|Designing with Piezo Transducers -- from Welding to Medical
Piezo transducers can provide high-frequency sound waves; they can also be operated as sensors and energy harvesters. Piezo actuators and motors provide highly accurate motion in a small package. A variety of sizes, shapes, and materials is available to best match the individual application.
|Universal Robots to host Expo on Metal Fabrication Applications
Whether you're designing applications for welding, cutting, grinding, polishing, or machine tending, you already know the bad news: rampant skilled labor shortages exist across the nation. Collaborative automation is quickly emerging as a solution -- but where to start? Universal Robots' two-day Expo focused on Metal Fabrication, April 13-14, 10AM-5PM EST, is a vibrant virtual experience with live demos, interactive keynotes and booths featuring a wide range of cobot-powered applications.

|What motor torque constant to use for drive type: Theory and application
Calculating motor torque from available drive current can be confusing due to many different drive types and the multiple ways current is specified. This informative online paper from Celera Motion provides the key formulas for torque constant and motor current from the fundamental principles of three-phase motor theory. It also walks through the many ways torque can be calculated. This information applies to a brushless motor (BLAC or permanent magnet synchronous machines) configuration.

|MathWorks releases MATLAB and Simulink 2021a
Release 2021a offers hundreds of new and updated features and functions in MATLAB and Simulink, along with three new products and 12 major updates. New capabilities in MATLAB include dynamic controls in live scripts as well as a new task for adding plots to live scripts without writing any code. Simulink updates enable users to import C code as reusable Simulink libraries and to speed up simulations. R2021a also introduces new products in the areas of satellite communications, radar, and DDS applications.
|New skinny enclosure air conditioners
Seifert Systems has introduced the SoliTherm SlimLine Series of enclosure air conditioners that have an inside-cabinet depth of only 3.5 in. and are 4.5-in. deep overall. The SlimLine Series has a condenser specifically designed to maintain performance without maintenance -- even in environments where dust and dirt are present. Models are available with steel covers and external or recessed mounting. The line provides cooling capacities from 1,130 to 5,120 BTU/hr. Operating temperature range is 50 F to 122 F or 131 F -- depending on model. Eight SlimLine models available.
|Easy-integration compact Z-Theta motion platform
The easily integrated Z-Theta motion platform from Haydon Kerk Pittman offers linear and rotary point-to-point motion in a compact footprint. This modular, "bolt-in" package features the patented ScrewRail linear actuator, which combines guidance and linear transmission in a slender co-axial profile. The unique dual-motion integration with a pair of stepper motors adds rotary (theta) motion that reduces motion system size by 50% to 80% and provides as much as a 60% overall cost reduction when compared to traditional design approaches. This setup can be customized with a variety of lead screw resolutions, free-wheeling and anti-backlash nuts, stepper motor options, and optical encoder line counts.
|Good beer. Zero packaging accidents.
The Danish division of Carlsberg, one of the leading brewery groups in the world, has significantly improved staff safety and taken steps toward achieving zero accidents since integrating Universal Robots cobots into its Fredericia-based factory. The company invested in two cobots, the space-friendly UR3 and the powerful UR10, to tackle carrying packaging cartons from the pallet to the magazine -- a monotonous and strenuous task that often left staff with repetitive strain or severe cuts. Working in tandem, the cobots can handle up to 500 packaging cartons per hour. Now the company has purchased four additional cobots to further automate its production lines.

|Toughened NASA low-outgassing epoxy
Master Bond Supreme 70CN is a two-part epoxy adhesive formulated using a natural, renewable, and sustainable ingredient. This moderate-viscosity, unfilled epoxy is black in color and can be used for bonding, sealing, coating, and potting in aerospace, electric vehicle, electronic, opto-electronic, battery, and OEM applications, particularly those involving composites and fibers. It resists thermal cycling and is ideal for bonding dissimilar substrates including metals, ceramics, many rubbers, plastic materials, and composites. It features low shrinkage upon cure, a high tensile strength, is serviceable from -100 to 400 F, and has a working life of 60 to 90 min.

|All-new Ford Raptor 2021: Grown up but still a rebel
The Ford Raptor line hit the scene in 2009 as the ultimate off-road pickup. Like a rebellious, brawny teenager, the high-performance F-150 was brash, fearless, and unapologetic -- ready to jump and to catch some air. Sitting on 37-in. tires, the all-new 2021 third-gen F-150 Raptor is stronger and can take more licks with its updated suspension, but it's smarter and more sophisticated too.

|Honey, I shrunk the V-8 engine!
Piezo V-8 Linear Motor: Borrowing from the classic design of a V-8 engine to achieve high push/pull and holding forces, patented piezo actuator technology and linear stepping motion design principles come together to create the fastest and strongest non-magnetic drive of its class size. These piezoelectric motors are self-clamping, i.e., at rest or in steady-state mode, they automatically hold the position without any need for power. Learn how this technology can be used in your application.
