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 ...

As you may have noticed, I’ve been working with an STM32 ARM CPU using Mbed. There was a time when Mbed was pretty simple, but a lot has changed since it has morphed into Mbed OS. Unfortunately, that ...

This application note describes the Quadrature Encoder peripheral on the Z32F128 device and provides two examples of peripheral usage. The quadrature encoder decodes the signals received from an ...

Targeting brush motors running at less than 100W with quadrature encoders, the 3C20 digital-motion controller claims a 32-bit or greater precision in position, velocity and acceleration, and jerk ...

The sensing mechanism in an incremental optical rotary encoder consists primarily of a light source, code wheel, and optical detector. As the code wheel turns, a ring of alternating opaque and ...

The engineers at Moticont, Van Nuys, Calif., designed two new high-speed, direct-drive linear motors, part of the company’s SDLM series also known as Electric Cylinders. The compact motors measure an ...

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

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 ...

Rotary encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by the ...

If you are a novice to rotary encoders for human-machine interface, there is a potential pit-fall. Otherwise called quadrature encoders, they deliver two-bit gray-scale binary on rotation, with the ...
