Exceptionally high speed and dynamics
With its speed and torque, the new AM3248 stepper motor from FAULHABER raises the bar in terms of performance and dimensions. Offering up to 10,000 rpm, it can achieve five times the speed of comparable stepper motors. Combined with a gearhead reduction of 100:1, it supplies a torque of 5 Nm. The motor delivers these values with a diameter of just 32 mm and is ideally suited for a wide range of applications including aerospace, lab automation, large optical systems, the semiconductor industry, robotics, and 3D printing.

Alloy claimed to be better for soldering ADAS systems -- may help OEMS reduce risk of recalls
A global automotive materials company has demonstrated the reliability benefits of a unique alloy that it says can replace traditional tin/silver/copper (SAC) alloys in the design of Advanced Driver Assistance Systems (ADAS). Internal tests suggest the alloy can play a significant role in helping automotive OEMs eliminate the risk of solder fractures -- a potential cause of failure in ADAS hardware.

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.

Strain sensor can help prevent structural disasters
Developed to help prevent civil disasters and save lives, HEIDENHAIN's ESR digital strain sensor monitors the structural health of bridges, buildings, wind turbines, and even automation equipment. This fatigue-free measurement concept provides high-resolution digital input into a system of choice. With a renewed emphasis on improving the national infrastructure, the digital ESR strain sensor is the perfect option, since it offers significantly higher accuracy and increased robustness when compared to conventional strain and vibration gauges. It also offers transferable mounting, allowing users to move the one-gauge sensor to multiple locations.

Optimize large mechanical misalignments, get hidden benefits
C-Flex Couplings combine the best qualities of disc, beam, and bellows couplings in a unique and economical design. Made to couple two rotating shafts together, these couplings can accommodate large misalignments while transmitting high torque loads with zero backlash. Benefits include lower energy usage and less-frequent bearing failure, since less stress is placed upon bearings. Constructed using high-strength hardened stainless steel or glass impregnated polyamide flexures, these couplings require no maintenance and provide years of trouble-free life, even in contaminated environments. Flexible Pivot Bearings and Super Plastic Torsional Damping Couplings also available.
See C-Flex Couplings handle misalignments.
