Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

For any designs that deal with large motors, isolation is a desired characteristic for both control and sense loops. Turn on, turn off, changes in load, changes in power, and unexpected events can ...

Why are there so many different angle encoders on the market? Why do they use different scanning and measuring methods? And which one should a designer choose? To answer those questions, engineers at ...

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rotate ...

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

If you have a motor and you’d like to know where the shaft position is, you are likely to turn to an optical encoder scheme. However, as [lingib] points out, you can also use a magnet and a ...

Featuring a postage-stamp-sized scanning unit along with high accuracy, Heidenhan’s incremental exposed linear encoders will likely fit the needs of stage manufacturers or anyone using linear motors ...

A quadrature encoder uses two output channels offset in phase to detect both direction and position with greater precision.

With the introduction of its EES37 single turn encoder and EEM37 multiturn encoders, SICK has completed its product portfolio for HIPERFACE DSL® standard servo motor feedback systems, while achieving ...
