PI (Physik Instrumente) has released the new model E-619, a high-power piezo amplifier designed to drive high-capacitance multilayer piezo actuators with rapid rise times or high frequencies. As a special form of electro-ceramics, piezo materials are the gold standard when it comes to speed, force, and precision in a small package. Providing sink/source currents up […]
HEIDENHAIN’s new LC 201 single-section linear encoder for absolute applications
Long machine tool axes are increasingly being equipped with linear drives, and HEIDENHAIN’s new LC 201 absolute linear scale was introduced to specifically meet those drive position feedback needs. This new scale is a single-section METALLUR tape encoder that’s ideal for use in linear motor applications that may be required to reach high acceleration levels […]
Dunkermotoren launches compact linear motor with double peak force
With the SA/SC 38 series, Dunkermotoren presents a new modular concept for tubular linear direct drives. The highly dynamic three-phase linear motors deliver up to 3,690 N and accelerate at over 200 m/sec2. The modular design is currently available as actuator version SA (with maintenance-free plain bearing system) and component version SC (for modules). If […]
What are some considerations for linear actuators in contaminated environments?
Reliable motion is often difficult to obtain when the operating environment is heavily contaminated with debris, or contains extreme conditions such as a wide temperature range or other environmental factors.The use of machinery for operations such as cutting, welding, and material processing often generates a substantial amount of debris contamination. Equipment that is not designed […]
The top 5 articles on Linear Motion Tips for 2018
It’s the end of another calendar year here at linearmotiontips.com and what better time than now to do a bit of reflection. It’s an opportunity to do a reckoning of sorts and find out what you, our readers, liked most. So here is a short list of the top 5 most viewed posts published in […]
Low-profile XY open-aperture stage features 1 micron resolution, 2 micron repeatability
OES (Optimal-Engineering Systems, Inc.) has added a new, high-precision open aperture stage to its expanding line of precision XY stages. The AU200-100×100 stage is a low profile stage measuring just 80 mm (3.150 in.) high with a compact footprint (including the motors) of 348 mm x 348 mm (13.701 in. x 13.701 in.) The linear […]
Motorized linear X-axis plus rotary positioning stages from OES
Optimal Engineering Systems, Inc. (OES) has released a new series of high precision X-axis stages with integral rotary positioning stages. The four X-and-theta stages in this series feature linear travels of: 15 mm (0.591 in.), 30 mm (1.181 in.), 50 mm (1.968 in.) and 75 mm (2.953 in.). The rotary table is capable of continuous […]
ANCA Motion expands high-performance tubular linear motor line
The LinX M-series linear motor features an integrated position sensor with 10 um of resolution, eliminating the need for an external encoder, simplifying system design and reducing overall cost. Modular design of the heatsink and end-caps enables flexibility in system integration. The motor produces a continuous force range of 90 to 160 N and a […]
Belt-driven electric actuators from IMI Norgren offer precise control
A new line of belt-driven electric actuators from IMI Norgren is designed to meet the force and extreme loading requirements for machine builders and plant engineers looking for an alternative to pneumatic actuators. NB27 single rail belt-driven linear actuator features a unique arc belt technology that improves traction for higher thrust. These single rail actuators […]
What are roller chain wear indicators?
Rollers chains, as a mechanical power transmission method, and like any mechanical system, are subject to wear over time and with continued use. Just how much it wears depends on a number of factors including whether or not the chain is properly lubricated and the amount of loading, among other things. So how does one […]
