Positioning Stage

LinTech (Monrovia, CA) offers the 610 series totally enclosed positioning stage in stroke lengths from 6 to 60 inches (150 to 1520 mm). The screwdriven linear positioning systems use a low-friction, preloaded, recirculating linear ball bearing system that rides on precision ground linear rail guides. The linear rails are mounted to an extruded aluminum base, which provides support over the entire travel of the table’s carriage. The load is mounted to a machined aluminum carriage, which has threaded stainless steel inserts. There are 38 different acme and ball screw options.

DryLin® E7 plastic linear plain bearings versus PTFE-lined plain bearings

Linear plain bearings are becoming commonplace in today’s manufacturing industry. As technologies and material sciences have advanced, so have the capabilities of linear plain bearings, particularly those made of plastic, such as the DryLin® series of self-lubricating linear bearings from igus®. This whitepaper will compare how they outperform a competitive linear plain bearing technology, which uses a PTFE-based, bonded liner, in both wear and friction testing.

Choosing the Right Potentiometer for Reliable Sensing

In today’s market, there are a variety of available types of position sensing systems. It is important to compare unique features to application needs in order to find the best fit.A potentiometer sensor is an electromechanical component that consists of a resistor where the voltage divider value can be measured at any position by means of sliding contacts between the applied voltage values. Physically, a potentiometer consists, at a minimum, of a resistance track, a collector track, and a sliding contact that can be moved along the resistance track by means of mechanics (Figure 1). The movement of the sliding contact can be rotatory (angle) or translational (path).

Embedded Virtualization Enables Highly Integrated “Soft Motion” Platforms on the PC

With the increased processing power that PCs have attained, a complex machine that used to require an expensive and dedicated hardware-based motion control solution can now be accomplished on a multicore PC running on a real-time operating system (RTOS).

Imitative Robotic Control: The Puppet Master

Automated systems can have a hard time completing complex tasks in a timely manner. When controlling a robot outside autonomous mode, a good control device needs to give the user full control of the system while enabling the mission to be completed in a quick, accurate, and efficient manner.

Service Robots Use Flat Motors to Provide Reliable, Safe Motion

Unlike industrial robots for manufacturing, service robots come with their own specification requirements aimed specifically at the end user, and the most discriminating user at that — a human being. That’s why designing and manufacturing service robots takes a particular set of skills and engineering expertise.

Encoders Ensure Position Accuracy of Linear-Torsion Tester

Instron (Norwood, MA) manufactures materials testing equipment and accessories that are used to test samples ranging from components for jet engines to medical syringes. The company’s ElectroPuls systems are used for fatigue testing, which examines the behavior of materials under fluctuating or cyclic loads in the elastic regime. The E1000, E3000, and E10000 fatigue test systems are suited for biomedical/biomechanical research applications, and feature a wide dynamic performance range and low force characteristics. The all-electric systems use linear motor technology to eliminate the need for ball/lead-screws, and enable slow-speed static tests through to high-frequency dynamic tests at over 100 Hz.
