When you turn the volume knob on a car audio system, you feel a clicking sensation, and the numbers on the screen go up one ...

Position measuring devices that rely on the principle of mutual induction include resolvers, linear variable differential transformers (LVDTs), and inductive encoders. Two of these technologies — ...

Selecting the wrong encoder can lead to downtime, costly redesigns, and unreliable feedback. This guide breaks down the fundamentals of rotary and linear position sensing — and explains when ...

A new series of commutating motor feedback encoders is said to make it easier and cheaper for designers to improve machine performance and productivity in stepper and servo motor applications.

This column wraps up our discussion of encoders with information about resolvers, which provide angular data over 360 degrees. A resolver looks like an electric motor, with a rotor and a stator, but ...

A rugged, self-contained, resolver-based encoder, the Shaft-Tracker from Computer Conversions Corp. can replace less reliable optical shaft encoders. The device provides both incremental and true ...
