When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

The world is digital today, and most information is represented in numbers. However, human nature is more “analog” and information is better represented in the old-fashioned way, using pointer gauges ...

Based on the Motorola (now Freescale) heavily used but obsolete SAA1042 stepper-motor-driver IC, this Design Idea describes a CPLD (complex-programmable-logic-device)-based implementation of a stepper ...

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 ...

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 ...

Developers, makers and hobbyists that are looking for a way to control up to four motors using their Raspberry Pi mini PC. May be interested in a new control board that has been created by Justin ...

Toshiba Electronics Europe has introduced a new stepper motor driver integrated circuit, the TB67S579FTG, featuring its ...

Kevin Teresa based in Switzerland has created a new open source stepper motor driver board with 6A / phase and 48V capabilities enabling it to drive a wide variety of stepper motors from NEMA 17 to ...

New motor technology reduces heating effects in the motor, allowing it to run up to 104 °F (40 °C) cooler than the conventional stepper motors. This offers benefits including 100% torque utilization ...

[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.
