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

maxon motorWed, 26 Nov 2014

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

Motion-centric machine design

White paper: tailored automation solutions for performance-driven machinery download

AerotechFri, 21 Nov 2014

Today’s machine builders confront a new era of risks, as globalisation increases competition and the internet rapidly disseminates information about products and markets. The highest priority for designers of performance-driven machinery is to reduce the various risks confronted across the machine design, development and maintenance lifecycle.

White paper: advanced landing gears for improved impact absorption download

Cedrat Technologies S.AThu, 20 Nov 2014

This paper from Cedrat Technologies is devoted to the presentation of adaptive impact absorbers applied as aircraft landing gears. The presented work discusses a possibility of utilisation of active dampers based on piezo-actuators and magnetorheological fluids (MRF) as the actuator for the proposed system. Control issues of an impact absorption system are widely presented. 

'Power factor calculation by the finite element method'

Technical article: power factor calculation by the finite element method download

CedratFri, 14 Nov 2014

Analytical methodology remains the most important daily work tool of motor designers. The use of analytical tools is important because it reduces calculation time — especially during optimisation. However, there are some important phenomena that are not always evaluated, particularly when ECM (equivalent circuit models) are involved. For these, numerical methods derive the best results. The use of finite element analysis is very important because it provides detailed simulation and ...
