What are common applications for hybrid stepper motor linear actuators?

November 15, 2021 By Danielle Collins Leave a Comment

When it comes to electromechanical linear actuators, integrated designs offer space savings, reduced complexity, and lower total cost of ownership with fewer parts required for repair or replacement. One such design that’s found multiple uses in medical, 3D printing, and assembly applications is the hybrid stepper motor linear actuator, which combines a ball or lead […]

How axial and radial loads affect linear motion systems

November 10, 2021 By Danielle Collins Leave a Comment

axial radial loads

In any motion system, understanding the type and direction of applied and resultant loads is important for determining bearing life and analyzing deflection. In linear motion systems, we typically use Cartesian coordinates (X, Y, and Z) to define the placement and direction of loads. But for rotating components such as screws, rack and pinion drives, […]

Piezo motors vs. voice coil actuators for micron and sub-micron positioning

November 4, 2021 By Danielle Collins Leave a Comment

piezo motors

Applications that require micron or sub-micron level positioning with extremely smooth motion and control often call for a direct drive system — linear motor, piezo motor, or voice coil actuator. Linear motor stages are typically used when high forces are needed over stroke lengths greater than a few hundred millimeters. But for high-precision applications with […]

How to account for rack and pinion inertia during system design

October 21, 2021 By Danielle Collins Leave a Comment

Rack and pinion systems

Rack and pinion drives are often used in applications that require stroke lengths beyond the practical limits of ball screws and thrust forces that exceed the capabilities of belt drives. And in some applications, rack and pinion systems can also provide lower total inertia than a suitable ball screw or belt drive alternative, which can […]

What factors contribute to friction in linear motion systems?

October 13, 2021 By Danielle Collins Leave a Comment

bearing friction

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 improve servo tuning — when it comes to linear motion systems, it increases the amount of force required to move a load, creates heat, […]
