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… ...

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.

Commercial shaft encoders use magnets and Hall-effect sensors, or optical sensors and encoder discs. But these can be quite expensive, so [Hello1024] hacked together an alternative in an afternoon.

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 ...

Gearing up: on the left is an illustration of a 4×4 array of meta-atoms that are rotated using gears and a stepping motor. On the right is a single meta-atom at the centre of rings that illustrate its ...

Choosing a stepper drive over a servo has certain advantages, namely price. Where a stepper will do the job, consider using one — but not until you've read these expert tips and ...

This reflective encoder from Avago Technologies, San Jose, Calif., is called the AEDR-850x and features built-in interpolation for high-resolution measurement on closed-loop stepper motors ...

Toshiba has introduced a constant-current 2-phase bipolar stepping motor driver, which is designed for automotive use, and is claimed to streamline motor system implementations.

Toshiba launches a constant-current 2-phase stepping motor driver IC for automotive applications including heads-up displays.
