Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

[Tobias Kuhn] had watched a YouTube video about a robot arm which used servo motors, and wanted to try making one himself. But he found it hard to get slow or smooth movements out of the servos. Even ...

The EEWeb Design Contest First Edition sponsored by Arduino and Altium is now open for submissions. This inaugural contest challenges hardware design enthusiasts from all over the world to develop an ...

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 ...
