 | Top Product: E-Z LOK threaded inserts and kits for metal
E-Z LOK™ inserts are ideal for repairing or reinforcing threaded holes in soft metals such as aluminum, magnesium, and cast iron. They will not back out or vibrate loose. Their pre-applied, microencapsulated adhesive begins to set immediately upon installation. Despite their firm hold while in use, these threaded inserts can also be removed with heat or a tool. In 2024, E-Z LOK purchased a new LOCTITE® machine to bring insert adhesive application in-house -- a solid improvement for a great product.

 | How do you drive multiple motors with a single VFD?
According to KEB Automation, lots of automation systems use multiple motors to distribute loads, execute different tasks, or to optimize overall efficiency. One control strategy is to use a single variable frequency drive (VFD) for each motor, or you can drive several motors with only one VFD. But when do you use which tactic, and what are the pros and cons of each? Matt Sherman from KEB has got you covered with all the details.

 | New contactless link magnetic couplings use magnetic field to transmit torque
Miki Pulley Magnetic Couplings are shaft couplings that transmit torque from one shaft to another using a magnetic field instead of a physical or mechanical connection. These Magnetic Couplings are non-contact and rely on the attraction and repulsion of magnetic poles to generate rotational power. The full product range can withstand significant misalignments and are silent, vibration-free, and do not generate thermal conduction. Design advantages include configurations that are versatile for use in various engagement angles and installations. Max transmittable torque is adjustable.

 | Frameless BLDC motors for maximum system integration
Nanotec introduces the DKA series of high-performance, frameless BLDC motors designed for compact, efficient drive systems. Featuring a modular design with separate stator and rotor, these motors allow for a maximum level of system integration. Motor diameters from 25 to 115 mm are available with up to 7.8 Nm of torque and speeds to 10,000 rpm. By eliminating the need for couplings or additional mounting components, these frameless motors reduce material usage and assembly costs. Ideal for applications with limited space, including robotics, medical technology, and more.

 | U.S. Marines look deeper into using all-electric seagliders
The U.S. Marine Corps Warfighting Lab has committed $10 million to a second-phase exploratory collaboration with Rhode Island-based REGENT Craft to pursue the development of all-electric seagliders for defense operations. The high-speed, ground-effect craft with retractable hydrofoils can take off and land on water, flying within one wingspan of the surface. It looks so cool and useful, but is it really an aircraft?

| | Videos+: Technologies and inspiration in action | World's smallest pacemaker -- tinier than a grain of rice -- is activated by light
Northwestern University engineers have developed a pacemaker so tiny that it can fit inside the tip of a syringe -- and be non-invasively injected into the body. Although it can work with hearts of all sizes, the pacemaker is particularly well-suited to the tiny, fragile hearts of newborn babies with congenital heart defects. Smaller than a single grain of rice, the pacemaker is paired with a small, soft, flexible, wireless, wearable device that mounts onto a patient's chest to control pacing. When the wearable device detects an irregular heartbeat, it automatically shines a light pulse to activate the pacemaker. These short pulses -- which penetrate through the patient's skin, breastbone, and muscles -- control the pacing. Designed for patients who only need temporary pacing, the pacemaker simply dissolves after it's no longer needed.
