Cross section of the linear actuator

Technical article: a comparison of different simulation models downloadweblink

CedratWed, 28 Jan 2015

  In this paper the question will be discussed where and when the expense of a CoSimulation with two established simulation tools such as 1) Matlab/Simulink and 2) FLUX is worthwhile. A linear actuator is used as an example, which is simplified and abstracted from a real part due to confidentiality reasons.

Technical article: correct handling of bearings maximises operating life download

BardenWed, 28 Jan 2015

Experience shows that up to one third of bearing failures can be attributed to improper handling and faulty mounting. Moreover, these problems get worse as bearing tolerances become more exacting, says Gary Hughes, product engineering manager at The Barden Corporation.

maxon motorTue, 20 Jan 2015

When we think of a gearhead, we tend to assume that it is incompressible and rigid. The truth is it still bends, compresses and has elastic properties. This has an effect on the difference between the perceived motion (encoder counts) and the actual motion of a drive system — we are not where we are supposed to be. According to Mark Gibbons of maxon motor, when measuring anything we need to keep in mind how the instrumentation works and what are its limitations.

White paper: bistable piezoelectric harvester for wideband mechanical frequency excitation downloadweblink

Cedrat Technologies S.AFri, 9 Jan 2015

This white paper focuses on a bistable harvester designed and invented by the SYMME laboratory using amplified piezoelectric actuator (APA) technology and the industrial know-how of Cedrat Technologies.

White paper: active cardiac stabiliser — first in-vivo experiments using a robotised device downloadweblink

Cedrat Technologies S.AMon, 5 Jan 2015

Off-pump coronary artery bypass grafting (CABG) is still today a technically difficult procedure. In fact, the mechanical stabilisers used to locally suppress the heart excursion have been demonstrated to exhibit significant residual motion. Cedrat Technologies proposes a novel active stabiliser that is able to compensate for this residual motion.

Technical article: selecting a brushed or brushless DC motor — decisions, decisions downloadweblink

maxon motorMon, 22 Dec 2014

Are brushless motors just a technology fad or can they be of real benefit to design engineers? As maxon motor explains in this article, brushless DC motors are more popular than brushed motors at the moment, but the fundamental question when choosing a motor is ‘what does it need to do?’

White paper: vibration energy harvesting in aircraft using piezoelectric actuators download

Cedrat Technologies S.AWed, 17 Dec 2014

The amplified piezoelectric actuator (APA) integrating a mechanical amplifier can be interesting where the efficiency of the standard actuators is poor. In this paper from Cedrat Technologies, the electrical harvesting characteristics of the APA in a proof mass configuration is studied.
