The electric motor is the fundamental building block of almost all robotic projects but, without some form of feedback, it lacks the precise positional control required for the task. Small servos from ...

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 ...

Position encoders are sensors that, when used in industrial settings, produce critical motor information such as speed and position. The encoder delivers data for display or data that may serve as ...

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 ...

Melexis is aiming at electric motors with family of angle-sensing absolute magnetic encoder ICs that can work at high speed and typically deliver 1° accuracy or better. “By detecting the three ...

A new magnetic digital encoder featuring 14-bit resolution, differential outputs, and a speed range of up to 200-k e-RPM offers accurate and cost-effective position sensing for various robotic and ...

(Nanowerk News) Global precision motion control and nanopositioning industry leader PI introduces a new high dynamics linear motor stage family, the V-574 - a new series of linear positioning stages ...

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.

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 ...
