New 22mm Brushless Servo Motor Packs a Punch MICROMO launches the brand new FAULHABER 2264 BP4 series brushless dc servo motor. At 22 mm in diameter, 64 mm in length and weighing only 140 grams, the 2264 BP4 series delivers 59 mNm of continuous torque, and reaches speeds up to 34,500 revolutions per minute. This impressive power and performance capability is possible due to a new segmented winding of the coil, which also improves overall efficiency of the motor. Learn more. This motor has lots of applications.

World's largest jet engine takes maiden flight The world's largest jet engine took its first flight over the Mojave Desert on March 13. The GE9X is a showstopper. At 134 in., its fan diameter is so tall and wide that Shaquille O'Neil would fit inside the engine's cover with Kobe Bryant sitting on his shoulders. The whole engine is as wide as the body of an entire Boeing 737. By Tomas Kellner, GE Reports.

0.38 sec: Fastest Rubik's Cube-solving robot uses 6 Kollmorgen ServoDisc motors A pair of enterprising engineering students has posted a video online that shows a machine they built solving a Rubik's Cube puzzle in 0.38 sec -- the fastest in the world by far if they can get it made official (current world record is 0.637 sec). The machine was created by MIT Biometrics Lab Master's student Ben Katz and software developer Jared Di Carlo, and each has posted an in-depth blog about their creation and methods. "We noticed that all of the fast Rubik's Cube solvers were using stepper motors and thought that we could do better if we used better motors. So we did," said Di Carlo, adding that each motor "can accelerate insanely fast. In a 10-ms quarter-turn move, the motor reaches over 1,000 rpm." Katz said the device uses six Kollmorgen ServoDisc U9-series motors. "Two were taken from my old robot arm project, the rest were found pretty cheaply on eBay," he said. Two PlayStation cameras are also part of the mix. Read Katz's blog, which contains videos and a link to his partner's page.

Ford chases a retro spirit with 50th anniversary Mustang Bullitt Ford has a special-edition model due out this summer -- the all-new Mustang Bullitt, which celebrates the 50th anniversary of the movie "Bullitt" and the car in its iconic 10-minute San Francisco chase scene with Steve McQueen as the driver. While the 2019 475-hp model is cool, the story behind the original movie car and how it resurfaced is just as interesting.

Top Tech Tip: Choosing between brush and brushless DC motors: What are the tradeoffs? Designing a system that involves motion and performs as intended requires choosing the right motor. The most fundamental decision involves commutation type. In some cases, mechanically commutated brush motors provide the best solution for the budget. In other cases, only brushless DC (BLDC) motors will do. Allied Motion provides a comprehensive review of the technology, along with tips and tricks for choosing the right solution for a given application. Read the whitepaper (no registration required).

Top Tech Tip: Overcoming motor inertia -- 5 things you need to know Most engineers recognize that gearheads can be used to create a better inertia match between the object that is being moved and the motor being driven. Put simply, it is dictated by the gearhead ratio where the object reflected inertia to the motor is reduced by 1/ratio2. So, what should the correct inertia be? Jeff Nazzaro, gearhead and motor product manager, Electromechanical and Drives Division, Parker Hannifin, runs through what you need to know about gearhead and servo motors. Read this informative Parker Hannifin blog post.

Top Tech Tip: Benefits of hybrid bearings Hybrid bearings have shown good performance in poor lubrication and contaminated conditions, but the understanding of the contributing mechanisms and their effect on performance is still lacking. SKF has developed more insight into the tribology of hybrid bearings through both dedicated experiments and modeling.

Top Product: Alternative to traditional drive systems Nexen Group has introduced a stainless steel version of its patented precision roller pinion system (RPS). The Nexen RPS engages two teeth simultaneously to achieve superior accuracy with zero backlash at any length. The system is also extremely quiet and 99% efficient. Stainless steel makes the system corrosion resistant, with a long life of up to 36 million meters. Nexen's RPS provides a low-maintenance, durable alternative to rack and pinion, ball screw, and belt drive technology. The RPS is used for a wide range of applications including laser cutting, plasma cutting, and gantry applications.
