple charge pump), paired PWM signals with dead-band delays (such as those required by a half-H bridge driver), and a full six channels of gate controls (such as those required by a 3-phase inverter bridge). In addition, the motion module provides fault-condition handling to quickly shut down a motor in a low-latency situation. The motion module is complemented by up to two quadrature encoder inputs (QEI), providing precise position sensing for closed-feedback motion control. For detailed information on the features of each Stellaris family member, see the product selector guide (http:/www.LuminaryMicro.com/psg).

Australia`s Clarius Group selects immediacy for new Web dev`t

Balmoral, (ANTARA News/PRNewswire-AsiaNet0 - Immediacy, part of the Mediasurface group (UK, AIM: MSR), announced today that one of Australia's leading recruitment companies, Clarius Group, has selected Immediacy to strengthen its online presence Mediasurface today announced that the award-winning recruitment company, Clarius Group, has selected the Immediacy Web Content Management (WCM) solution to power its corporate and subsidiary websites.

The Group's corporate website http:/www.clarius.com.au was the first of the Group's site to be successfully launched in time to celebrate their success as 'FEMA Recruitment Firm of the Year' for the second year running.

One of Australia's largest ASX-listed recruitment firms, Clarius Group incorporates Alliance, Candle ICT and other leading brands that provide specialist recruitment services to key sectors including accounting, IT and support services. Clarius Group currently operates seven individual websites representing each business unit, including the corporate site http://www.clarius.com.au.

Previously the HTML-driven websites were developed and maintained by the busy in-house IT team, who were also responsible for providing IT services for this expanding agency. As a result the websites were beginning to suffer from static content and technical inconsistencies that were causing a significant fall in click-through.

"The Internet is the ideal medium for job hunting and recruitment. The majority of our business -- particularly candidate attraction -- is generated through our websites and with the old sites our hands were tied. It was extremely difficult for Marketing to make changes or implement new features, such as RSS feeds. We also needed to be able to maintain control of branding and content and with hard-coded HTML, this was simply impossible," explains Stephanie Hardcastle, Group Marketing Manager.

Clarius Group was keen to find a system that would deliver control of the day-to-day running of the sites to Marketing, but also be sufficiently technical to facilitate the introduction of interactive media including RSS feeds and community areas for investors and stakeholders.

Stephanie continues;
"We looked at a variety of different IT systems but were bowled over by the scope of the Immediacy WCM solution. The sales team understood our requirements from the outset and were able to demonstrate how Immediacy would help us support multiple websites from a single platform that we in Marketing could manage and control."

Based on the Microsoft(TM) look and feel, Immediacy has an intuitive interface that means there is minimal training for users. As a result, the team at Clarius were able to start using the product to populate content onto the new corporate website whilst the technical implementation progressed. The speed of the implementation meant that all seven fully branded websites were launched within a matter of weeks.

"The implementation of all sites was incredibly fast thanks to Immediacy's flexibility and ease of use. My Marketing team has been able to update content directly without having to go through IT, and we have been able to design effective
click-through pathways -- which is already having a positive impact on site traffic. In all, Immediacy has proven that we can deliver an exceptional online experience to all of our stakeholders," concludes Stephanie.

Chris Tew, Senior Vice President, Mediasurface Asia Pacific comments: "We are delighted to be working with one of the top Australian recruitment firms. Immediacy WCMs has been ideal for their multi site requirements and will fully support Clarius's ambitions to keep growing their business via the web."

Clarius Group now plans to move its Intranet over to the WCM, and to update its websites using the impressive tools available within the Immediacy system to improve its online presence still further.

Immediacy v6.0 is now available in Australia through the Mediasurface AsiaPac offices based in Sydney.
