When are voice coil actuators the best linear motion option?
Voice coil actuators are most commonly used for micro- or nano-positioning applications, with strokes from 10 nm up to 100 mm. In addition to very precise positioning capabilities, voice coil actuators provide extremely smooth movement. They’re often paired with air bearings, crossed-roller guides, or linear shafts and round bearings to provide assemblies that are backlash-free. […]
What does RMS stand for, and how does it apply to linear systems?
Let’s answer the first question: What does RMS stand for? RMS, or root mean square, is a statistical term that is used for determining the mean (or average) of a set of values. It’s especially useful when the values vary as a function of time. The technical definition of root mean square is the square […]
On location: Parker Hannifin manufacturing and design services — future of integration
Recently I made a day trip from Cleveland to the Pittsburgh area for a facilities tour with a leading motion-component supplier. The Parker Hannifin Electromechanical and Drives Division offers engineering expertise as part of their industry support — and designs and produces motion-control systems to meet myriad application requirements. These range from miniature stages for […]
Intelligrated automated palletizing for citrus packer a Top Supply Chain Project for 2017
Intelligrated — a North American-based automated material-handling provider — was recently listed on Supply & Demand Chain Executive’s 100 great supply chain projects for its Bee Sweet Citrus design work. Bee Sweet Citrus is an independent packer and shipper of California citrus to serve a market that stretches from Europe to Australia. Faced with rising […]
What is Torque?
In this article, we answer the common question “what is torque?” Although torque refers to rotational motion, it is a fundamental concept in linear motion applications. Rotary motors produce torque, and when this torque is transmitted to a drive system – such as a screw, belt and pulley, rack and pinion, or chain and sprocket […]
Two new absolute linear encoders with several interface options from NUMERIK JENA
NUMERIK JENA now offers two families of absolute linear encoders to fit into tight spaces. Called the LAK and KIT LA, these non-contact encoders offer several types of electrical interfaces, including EnDat 2.2 with analog signals. This interface allows motion stage manufacturers to use the absolute position values and the analog position values for different […]
Vertical linear motion: Hoists to lifts to AS/RS reach new heights
New technologies boost the reliability and efficiency of vertical motion designs (including an array of lifts and hoists) for setups of various sizes. In the feature, we get input from one industry expert on the subject and then outline five key parameters that dictate what makes linear actuators suitable for lifting. Mounting orientation — especially […]
How to calculate acceleration
Once you know which move profile is being used, you’ll need to know how to calculate acceleration based on total move distance and total move time. When sizing a linear system, a lot of attention is given to velocity, but the effects of acceleration on the system and its components are often more significant than […]
SKF CAHB-E series electromechanical linear actuators — Drop-in alternatives to hydraulics
New SKF CAHB-E series electromechanical linear actuators introduce powerful, efficient, and environmentally friendly drop-in alternatives to hydraulic systems, whether for OEM or aftermarket system applications. These next-generation actuators are engineered to deliver increased thrust and holding force compared with previous designs and to achieve enhanced levels of speed, precision, and reliability. They ultimately can perform […]
