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 ...

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 ...

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.

(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 ...

A standard reflective encoder module contains two digital output channels for direction sensing, but needs another module for indexing. Similarly, motion A standard reflective encoder module contains ...

Alignment of optical encoder commutation signals to a Brushless DC (BLDC) motor could be thought of as being comparable to timing the distributor on a car engine. The distributor tells the spark plugs ...

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 ...
