Why convert hydraulics to electric high-force linear actuators?

Got a high-force linear motion application? If you do, chances are the first product solution to come to mind is hydraulic cylinders. They're relatively inexpensive (if you already have a hydraulic power unit in place), compact (if the HPU is somewhere else), and power-dense. But what about the disadvantages -- leaks, operation and maintenance costs, and more? It's possible to convert an application from hydraulic to electric linear motion easily, and Tolomatic even gives you step-by-step instructions.

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.

Next-gen permanent magnet AC motor with integrated encoder

Designed for today's demanding machine drive applications, the new VFsync synchronous AC motors from Bison Gear and Engineering run at high efficiency with advanced variable frequency drives. These IP66/IP54 platform motors were optimized with FEA software and then tooled with highly efficient internal permanent magnet-style rotors. VFsync provides a compact footprint that is 56 percent smaller and 63 percent lighter than common 3-phase induction motors. Power range is .25 to 1.5 hp. They are supplied with swivel connectors and shielded cables to make installation trouble-free. Popular frame sizes available. The product line includes the new motors, quick-connect cables, and a programmable and networked VFD.

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

Real efficiency in logistics automation is achieved when the entire workflow is handled by robotics solutions that communicate smoothly with each other. That's the vision behind ROEQ's new TR500 Top Roller unit that automates load and unload operations of the MiR500, the largest and most powerful autonomous mobile robot from Mobile Industrial Robots (MiR). Danish company ROEQ is launching the Top Roller at the Automate 2019 show in Chicago this week, along with a host of other add-ons for MiR. The TR500 accommodates U.S. pallets and can be delivered with a fully automated lifter functionality for pick-up and delivery of goods.

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.

BMW Group and Jaguar Land Rover announce collaboration for next-gen electrification technology

As it develops its plans for the mobility of the future, the BMW Group is increasingly focusing on partnerships to help make next-level electrification technology more widely available to customers by the start of the coming decade.

Cooperation between car manufacturers to share know-how and resources is important as the automotive industry tackles the significant technological challenges of autonomous driving, connectivity, electrification, and services (ACES).

After three years of a directive called "Strategy NUMBER ONE > NEXT," the BMW Group remains firmly on track, having established a strong position as one of the world's top providers of e-mobility. The company is leading the global premium market with the largest portfolio of electrified vehicles and the biggest market share among traditional luxury rivals.

The BMW Group and Jaguar Land Rover have confirmed they are joining forces to develop next-generation electric drive units in a move that supports the advancement of electrification technologies necessary to transition to an ACES future.

The BMW Group and Jaguar Land Rover share the same strategic vision of environmentally friendly and future-oriented electric drive technologies. The BMW Group brings its long experience of developing and producing several generations of electric drive units in-house since it launched the pioneering BMW i3 in 2013. Jaguar Land Rover has demonstrated its capability through the launch of the Jaguar I-Pace and its plug-in hybrid models.

The BMW Group's most sophisticated electrified technology to date features an electric motor, transmission, and power electronics in one housing. This electric motor does not require rare earths, enabling the BMW Group to reduce its dependence on their availability as it continues to systematically broaden its range of electrified models.

Starting next year, the BMW Group will introduce this electric drive unit, the fifth-generation ("Gen 5") of its eDrive technology, with the BMW iX3 Sports Activity Vehicle. The Gen 5 electric drive unit will be the propulsion system upon which subsequent evolutions launched together with Jaguar Land Rover will be based.

The cooperation allows the BMW Group and Jaguar Land Rover to take advantage of cost efficiencies arising from shared development of future evolutions and production planning costs, as well as economies of scale from joint purchasing.

A joint team of BMW Group and Jaguar Land Rover experts located in Munich will be tasked with further developing the Gen 5 power units. Production of the electric drivetrains will be undertaken by each partner in their own manufacturing facilities. Both companies will seek to adhere to their own brand-specific goals in any project.

The partnership should also help both companies meet regulatory requirements around the world, which often vary by market.
