Vacuum Compatibility and Why It Matters Vacuum applications present a unique set of challenges for electromagnetic actuation. Brushless DC motors, whether rotary or linear, are composed of materials and built by processes that do not readily make them vacuum compatible. When considering a motion system requiring vacuum, partnering with a trusted motor/motion system supplier, with…

Aligning Magnet Track Segments This blog provides instructions for the proper spacing and alignment of multiple magnet track segments with even numbers of magnet pairs. Contact our Solutions Center for guidance in aligning tracks with odd numbers of magnet pairs or if tracks with even and odd magnet pairs are combined. Background Allient linear motors…

What is a Torque Motor? LS Series Torque Motor Torque motor is a term that has been created to describe a motor that will be used mainly for torque control in a precision system. Many of these systems move in very small increments and limited angles of rotation and the motor could be holding position…

Direct Drive – An Engineer’s Guide Direct Drive has seen a rebirth in awareness and new applications over the past 20 years. Driving a shaft directly is really nothing new and has been done for over 100 years. What has changed is the types of motors used for the application and the types of motor…

Why Sensor Resolution Matters More Than You Think in Vibration Control In high-precision motion control systems like those used in semiconductor lithography, optical inspection, or precision manufacturing, the terms “sensor resolution” and “servo bandwidth” are often tossed around interchangeably, sometimes even confused as being functionally synonymous. But they’re not. And understanding the difference between the…

Precision On Your Terms – The Case for Customer-Driven Motion Solutions A Case Study of Customer Driven Precision By Mark D. Holcomb, Director of Product Management In precision motion control, the industry has often fallen into a familiar trap, assuming that more precision is always the answer. Nanometer-level accuracy? Great — but not every application needs it.…

Driving Innovation in Digital Pathology with Precision Motion Control Systems The world of pathology is undergoing a seismic shift. Traditionally, pathologists have relied on physical glass slides, manually inspecting tissue samples under a microscope — a process that is time-intensive, highly specialized, and geographically limited. However, digital pathology is changing the game. By digitizing tissue…

Allient’s Guide to Motor Technologies and Architectures Motor Terminology Cogging Torque Cogging torque is a torque disturbance related to the change magnetic circuit reluctance with angle. It is caused by the non-uniform lamination tooth structure. It is customary to skew stator laminations or magnets to minimize the effects of cogging, but it is difficult to…
