Thomson Industries, Inc. has unveiled their new Electrak MD, a more compact electromechanical actuator that retains all of the intelligence built into its larger counterparts. Mobile off-highway, material handling and factory automation applications can benefit from the compact actuator with up to two kilonewtons (kN) of force, advanced onboard electronics and J1939 CAN Bus support. […]
Linear servo brush-type amplifiers for voice-coil actuators
H2W’s new dc linear brush-type servo amplifier, the LCAM 5/15, is suited to drive the company’s line of voice coil linear actuators. Linear amplifiers provide continuous current flow to the motor which prevents any dead-band issues that occur in many PWM type amplifiers. Additionally, linear amplifiers have low EMI, and no audible noise that also […]
Magnetically preloaded single-axis linear stepper motors from H2W
H2W Technologies’ single axis linear stepper motors are suitable for high-speed open-loop positioning applications. They can perform at speeds of up to 80 in./sec [2 m/sec] and strokes of up to 68 in. [1.7 m]. Linear stepper motors are capable of precise position, velocity, and acceleration control when coupled with a micro-stepping drive and indexer. […]
igus develops new online shop for energy chains
igus has developed a new online shop for energy chains where designers can filter products by category, application, and specifications. The new shop also includes pricing, and allows designers, engineers, and materials specialists to have all of the parts listed in one user-friendly website. The shop can be accessed here: https://www.igus.com/e-chains/cable-carriers The new shop allows […]
New simulation software from PI aids hexapod selection
Powerful new simulation software from PI (Physik Instrumente) determines if a hexapod is suitable for a specific positioning task, in terms of workspace, load, center of mass, and operating orientation. The tool helps in making the correct choice for the application at hand. A hexapod, also known as a Stewart Platform, offers motion in 6 […]
New 20-mm linear stepper motors from Nippon Pulse
Nippon Pulse has introduced its smallest linear stepper motor yet, the PFL20 Linearstep. The PFL20 is a highly efficient, high thrust tin-can linear actuator with a 20-mm diameter and a bipolar winding. The PFL20 is RoHS-compliant, has a 30/60 mm effective stroke, and can reach 6 N of force at 200 pps. With 24 steps […]
Linear guides with more rollers feature high load capacities
NB Corporation’s EXRAIL linear guide has more rollers in less space than other linear bearings, which increases load capacity and disperses the load more evenly. It has longer rollers for greater contact surface and less contact pressure. In comparison to presently available linear guides, the EXRAIL slide guide provides smoother movement. It uses multiple small […]
Tolomatic expands hydraulic-class electric actuator force range to 50,000 lbf
Tolomatic’s expanded extreme-force electric actuator family now includes the RSX128 actuator, rated up to 50,000 pounds of force (222.4 kN). Ideal for replacing hydraulic cylinders and designed for 100 percent duty cycle, the RSX actuator features Tolomatic’s precision-ground planetary roller screws for long, consistent operating life in challenging environments. Applications include assembly, metal fabrication (pressing, […]
Slide ways for precise motion control
NB Slide Ways are non-recirculating linear motion bearings used primarily in optical and measurement equipment where high precision movement is required. The SV style consists of two roller cages with precision rollers in a cross arrangement and four rails with V-shaped raceways. The SVW has one rail with V-shaped grooves on both sides and two […]
Tolomatic develops open-source, low-cost ventilator actuation prototypes for COVID-19 patients
In an effort to support the global need for medical ventilators, Tolomatic has dedicated a team of engineers to the development of highly efficient emergency ventilator concept systems using electric linear actuators. Tolomatic’s solution is a new type of ventilator that operates using an electric linear actuator. These prototypes automate a non-invasive, positive-pressure resuscitator (also self-inflating […]
