Tech Tip: How to keep heavy loads balanced

Some Thomson smart linear actuators have a position-based synchro-nization option to help manage unbalanced loads when using multiple units. The system adjusts the speed of each actuator to keep them starting, moving, and stopping synchronously, regardless of their respective load distribution. So useful. So smart.

Micro-brakes for precise motion control applications

The ultra-compact 112 Model Electro-magnetic Micro-Brakes from Miki Pulley ensure fast response in high-torque, demanding applications. The simple design features a stator with integrated mounting flange, proprietary composite friction liner, and armature complete with ring plate spring and hub. These brakes halt rotation mechanically by utilizing an electromagnetic field to create mechanical friction. With fast response, the brake's armature engages the stator when the coil is energized. A constant-force plate spring transfers torque to the rotating brake body, halting all motion.

What is a low-waving linear motion guide?

If you are having a problem with your linear guides not always staying perfectly straight during use, it may be due to a phenomenon called waving -- a problem that is particularly critical in high-precision markets such as semiconductor and LCD equipment-related applications or machine tools. Thankfully, THK has an answer.

Bodine Electric gearmotors have higher torque ratings

Bodine Electric Company recently upgraded the design of many of its type WX gearmotors to increase the output torque ratings while maintaining the same long-life rating. Two parts in the gearhead design were changed to accomplish the higher torque ratings: the rotor/armature shaft and the first-stage gear. This design change allowed Bodine to raise the output torque rating for any WX gear ratio where the first stage of the gearing cluster had been the "weak link." This included all of the two-stage ratios used in Bodine stock models and two of the three-stage ratios used in Bodine stock models.
Find out all the new capabilities and models in this Bodine blog.

Pick and Hold solenoid driver module designed for economy, extended life

Magnetic Sensor Systems (MSS) has released the Pick and Hold SDM950 Power Solenoid Driver Module. This "Made in America," compact, PWM driver module measuring just 2.950 x 3.000 in. is designed to consume less energy by first applying the voltage for a pre-determined period of time (pick time) necessary to activate the solenoid and then, when the plunger is seated, drop the voltage (holding voltage) to a level sufficient to hold the solenoid in the seated position. This conserves energy and extends the life of the solenoid.

High-precision micro-positioning actuators

For applications requiring sub-micrometer precision, PI's L-220 series linear actuators provide reliable, high-precision motion in a compact design. Engineered for demanding tasks in optics, photonics, semiconductor testing, metrology, and microscopy, select models are available with short lead times to support fast system integration. Their low backlash and non-rotating, linearly guided tips minimize tilt and eccentricity-caused errors, as is common with low-cost, rotating-tip type actuators.

How to convert from hydraulic cylinders to electric actuators and why

Hydraulic cylinders are traditionally the go-to technology for high-force linear motion. They deliver high force at a low cost-per-unit of force, are rugged, and are simple to deploy. However, electric cylinders with high-force capacities are now available, and they are more flexible, precise, and reliable than their hydraulic counterparts. This is a very detailed article, including lifecycle and power costs, force requirements, and data collection.

Latest iRobot Seaglider unmanned underwater vehicle allows for increased payload capabilities

iRobot Corp.'s Seaglider unmanned underwater vehicle (UUV) can now be outfitted with a larger set of fairings, which significantly increases the UUV's volume and mass payload capabilities. Payload mass is doubled over Seaglider's original design to 4 kg, and payload volume has expanded 650% to more than 21,000 cubic cm, resulting in the ability to integrate both larger sensors and a greater number of sensors within Seaglider.

A long-range, high-endurance UUV, Seaglider operates at water depths between 20 m (approximately 65 ft) and 1,000 m (3,280 ft). This is the first UUV to complete a mission lasting longer than nine months without needing to replace its battery, and the first to complete a mission of more than 3,800 km (approximately 2,360 miles).
