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 […]
What is a direct drive motor?
A direct drive motor is any motor — rotary or linear — in which the load is connected directly to the motor, without mechanical transmission elements such as gearboxes or belt and pulley systems. In other words, the motor directly drives the load. Direct drive rotary motors Rotary direct drive motors are often referred to […]
Low-profile linear stepper motor stage from H2W Technologies
The LSS-016-04-006-01A-ME is one of a revolutionary new series of low-profile linear stepper motor positioning stages that integrates an absolute linear encoder and a single-axis linear stepper motor stage. This enables the linear stepper motor stage to operate as a 2-phase brushless linear motor when coupled with motion control electronics provided by H2W Technologies (H2W). […]
SUPERWURM worm farm uses motion components from igus
One automated worm farm in Germany to breed and grow worms includes machines to continuously lift, transport, release, stack, drill, and spray giant red worms called dendrobena. Duren-based SUPERWURM uses robots and automated guided vehicles (AGVs) until the worms are ready for sale to fishermen, as food for animals, and as natural fertilizer for gardens […]
160-page catalog on piezo motor solutions from PI
PI’s new comprehensive piezo motor solutions catalog covers a large number of linear, rotary, and multi-axis motion systems based on a variety of piezo motor types along with their appropriate controllers and drivers. Piezo motors have excellent dynamic properties, such as high acceleration and fast start/stop behavior, along with nanometer precision and stability. In contrast […]

THK to show low-inertia ballscrew-spline BNS-V during IMTS
In two weeks, IMTS visitors will be able to see THK’s ballscrew-spline BNS-V at booth #134514. Featuring an exceptionally compact and lightweight structure, the low-inertia BNS-V enables quick starts and stops during high-speed operation. The BNS-V is a stroke-rotary unit with ball screw grooves and a ball spline groove that cross one another on a […]
Beam deflection equations for linear systems
When a linear guide, such as a round shaft or profiled rail, deflects or sags, the bearings that travel along the guide experience edge loading (a higher load concentrated at the ends of the bearing), which can cause rough, irregular movement, increased wear, and reduced bearing life. And when a linear guide is incorporated into […]
