Reliable automated testing of cultured cells in the lab
What dosage achieves the desired result without side effects? Above what limit does the beneficial medication turn toxic? Today, such questions are answered in test series performed with cell cultures. With the CYRIS®FLOX automated test system, work in the laboratories is made much easier. Here, motors from FAULHABER ensure that the cultures are supplied with nutrients and medications for the duration of the trial and the development of the cells is closely monitored -- without human intervention.

Electromechanical linear actuators: High power in small packages
Packing higher motion control capability into a more compact envelope has given rise to a new generation of high power-density actuators. Machine designers for mobile-off-highway, material handling, factory automation, and other power-hungry applications can now get electrical actuators from Thomson that provide up to 2 kN/450 lbf with advanced onboard electronics ̶-- all in a component that requires less space and is more cost efficient than hydraulic or heavier-duty electromechanical actuators that might previously have been deployed for such applications.

New backlash-free threaded nut for external linear actuators
Nanotec now offers radially pre-loaded threaded nuts for its external linear actuators with flange size 42 mm (NEMA 17). These backlash-free nuts automatically readjust themselves during operation and achieve high positioning accuracy and repeatability. Compared to simple, axially pre-loaded nuts, they are characterized by a lower frictional torque and higher efficiency. The nuts are currently offered in combination with the linear actuators of the LSA42 series from Nanotec. These actuators are available in many lengths and thread leads. They come with ACME or trapezoidal thread and facilitate the construction of space-saving linear axes.
A servo motor first: Certified PROFINET with PROFIdrive
Dunker-motoren, a world leader in brushless DC motors with integrated electronics from 1 to 4,000 W, is the first drive technology manufacturer to fully integrate its certified PROFINET solution with PROFIdrive into a motor -- a milestone in terms of cabling, commissioning, and IIoT capability. The certification ensures users that high standards of stability, even under extreme bus conditions, are always maintained. Currently, the products BG 95 dPro, BG 75 dPro, BG 66 dPro, and BGE 5510 dPro are available with the PROFINET interface.
What are piezoelectric active shims?
Active shims, such as PIRest from Physik Instrumente, can readjust the gap between two components in a machine at any time with nanometer precision. Due to the piezo element's high resolution down to the nanometer range, active shims cover applications in classical mechanical precision engineering, as well as the alignment of optical components in astronomy, semiconductor manufacturing, and in materials research employing beam-line instrumentation.

Integrated motor/actuator replaces hydraulics
Curtiss-Wright's Actuation Division has just released its newest integrated motor/actuator,
the Exlar GTX060. This is the third frame size in the GTX series of industrial electromechanical actuators. The GTX Series offers force, precision, and repeatability while eliminating or minimizing the maintenance and inefficiencies typical of fluid power alternatives. With continuous force ratings up to 2,668 N (600 lbf) and speeds to 1,016 mm/sec (40 in./sec) in both VAC and VDC power options, the GTX060's compact form can be applied across a wide range of automation applications.
Critical medical applications demand top-quality motion
Surgical robotics systems offer an overwhelming advantage over traditional methods: improved precision and speed, faster patient healing, and a reduced margin of error.

Voice coil stages and actuators for precise motion
Because of their small dimensions, voice coil motors are often integrated in compact stages, actuators, and fast tip/tilt mirror platforms. These devices are driven by an electromagnetic motor consisting of a moving coil winding and a fixed magnet (the opposite is also possible). By precisely controlling the electric current in the coil, the magnetic force (Lorenz force) -- and thus, acceleration, velocity, and position -- can be varied very accurately.

Mustang Mach-E all-electric SUV takes top spot in Car and Driver's inaugural Electric Vehicle of the Year Award 2021

The 2021 Ford Mustang Mach-E earned Car and Driver's inaugural Electric Vehicle of the Year Award, adding another coveted honor to the car's trophy case and beating overall top-rated EV competitors along the way.
The publication put 11 top-rated electric vehicles through rigorous testing over a three-week period, including a 1,000-mile road trip to evaluate each in real-world conditions. Mustang Mach-E took the No. 1 spot.
"We felt that if a carmaker was looking to convert people from EV skeptics to EV evangelists, there's not a better vehicle out there than the Mustang Mach-E," said Sharon Carty, Car and Driver editor-in-chief. "It's a familiar shape and size of crossover. It's in the sweet spot of what Americans love. It's beautiful. It's a design that gets noticed. It has a range and charging speed that is very competitive."
The newly created electric vehicle award uses the same criteria as Car and Driver's 10Best Awards: The vehicle must deliver exceptional driving engagement, offer indisputable value and/or practicality, fulfill its mission better than any of its competitors, and be fun to drive (which is a great description of Mustang Mach-E).
"Mustang Mach-E is the start of what we can do to compete in the EV revolution," said Darren Palmer, Ford general manager, Battery Electric Vehicles. "Its continued success in the form of happy customers, sales, and awards are all signs of the momentum we are building."
Other contenders included Audi e-tron, Kia Niro, Nissan Leaf Plus, Polestar 2, Porsche Taycan 4S PBP, Tesla Model 3 Performance, Tesla Model S Long Range Plus, Tesla Model Y Performance, Volkswagen ID.4, and Volvo XC40 Recharge. Car and Driver employed instrumented testing, subjective evaluation, and side-by-side comparison in both practicality and entertainment value.
The 2021 Mustang Mach-E has claimed a number of other awards including Car and Driver's Editor's Choice Award earlier this year, plus the Cars.com Eco-Friendly Car of the Year Award, AutoGuide's Utility of the Year, Green Vehicle of the Year, and Autoweek's Car Buyer's Award.
"We could have made a boring electric vehicle, a compliance vehicle that looks like a dust buster," said Palmer, "but we decided people need an EV with soul. So we built them an all-electric Mustang SUV that is disrupting the status quo in electric vehicles -- and the Mustang Mach-E GT and GT Performance Edition are still to come."
The full story on Car and Driver's very first Electric Vehicle of the Year can be found here in the July/August issue of the magazine.
