The project utilizes scavenged stepper motors from disk drives or printers with some probing of an ohmmeter followed by some simple driver code on the microprocessor. The project utilizes scavenged ...

Driving a stepper motor can be a daunting task. Whereas, providing a voltage at the terminals of a DC motor causes immediate rotation, on a stepper motor, careful magnetic field commutation must be ...

It’s fair to say that building electronic gadgets is easier now than it ever has been in the past. With low-cost modular components, there’s often just a couple dozen lines of code and a few jumper ...

Stepper motors are now being used more frequently in industrial environments. Increased performance and reduced size make them increasingly attractive, and their application is no longer limited to ...

Find a downloadable version of this story in pdf format at the end of the story. A new controller IC, the L6470 for stepper motors, integrates the power stage along with a digital control core on a ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

The growing availability of customizable options for motors allows engineers to tailor motors to specific application needs, while modular designs simplify integration and reduce development time.

Makers, developers and Arduino enthusiasts searching for silent stepper drivers with high resolution encoders which are also Arduino compatible. May be interested in the new range of uStepper S line ...

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 ...

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 ...

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 ...
