Optimal Engineering Systems, Inc. (OES) has released four new high resolution, high repeatability XY Alignment Stages. The AU200-120x120 Alignment Stages feature 120 mm (4.724 in.) of travel in both the X and Y axes. These new low profile 87 mm (3.425 in.) high XY stages, have a 188 mm x 188 mm (7.401 in. x 7.401 in.) open aperture. Easy integration of tooling and fixtures is facilitated through a precision series of threaded mounting holes.
The new AT20-600 series of Motorized Vertical Lift Stages from Optimal Engineering Systems, Inc. (OES) features a vertical lift of 600 mm. The AT20-600-01 (pictured) is driven by a Two-Phase Stepper Motor features a repeatability of 5 microns, positional accuracy of 20 microns and has a knob on the motor for manual adjustment.
The following article looks at the latest news on servo motors, drives and motors. How do we differentiate between the definitions? What can design engineers find between a stepper and a servo motor? Also, a quick update this summer on the benefits of closed-loop motor control.
Product design remains the most fascinating aspect of linear motion components as manufacturers try to answer the speed, size and efficiency challenges of customers utilizing rails, tables, actuators, sliders and other components. Companies like Heidenhain, AMTEK, NB Corporation and PBC Linear continue to provide technologies that increase productivity in this rapidly evolving market segment. Credit e-mobility, robotics, motion control and automation technologies for the market growth.
Ametek Haydon Kerk Pittman, a business unit of Ametek, is pleased to announce the availability of its new 43000 Max Series Size 17 single- and double-stack hybrid linear actuators.
The transverse flux permanent magnet motor -- also known as a hybrid step motor or hybrid servo motor -- has a wide range of performances, depending upon how you drive these motors, and whether you operate them in open loop or one of the many variants of closed loop methods you use. In this third installment we will cover some of the many ways to drive these motors, as well as how these choices affect the performance of these motors.
This is the first of a series of articles on permanent magnet transverse magnetic flux motors - AKA step motors. These articles will be covering the development history and the various drive technologies used with these motors - both open and closed loop.
