Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...

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 ...

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.

Engineers use rotary encoders to measure the angular position of an attached device, such as a motor shaft, or to measure distance indirectly when used with a linear belt drive, for example. Rotary ...

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 ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

Same Sky has created an absolute encoder family for motor shafts from 9 to 15.875mm (5/8inch). Called AMT25 and said to be accurate to ±0.2°, the family relies on the same in-house capacitive ASIC for ...

In robotics, movements must be precise and well-controlled. As robots are asked to do more as industry becomes more familiar with the technology, there will be an increasing need for high accuracy ...
