Watch High-Speed Ultrasonic XY Motor Align!
This mini XY linear stage with piezo-ceramic motors combines sub-micron precision with excellent dynamics -- ideal for optics, medical design and photonics applications. In addition to the high speed up to 200 mm/sec, the low inertia (direct drive, no rotating parts) allows for a rapid start-stop behavior with settling times in the milliseconds. How can you use this XY stage?

Plating: Where to go when you’re going for the (real) gold
When top organizations are thinking about how gold can help enhance a project, they often turn to Laser Gold to solve thermal control problems and enhance performance. Whether it is NASA’s desire for 99 percent infrared reflectivity or the "Academy's" wish to make the finish on the Oscars statuettes more rugged, Epner Technology's Laser Gold electro-plating process is where it’s at.

Wings: Jet-powered UAV tests flapless blown-air control system
When we think of things that fly, they usually have wings with some kind of moving parts. Even Superman had to thrust his arms forward. But engineers at BAE Systems, along with a team of researchers at the University of Manchester in the U.K., have built and flown a jet-powered UAV that is trying out a new type of aircraft control. They call it "flapless flight."

Construction truck design evolves at Hitachi using modern calculation management
The engineering department at Hitachi Construction Truck Manufacturing is taking steps to improve their rigid-frame hauling truck design through improving their design analysis tools. The company has a history of using spreadsheet programs and older coding languages as a means to solve some engineering problems, but these legacy approaches can introduce redundancies and slowdowns in a variety of ways during a design process. Gradually, the department is implementing the use of Maple to maximize the value of its calculation efforts.

Super car brake cooling simulation with CAD-embedded CFD
Brake cooling is a crucial area in motorsport and sports car engineering. A recent thesis project by Arne Lindgren of Halmstad University in Sweden considered different cooling solutions for the extreme conditions of super cars. The project, conducted for super car manufacturer Koenigsegg Automotive AB, had the objective to design an efficient brake cooling solution for their latest model, the Regera. Lindgren used FloEFD simulation software from Mentor Graphics.

Lock your gears, sprockets, pulleys, and more
Posi-Lock bushings from Miki Pulley provide system designers with a keyless option for locking into position gears, pulleys, sprockets, and other components in a mechanical system. These bushings feature socket-head cap screws that tighten quickly and easily, allowing the inner and outer hub of the Posi-Lock to move along shaft contact surfaces. Three different models are available. Applications include machine tools, pumps, molding machines, printing systems, robots, and all types of mechanical systems where hub-to-shaft connections are required.

Mini voice coil motor has high force-to-size ratio
Smaller in diameter than a quarter, the miniature linear voice coil motor (LVCM-019-016-02) from Moticont has a high force-to-size ratio. It produces 8.9 oz. (2.5 N) of continuous force and 28.0 oz. (7.8 N) of peak force in a compact 0.750-in. (19.1-mm) diameter x 0.94-in. (23.8-mm) long envelope (at mid stroke). This high-speed motor has zero cogging and features high accuracy and high repeatability when operated in a closed loop as a DC servo motor. Ideal applications include: pick-and-place; testing; laser steering; mirror positioning; scanning; oscillation; switching; and hand-held medical, dental, or industrial applications.

Development kit for IoT applications
ON Semiconductor is helping engineers address a broader range of high-growth Internet of Things (IoT) applications through the release of a new multi-sensor shield and expansion of software support for its IoT Development Kit (IDK). The IDK gives access to a wide variety of sensing, processing, connectivity, and actuation possibilities through a range of shields/daughter cards that attach to the Arm SoC motherboard. The multi-sensor shield adds a variety of inertial and environmental sensors. These coupled with, for example, the recently announced Bluetooth low energy (BLE) connectivity shield, enable the rapid prototyping of a wide range of ultra-low power smart home, industrial IoT, and wearable solutions.

Gain more torque -- motor has integrated cooling
The slim-design G3718V whisper torque motor from Lin Engineering incorporates a heat-sink design within the stator laminations to allow for passive cooling. When your motor operates cooler, you can increase power to gain more torque without overheating, or you can save energy and still perform at an optimal performance. At only 22.8 mm long, this motor produces 25 oz-in. of torque.
