New linear rotary actuator features 35-mm stroke with 5-micron encoder
The LCR16 from SMAC Moving Coil Actuators provides precision Z-theta motion within one small actuator, which is suitable for pick, orient and place applications. A wide variety of LCR16 linear rotary … [Read More...]
How does closed-loop stepper control work? (And why not just use a servo?)
Stepper motors are inherently open-loop devices. They don’t require feedback because each pulse of current delivered by the drive equals one step of the motor (or a fraction of a step, in the case of … [Read More...]
One-piece ETX linear bearing/pillow blocks suitable for use in radioactive environments
LM76 now offers one piece ETX Linear Bearing/Pillow Blocks that will not degrade in a radioactive environment. Machined from a solid block of self-lubricating ETX, linear bearing blocks have high … [Read More...]
What is Abbé error and how does it affect linear systems?
When evaluating the accuracy of a linear motion system, the area of focus is often the positioning accuracy and repeatability of the drive mechanism. But there are many factors that contribute to the … [Read More...]
Follow these four tips when using L10 life to size linear bearings
The well-known bearing life equation, often referred to as L10 life, is a fundamental element in the sizing and selection of recirculating linear bearings. Through statistical analysis and real-world … [Read More...]
New piezo driver with 1,200 W of power for fast switching applications
PI (Physik Instrumente) has released the new model E-619, a high-power piezo amplifier designed to drive high-capacitance multilayer piezo actuators with rapid rise times or high frequencies. As a … [Read More...]
HEIDENHAIN’s new LC 201 single-section linear encoder for absolute applications
Long machine tool axes are increasingly being equipped with linear drives, and HEIDENHAIN’s new LC 201 absolute linear scale was introduced to specifically meet those drive position feedback needs. … [Read More...]
What’s the difference between backlash and hysteresis in linear systems?
In linear systems, backlash and hysteresis are often referred to as the same phenomenon. But while they both contribute to lost motion, their causes and methods of operation are … [Read More...]
Moving coil technology: Benefits today (and innovations on horizon)
Moving coils have been around for many years. Now though, market pressures are causing the technology to rapidly evolve and gain in use. This technology competes most directly against pneumatic drives … [Read More...]
