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.

Top Tech Tip: Specifying self-lubricating bearings for linear motion systems

Self-lubricating ball bushing bearings have experienced an increase in use among motion system designers thanks to their ability to significantly reduce cost of ownership, improve performance, and deliver virtually maintenance-free operation. However, these bearings may not reach their full potential without being properly specified, installed, and evaluated for compatibility with their intended environment. Learn how to specify them for long-lasting use in your motion system applications.

New long-travel linear motor stage

The new V-417.336025E1 linear translation stage from PI is engineered for industrial applications with high demands on dynamics, precision, smooth scan motion, short settling times, and low tracking error. 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.

How a Seventh Axis adaptation aims to move cobot technology into more factories

Advances in technology and software are expanding the scope of potential cobot work environments to include small and mid-size operations. That's why Rollon Corporation has created a Seventh Axis system for collaborative industrial robots from Universal Robots (UR). This shuttle system is designed to extend the operating area of UR's cobots to enhance their performance in automated processes for various industries without sacrificing their simplicity.

Ford to develop electric vehicle based on Rivian's flexible skateboard platform, invests $500M in company

Do you remember that super-cool Rivian all-electric pickup we featured in Designfax last December? Ford Motor Co. has made a $500 million equity investment in Rivian, and the two companies have agreed to work together to develop an all-new, next-generation battery electric vehicle for Ford's growing EV portfolio using Rivian's skateboard platform.

Rivian, a new-kid-on-the-block electric vehicle manufacturer, introduced its R1T, an all-electric, five-passenger pickup at the LA Auto Show in December 2018. Featuring a tailored and restrained design, the truck boasts a range of up to 400+ miles, a wading depth of 1 m, quad-motor AWD that does 0 to 60 mph in 3 sec, and a totally unique skateboard platform with lots of storage.

Rivian has development centers in Plymouth, MI; San Jose, CA; Irvine, CA; and the UK. The company will produce vehicles at its modern, 2.6-million-sq-ft manufacturing plant in Normal, IL. First delivery target is late 2020.

Rivian is also developing a seven-passenger SUV called the R1S.

"As we continue in our transformation of Ford with new forms of intelligent vehicles and propulsion, this partnership with Rivian brings a fresh approach to both," said Jim Hackett, Ford president and CEO. "At the same time, we believe Rivian can benefit from Ford's industrial expertise and resources."

As part of a previously announced $11 billion EV investment, Ford already has confirmed two key, fully electric vehicles: a Mustang-inspired crossover coming in 2020 and a zero-emissions version of the best-selling F-150 pickup.

Rivian will remain an independent company. The investment is subject to customary regulatory approval. Following Ford's investment, Joe Hinrichs, Ford's president of Automotive, will join Rivian's seven-member board.
