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 rot… ...

Multiple quadrature encoder support: Mixed-signal FPGAs also offer another benefit for motor control – the capability of driving multiple motors (axles) simultaneously with single mixed-signal device.

How to Control a Stepper Motor Using a Computer. Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers.

Consider a side-by-side comparison of a traditional, open loop step motor system and a fully closed loop system with incremental encoder and servo control firmware that close the current loop of ...

There are a lot of fun projects you can do with stepper motors salvaged from old printers or disk drives. However, it isn’t always clear how to connect to some strange motor with no markings … ...

The indexer then provides step and direction data to the secondary motor-drive system based on the incoming encoder steps and the programmed move sequence.

The encoder has a high resolution of 4000 CPR, with quadrature, it can reach 16,000 pulses per revolution. A 5-V and 24-V encoder is available, each with a line driver.

Rotary encoders are commonly deployed in the closed-loop rotor systems used in a wide variety of applications from robotics and high end photographic lenses to opto-mechanical mice and trackballs to ...
