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 ...

It’s increasingly common for designers to pair stepper motors with motion-control SoCs. In fact, more design engineers than ever are setting up SoCs themselves for motion applications. These chips ...

Stepper motors are impressive little engines that may not be getting the credit they deserve, as they are a relatively important part of our electronic lives. Printers and CNC machines are ...

[Arshad Pathan] let us know about his latest project, a modular code lock that can be adapted to many different situations. The user interface is made up of a character LCD screen and a 3×4 keypad.

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...

Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...
