As engineers expand their range of machines to a point where a larger payload is required, an upgrade of their linear motors may be necessary. So, to make their design process easier, ETEL has added extra ironcore linear motor lengths to each of their different widths. These new lengths are compatible with existing 50, 70, […]
Where linear motors improve designs: Application example in multi-axis stage
Machine-tool applications and the manufacture and assembly of semiconductor components account for more than half of all linear-motor use. That’s because linear motors are precise (albeit costly compared to other linear-motion options). Other applications for these relatively new motion components also include those that need fast and precise positioning or slow and extremely steady strokes. […]
ELP electric linear module from SCHUNK for user-friendly operation
The SCHUNK ELP can be adjusted in two simple steps making it the most user friendly electric linear module on the market. The end positions can be mechanically adjusted with a screw and the speed of extension and retraction is adjusted using rotary switches on the side of the unit. More after the jump. Speed […]
New linear motor stages with magnetic direct drives and motion controller
Ultra-precise linear motor stages are well-suited for industry and research positioning and scanning applications, such as found in precision automation, micro-assembly, biotechnology, laser beam control, optics, lens testing, and photonics alignment. Motion and nanopositioning industry leader PI is expanding its PIMag® series of high dynamics linear motor stages with 2 new models and a new […]
The top 5.5 linear motion stories of 2016
As a writer and editor, it’s always fun (and sometimes surprising) to look back at the end of the year and see what articles our readers were most interested in. And for you, our readers, it offers the chance to take a quick look at what are, at least to some of your peers, important topics […]
How linear force-current relationships from linear motors improve motion
Applying an electric motor is easier when one knows what it will output for a given input. The simpler it is to predict that, the more elegant and robust the design. To this end, some linear motors have linear force-current relationships so engineers don’t need to accommodate nonlinear effects through approximation or additional terms in […]
How to shrink the size of a linear actuator
Linear actuators come in a wide range of sizes, and over the past several yeas, manufacturers have been emphasizing more and more compact footprints. But no matter how small the actuator, the addition of a motor can make the overall size of the complete system too large for space-constrained applications. Some manufacturers are addressing this issue […]
Can stack linear actuator provides exceptional performance
Portescap introduces the next generation of high power density Can Stack Linear Actuators, the 20DBM. These 20 mm linear stepper motors offer an optimized design ideal for applications demanding high linear force. The new 20DBM features an optimized magnetic circuit which provides improved performance over existing designs The 7.5 degree step angle provides finer incremental […]
Linear systems for nanopositioning
When we talk about linear motion, we typically discuss applications where the travel distance is at least a few hundred millimeters, and the required positioning is in the range of a few tenths of a millimeter. And for these requirements, guides and drives with recirculating bearings are a good fit. Case in point: the lead […]
Linear motion calculator android app from H2W Technologies
To help customers understand their motion requirements and translate them into acceleration and force values, H2W Technologies has developed an Android application that solves linear motion calculations with a range of velocity profiles. This helps the user understand which product might work best for their particular application. The motion profiles available in the calculator include […]
