Piezo motor technology: Questions answered
There's a new kind of piezo motor in town, and it's got legs. The Piezo LEGS rotational motor is a direct-friction drive that provides precise motion without any mechanical play or backlash. There are no gears or transmission, so changing the direction of the motion will introduce no error. The simple Piezo LEGS motor is also extremely stiff. Find out the answers to frequently asked questions about this exciting motor technology available from the FAULHABER Group.

Largest autonomous mobile robot can lift 1 metric ton
At the Automate 2019 Show and Conference, Mobile Industrial Robots launched the MiR1000, the company's largest autonomous mobile robot (AMR). This mobile platform can automatically pick up, transport, and deliver pallets and other heavy loads up to 1,000 kg (2,200 lb) through dynamic environments. Like the MiR500 introduced in 2018, the MiR1000 is a collaborative, safe, and flexible alternative to potentially dangerous and expensive forklifts on the factory floor. MiR also released another industry first -- artificial intelligence (AI) capabilities across all of its AMRs for improved navigation.
Top Roller conveyor for mobile industrial robots

It provides 32 in. of travel (813 mm). The stage achieves high velocities to 79 in./sec (2 m/sec) based on a direct-drive ironless linear servo motor. High accuracy, repeatability, and functionality are guaranteed by an integrated absolute-measuring linear position encoder featuring 1-nm sensor resolution. Applications include: pick and place, optics, semiconductor test and inspection, bio-tech, DNA sequencing, 3D printing, and laser processing and machining.
More stopping power for servo motors -- using less space
Miki Pulley's BXR-LE spring-applied Electro-Magnetic brake series safely holds a static position, without the need for external power. When the stator is energized, the brake is disengaged allowing free rotation. When no current is applied, compression springs halt the brake rotor, thereby stopping the input shaft rotation. This is an ideal feature to prevent rotation during power failure events. There are six total size configurations in the BXR-LE series to choose from. Of particular importance: These brakes have a slim design and high holding torque in a very compact package. Great for robotics.
Variable frequency drives benefit constant speed applications
Using a variable frequency drive (VFD) can be beneficial in many constant speed applications driven by electric motors, such as those that require controlled starting and have been historically served by a reduced-voltage soft-starter (RVSS). While an RVSS and a VFD can both provide a controlled start, let's examine the benefits of each technology and when it makes sense to use one over the other.

Houston students prepare to face off with their fuel-efficient vehicles at Shell Eco-marathon Americas
The stakes are high in Houston as four high schools and universities prepare for Shell Eco-marathon Americas. St. John's High School and the University of Houston are competing again this year, and, for the first time, Westside High School and Rice University are also getting ready to compete.

They and more than 1,000 other high school and university students across the Americas are preparing for the sixth-annual Shell Eco-marathon Americas taking place at the end of March. Shell Eco-marathon challenges students to build, design, and compete with their high-mileage vehicles in competitions held annually in Europe, the Americas, and Asia. Shell Eco-marathon brings together future leaders in science and engineering who are passionate about finding solutions to global energy challenges.
At the University of Houston, the Superleggera team expects its entry to achieve the equivalent of 1,000 mpg. "We want our vehicle to represent the school well and start a legacy that can be continued by future teams," says Superleggera team leader Jose Guerrero. "We also hope that one day soon, our school can claim the number one spot - not only at Shell Eco-marathon Americas - but among all the Houston schools competing!"
"This is our first year participating in Shell Eco-marathon Americas, and we are excited to show everyone, especially the University of Houston, just what Rice University can do," says Andrew Owens of the Rice Solar Car team. "Our two universities have a long-standing rivalry between them, and we'd love to bring a win home to Rice, especially when it involves the future of energy."
From March 29 through April 1, students and their fuel-efficient vehicles will navigate the streets of downtown Houston, amid the skyscrapers, and strive to break the astounding 2,564.8 mpg (one gallon, that is) achieved in 2011 by Quebec's Universite Laval team, which will compete again this year.
That far outperformed the 50 mpg attained by a Shell scientist in 1939 in a challenge that has evolved into today's Shell Eco-marathon. Since then, the event has brought together thousands of students from more than 30 countries to put their futuristic vehicles to the test.
For first-time competitors from Rice University, participating in this year's event goes beyond what number the team places in the challenge. "Our participation involves motivating and educating students through a large-scale, interdisciplinary, hands-on project in which students can collaborate to create something spectacular," says Rice Solar Car team spokesman Robert Wilson. "We hope to introduce students to the fun side of engineering by allowing them to practice some of the skills they've developed in their classes and build something they can be proud of."
"By encouraging students around the world to design, build, and test vehicles that travel farther using less energy, Shell Eco-marathon provides an education platform for students to apply real-life skills to meet the increasing demand for energy," says Mark Singer, Shell global project manager. "These students and their innovative ideas can help shape the future of energy."
Shell Eco-marathon Americas is family friendly, free, and open to the public, so spectators can come out to watch and cheer on the teams. There will be a variety of activities and displays on hand at Discovery Green and George R. Brown Convention Center.
In addition to the student competition, Shell, along with media sponsor The New York Times, will host the 2012 Energy Summit: Earth 2050: The Nexus of Food, Energy, Water. The two-day symposium will be attended by a variety of leaders representing policy, the environment, business, and academia.
Shell Eco-marathon Americas coincides with another key Shell community event, the 2012 Shell Houston Open, which will be played the week of March 26 - April 1 at Redstone Golf Club-Tournament course. Phil Mickelson is defending champion. Visit www.ShellHoustonOpen.com for details.
