The Stepstick and Pololu motor drivers are the heart of just about every Reprap electronics board, but they can go bad. The usual way of testing these things is to rig up a microcontroller on a ...

This Design Idea further develops a previous one integrating a stepper-motor driver in a CPLD (Reference 1). However, this idea integrates not only the driver, but also a simple one-axis stepper-motor ...

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 ...

Electronic enthusiasts may be interested to know that a four axis stepper motor driver designed specifically for “creative coders” is now available from the Crowd Supply website. The STEP400 is ...

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 ...

The A4979 flexible microstepping motor driver with built-in translator is designed to operate bipolar stepper motors in full, half, quarter, and sixteenth-step modes, at up to 50 V and 1.5 A. The ...

Haydon Kerk Motion Solutions, Inc., a premier manufacturer of engineered linear motion products, announces the addition of stepper motor drivers available for 24 hour shipment. A variety of stepper ...

Demand Peripherals, Inc., makes an FPGA-based robot controller that gives a robot or other industrial control systems the high I/O pin count and precise timing that a Linux laptop or single-board ...

ST Micro's Markus Ekler explains the technology and derives thermal loss equations that can be used to support design decisions for stepper motor driver circuits. One constant trend in the automotive ...

[Mark Rehorst] tells us about a tragic incident involving an untimely demise of $200 worth of motor driving hardware, and shares a simple circuit so that we can prevent such tragedies in the future.
