Gantry robots, X-Y tables, split bridges, and stages all serve specific functions. There are many ways to build linear systems for motion in the X, Y, and/or Z directions — also called Cartesian coordinates. Industry terms for these systems depend on how the axes are assembled, where the load is positioned, and (to some extent) […]
Hybrid steppers and other stepmotors in linear actuators
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 […]
Maximizing cobot ROI through seventh-axis-enabled collaboration
Robot transfer units have become increasingly important to automated settings. Now, transfer units with collision detection pair with collaborative robots for human-centric technology enabling previously unimagined levels of productivity. Kyle Thompson • product innovation manager | Thomson Industries Chris Diak • southeast automation manager | Motion Most robot arms have six axes of motion, fewer […]
Omega Drive technology outputs linear or rotational motion
RUD’s new Omega Drive is a new chain drive with a 180° wrap angle. From the Tecdos series, it is suitable for both linear and rotational motion — capable of rotating, lifting, and lowering loads in various on and offshore settings. Applications include shifting harbor and ship cranes, relocating machinery, and solar panel sun tracking. […]
Linear positioning stage includes absolute encoder and frictionless motor
Global precision motion control and nanopositioning supplier Physik Instrumente (PI) now sells a high-dynamics linear motor stage family — the V-574, a new series of linear positioning stages with guiding precision and frictionless three-phase linear motors. Equipped with high-precision crossed-roller bearings installed in a proprietary process, these stages achieve excellent geometric performance. The 130mm variant, […]
Increased speed with new planetary screw assembly
New intermediate size of the proven planetary screw assembly from Bosch Rexroth achieves double the linear travel speed and cycle time at the same rotary speed New intermediate size 48×20 for high-power applications Higher transmission ratio shortens cycle times and increases productivity Quick product selection and online configuration using e-tools The ongoing trend towards electrification […]
Leadscrews in medical equipment
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 […]
PBC Linear MTB series now includes MTB 105 belt-driven actuator
PBC Linear, a Pacific Bearing Company and a global leader in linear motion solutions, is pleased to announce it has expanded its MTB Series of Belt Driven Linear Actuators line with the MTB 105. Engineered with precision and versatility in mind, the MTB 105 is specifically designed to integrate into multi-axis medium- to large-sized Cartesian […]
Bosch Rexroth adds linear motor modules to its portfolio
Fast, compact and precise — these properties characterize the new linear motor modules (LMM) from Bosch Rexroth. The axes come in sizes 140, 180 and 220 mm and feature a zero-backlash direct drive. They complement the existing linear motion technology portfolio as a ready-to-install solution offering excellent value for money. The linear motor modules come […]
Integrated linear-motion variations becoming the norm
Automation over the last several years has expanded use of electric linear actuators to leverage their technological advancements in smart homes, aerospace, defense, and industrial applications. In fact, the global linear actuator market could (in large part because of electric options) surpass U.S. $52.67B this year and grow at a compound annual growth rate through […]
