11/04/2009 Maximize Motor Efficiency with Encoder Feedback
When comparing all the different types of electric motors currently available; the Permanent Magnet Brushless DC Servomotor (PMBDC) can provide the highest continuous torque density (i.e., torque output per unit volume) along...
11/04/2009 Resolvers vs Encoders for Motion Control
The phrase “more precise control” would generally drive the solution towards an encoder over a resolver. The application of dry food packaging however might tend to drive it back towards a resolver. Here are some characteristics...
11/04/2009 Encoders, Bearings and Reliability
Some rotary encoders are designed with bearings and some are not. Over the years, bearing manufacturing has improved, and consequently the reliability of bearings has generally improved. Still, there are applications where a...
11/04/2009 Encoders for Brushless Motor Commutation
The process of steering current through the appropriate motor windings in order to produce output torque is called commutation.In brush motors, commutation is accomplished electro-mechanically via brushes and the commutator.In...
