Giving soldiers a high-tech leg up
7

Those whiz kids at Darpa are at it again. This time they want to use technology to let soldiers carry up to 220 lb in backpacks over all types of terrain,terrain vehicles can't get through, and for extended lengths of time.

Torque motors do the trick
4

Direct-drive technology seems to be an ideal way to increase productivity, accuracy, and dynamic performance. It can also lower costs, simplify designs, and reduce wear.

Basics of Configuring Drives

The key to many motion applications is in sizing the drive components lying between the motor and load

Linear actuators get a servo look
1

New actuators borrow ideas from linear motors to provide controlled displacement on a budget.

3D & 2D CAD Files

Our on-line CAD library contains 2D files in .dwg for AutoCAD and .dxf for other systems; and 3D files for Pro/Engineer and STEP. Access to our other on-line CAD drawings is now integrated into our on-line catalog.

Stepmotor
Selecting the Best Stepmotors

Interestingly enough, many stepmotor failures can be traced back to the selection process.

Servomotors Stabilize and Position Sensor Turrets on UAVs
1

Lightweight, high-efficiency servomotors stabilize and position sensor turrets on ultralight unmanned aerial vehicles.

Torque, Speed, and Yogurt Cups
1

Two servomotors will drive a single shaft in what’s billed as the world’s largest trim-in-place thermoforming machine

Coupling Motion Systems for Zero Backlash

Selecting mechanical couplings for machinevision and optical-inspection systems requires a trade-off between damping and rigidity

Misumi Actuators
Linear actuator basics

Basic components and tradeoffs that surround the use of linear actuator modules

Servomotor Measures Its Own Inertia Load
2

Advanced servomotor systems need an inertia load parameter for proper tuning. This process uses the servomotor in the machine to plot the true inertia of the load.

Linear motor actuator
Linear motor vs. belt-drive actuators

Woody Yen from THK America Inc. talks about the advantages of linear-motor-driven actuators and belt-drive actuators with Lee Teschler of MACHINE DESIGN. 4:08

Speeding mechanical design with Engineering Fluid Dynamics

A recent independent study reports best-in-class companies are twice as likely to use fluid-flow simulation as their counterparts.

Damping Grease for Design

See how damping greases can cost-effectively control motion, noise and vibration in mechanical and electro-mechanical devices.

New Track-Wheels for Robots
