Simple, non-contacting motor speed measurement

25/06/2013

Motor speed is usually measured by means of an internal sensor bearing or an optical encoder with fixed pulse counts, whereby a separate sensor or code disc is required for each pulse count. These are complex and rather inflexible techniques, a fact that prompted Contelec to take a fresh look at motor speed measurement.

How Ford Europe keeps an eye on wheel dynamics

25/06/2013

Ford Europe commits many man hours to acquiring data from prototype test vehicles at its test track at Lommel in Belgium and, during the past 13 years, much of its Road Load Data (RLD) has been derived using Kistler RoaDyn wheel force sensors over a wide variety of road surfaces.
