PHD Inc. now sells a new Series ESU electric actuator — the ESU-RB. This linear actuator incorporates a ballscrew and features a robust enclosed design with a high capacity rail-bearing system. These features let the actuator deliver exceptional moment and load capability. The ESU-RB electric actuator is available in three sizes with travels lengths up […]
New DR Series compact electric cylinders from Oriental Motor
Oriental Motor now sells DR Series compact electric cylinders based on 28-mm AZ Series or PKP Series stepper motors. The DR Series is available with an AZ Series or 2-phase PKP Series base motor. The DR Series is a linear motion actuator that incorporates a precision ball screw into a stepper motor … saving space, […]
Linear shaft motors see increased force capabilities thanks to advances in magnets
By Paul Denman • Applications engineer and business development • Nippon Pulse America Today most linear-motion designs execute their strokes with actuators based on stepper motors or brushless dc (BLDC) servo motors. Such designs have an inherent complexity due to the fact that the motors and its gearing and encoder must essentially hang off the […]
Linear guides, power transmission, actuators see unexpected applications
Our 2020 survey of the industry indicates an unabated trend towards more automation of previously static or manually tended systems. Key to these new offerings is installation simplicity for OEMs and end users of linear components for linear axes … as well as positioning stages and Cartesian robots. In fact, Cartesian robots (also called linear […]
XY2Z-theta motion system improves wafer inspection for the semiconductor industry
For more than fifty years, the Dutch linear-motion company PM has developed and produced precision linear and rotating bearings and slides. It focuses on applications requiring smoothness and stiffness from their linear bearings … and continues to expand its standard range of linear components. But customization is becoming the norm — and now, catalog products […]
Electric actuators help reconfigure rooms in futuristic flexible residential construction
Traditional residential construction is fraught with inherent inefficiencies. Bedrooms are infrequently used during the day, while living rooms are unoccupied overnight. At a time when real-estate prices are climbing (especially in urban areas) the desire for single-purpose rooms inflates prices. Plus energy consumption is rising in many parts of the world … so the need […]
Zygo Names SCHNEEBERGER as a 2019 outstanding supplier in quality performance
Zygo Corp. has named SCHNEEBERGER Inc. as a 2019 Outstanding Supplier in Quality Performance. SCHNEEBERGER, a leading innovator in linear technology, was one of only a handful of companies able to qualify for the elite award. Zygo awarded SCHNEEBERGER its Preferred status after rating the company for excellence across a range of key metrics, including […]
Review of linear actuation complemented by guide wheels
Linear bearings based on steel guide wheels often complement motor-based linear actuation in two challenging application types: Long-stroke linear-motion axes as those driven by belts, linear motors, or rack-and-pinion sets Linear systems in harsh environments subject to hot and humid conditions, abrasive materials, extreme loading, and corrosive chemicals. Recall that wheel-based linear guides are systems […]
Boosting productivity with the right direct-drive motor and linear-motor feedback
Feedback options for linear motors and direct-drive torque motors abound. The most common employ optical, magnetic, capacitive, or inductive measurement. Here we explain how the key application parameters of precision, cost restrictions, and insensitivity to mechanical characteristics and environment dictate which technology is most suitable. By Steffen Preg | CEO • SIKO Products Inc. Machines […]
How to size a rack-and-pinion system for a precision motion axis
In a previous motion-sizing article, we reviewed how to properly specify a ballscrew-driven motion axis. Here we review how engineering teams can use a similar approach for sizing rack-and-pinion-based servomotor-driven axes on the same five-axis gantry. We’ll use manufacturer software to work through the application. By Sixto Moralez • Regional motion engineer | Yaskawa America […]
