Stepper motors are brushless synchronous electric motors powered by direct current that rotate in steps, keeping the rotor stationary under a specific power supply. A well-defined sequence of PWM ...

For those looking to build their own clocks, one of the easiest ways to get started is with a pre-built module that uses a simple quartz oscillator and drives a set of hands. This generally doesn’t ...

Simple hardware and software techniques are illustrated in this project wherein 3 common 4-coil stepper motors are driven and controlled using a single Stamp II board. The device is a modified version ...

Proper evaluation of torque margins across the full motion profile prevents stalling and ensures consistent performance under varying load and speed conditions. Mechanical resonance can cause ...

A new open source servo stepper designed for makers and developers has been launched via Kickstarter this week offering industrial reliability in an affordable open source design. The AnanasStepper ...

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...

Building an electric motor isn’t hard or technically challenging, but these motors have very little in the way of control. A stepper motor is usually employed in applications that need precision, but ...

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 ...

The USB's many advantages have led designers to come up with a wide range of applications for the bus. For example, the figure shows a USB-based controller for four stepper motors built using ...
