Hybrid steppers and other stepmotors in linear actuators

★ By Lisa Eitel Leave a Comment

Stepper motors are commonly used in linear motion applications for their precise positioning capabilities and good holding torque. Though the basic operating principle is the same for all stepper motors, there are differences in operation and performance between the three primary types — permanent magnet, variable reluctance, and hybrid. Permanent magnet stepper motors Permanent magnet […]

Leadscrews in medical equipment

★ By Lisa Eitel Leave a Comment

Leadscrews are essential to surgical robotics, patient-monitoring systems, diagnostic imaging devices, and rehabilitation equipment. By Chris Nook | Chairman and CEO • Helix Linear Leadscrews are those spiral shafts that (upon application of torque) convert rotational motion into linear motion — axially advancing and receding a mating nut to deliver accurate positioning. They’re well suited […]

What is a high helix (high lead) screw?

★ By Danielle Collins Leave a Comment

Ball and lead screws are specified by the diameter of the screw shaft and the lead (or, in some cases, pitch) of the screw thread. The lead, which specifies how far the nut travels for each revolution of the screw, is created by the thread, or helix, that wraps around the screw shaft. If the […]

Screw drives see new uses in robotics, other applications

★ By Miles Budimir Leave a Comment

ball screws

Some of the surest, time-tested methods of linear actuation are screw drives. Whether lead- or ball- or roller screws, screw actuation remains a large part of the linear actuation equation, thanks to their reliability, accuracy, and relative simplicity of operation. Recently screw drive developments have included advances in materials as well as manufacturing methods leading […]

Part 2 of 2: Electric actuators as an alternative to hydraulic cylinders

★ By Lisa Eitel Leave a Comment

Here we offer some tips for converting a fluid-power-driven axis to electrical actuation. By Ryan Klemetson • Business Development Manager | Tolomatic, Inc. As explained in Part 1 of this article series on motioncontroltips.com, hydraulic systems offer long service life, but they’re not as efficient as electric systems. Electric systems also provide precise position, velocity, […]
