In order for a motor to accelerate or decelerate a load, it must overcome the load's inertia, or resistance to change in motion, as explained in Newton's First Law. In belt-driven linear motion systems, the motor has to overcome not only the … [Read More...] about How to account for belt and pulley inertia during system design

Linear motion basics: 13 fundamental topics you need to know
Whether you’re new to designing and sizing linear motion systems, or you could just use a refresher, we’ve gathered all the articles that cover mechanical concepts used in linear motion systems and … [Read More...] about Linear motion basics: 13 fundamental topics you need to know
What factors contribute to friction in linear motion systems?
Designers and engineers typically try to avoid or mitigate friction in linear motion systems. Although friction isn't always bad — in some applications, it can provide a damping effect and help … [Read More...] about What factors contribute to friction in linear motion systems?
New sense-and-control actuator model added to Curtiss-Wright Smart Actuator series
Curtiss-Wright’s Actuation Division announced the release of its newest motor/actuators with integral controls, the Exlar SA-R080 rotary and SA-L080 linear actuator. The SA-080 is the first frame size … [Read More...] about New sense-and-control actuator model added to Curtiss-Wright Smart Actuator series
Motion basics: What are degrees of freedom (DOF) and how many are there?
To identify the position of an object in three-dimensional space, we use a coordinate system that defines three axes: X, Y, and Z. If the object is a point mass, we only need three coordinates (X, Y, … [Read More...] about Motion basics: What are degrees of freedom (DOF) and how many are there?
How does hysteresis affect piezo actuator performance?
Piezo actuators operate on the principle that application of an electric field (voltage) induces strain (displacement) in the material — a phenomenon known as the inverse piezoelectric effect. But if … [Read More...] about How does hysteresis affect piezo actuator performance?
Single-axis linear stepper stages with integrated encoder and electronics package
H2W now offers a revolutionary series of single-axis linear stepper stages that integrates a linear encoder into the stage to operate the linear stepper motor as a 2-phase brushless motor when coupled … [Read More...] about Single-axis linear stepper stages with integrated encoder and electronics package

Motion basics: What is ball conformity in linear guides and screws?
In linear guides and ball screws, load-carrying balls or rollers can ride on planar (flat) raceways, as with non-recirculating linear roller bearings, or in curved raceways, as with ball screws and … [Read More...] about Motion basics: What is ball conformity in linear guides and screws?
Magnetostrictive linear position transducers from AutomationDirect
AutomationDirect has added Gefran WPG and WPP series magnetostrictive linear position transducers. These transducers work like other linear position sensors by translating a linear position to an … [Read More...] about Magnetostrictive linear position transducers from AutomationDirect
Motion basics: What is differential slip and how does it affect linear bearings?
Linear bearings that use balls or rollers are typically chosen for their ability to carry high loads with very low friction. But rolling elements — including linear bearings — are not friction-free. … [Read More...] about Motion basics: What is differential slip and how does it affect linear bearings?
