Voice coil actuator basics
Voice coil actuators are a type of direct drive mechanism that provides extremely precise positioning over small displacements. Like linear motors, they work on the principle of a permanent magnet field and a coil winding. When a current is applied to the coil, a force is generated. This force, known as the Lorentz force, is […]
How to calculate velocity from triangular and trapezoidal move profiles
When designing and sizing a linear motion system, one of the first steps is to determine what type of move profile the application requires, since this determines how to calculate velocity and acceleration, and has a significant effect on their average and maximum values. Velocity and acceleration are two fundamental aspects of any linear motion […]
A summer tribute to linear motion
Amusement parks are a staple of summer vacation, with over 375 million attendees annually in North America alone, according to the International Association of Amusement Parks and Attractions. (Worldwide annual attendance figures are around one billion!). And for many of us, the appeal of amusement parks can be summed up in two words: roller coasters. […]

New voice coil actuator delivers low hysteresis/low friction
For some applications, inconsistent motion caused by excessive friction is simply not an option. BEI Kimco has developed a new Linear Voice Coil Actuator (VCA) that provides extremely low hysteresis/low friction with precise and consistent bi-directional position control. Initially designed to meet the exacting requirements of an anesthesia machine, the new LAH15-19-000A VCA will serve […]
How to size and use stepper motors that integrate rotary-to-linear motion?
No motor subtype satisfies all applications, as all have their own benefits and drawbacks. Even so, axes that need incremental strokes often use dc motors that are either stepper or servomotors. Very advanced designs incorporate linear motors to do away with gearboxes, belts and pulleys, ballscrews, leadscrews, and other power-transmission components — for high accuracy […]
Thomson Increases Design Flexibility for Machine Engineers
Thomson Industries, Inc. has built upon its selection of miniature metric precision ball screws to include three common interface styles: flanged, threaded and rounded. This comprehensive offering equips customers with even more options when designing small-space applications. These metric ball screws deliver a host of performance, supply chain and pricing benefits for users seeking smooth, […]
Gaining a measurement edge with linear encoders
Edited by Miles Budimir || Encoders help linear motion stages reach higher levels of accuracy and performance. Application demands of modern motion systems are pushing the envelope for greater accuracy and finer resolution. Case in point; laboratory equipment with demands for high accuracy positioning of test samples, such as in microscopes. When it comes to […]
