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 ...

Sometimes you can search the internet to locate a suitable stepper control library, but you can’t find what you want, which leaves you with no other choice but to write your own custom code. Sometimes ...

The new motor driver supports both sensor-based and sensorless control while aiding configuration with programmable flash.

Microcontrollers may dominate today’s stepper motor projects, but there’s a charm in driving them with pure CMOS logic. Try ...

[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 ...

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 ...

Melexis has introduced a 40W driver with four half bridges and field-oriented control to operate three-phase brushless motors and four-wire stepper motors. A CPU is included and both sensor-less and ...

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 ...

To achieve CNC functionality, machine shops can convert hand-wheel controls to automated controls with stepper motors. The process depends on the machine type and layout … CNC machine centers offer ...

“One of the most highly developed skills in contemporary Western civilization is dissection: the split-up of problems into their smallest possible components. We are good at it. So good, we often ...
